Why use VektorFlo® 7 MPa Workholding?
Most expensive CNC metalworking
machines are purchased without fixtures to hold
the work piece(s). With today’s sophisticated
machines making tool changes in fractions of
a second with accuracies we once thought nearly
impossible, the quality of part clamping is the
next most important opportunity for time savings
and productivity improvement. VektorFlo® power
clamps provide the “helping hands” to present
more parts to the machine spindle with less
effort, more consistency, and greater productivity
at a cost only modestly more than manual
fixtures. Use VektorFlo® because it can increase
your productivity.
Many of your machines are purchased without
integrated hydraulic power supplies. You have
a choice of pressure less than 7 MPa or more
than 7 MPa, a choice generally made based on
clamping device size. Machines may be
purchased with a power supply to deliver either
up to 7 MPa or above 7 MPa. This option, if
purchased with the machine influences the
pressure range of your choice in hydraulic
clamping devices. Other influencing factors are
the need for “live”, always connected,
“disconnected” hydraulics or “palletized” fixtures.
Vektek’s 7 MPa products are tested to over
1,000,000 cycles at full operational pressure
before they are included in our product line
assuring you the long product life you need to
keep your production lines operating.
The selection of any single brand of hydraulic
clamp, as any other important decision, must be
made from an informed, intelligent point of view.
Your choice should be based on many factors
influenced by your specific application. Other
factors can be used for general comparison and
are strong indicators of the overall quality of the
brand selected. Before making any decision, we
ask that you take time to accurately compare
product quality, product and information
availability, technical support and service both
before and after the sale. When you do, you’ll
find VektorFlo® 7 MPa above the rest! This is
why Vektek is the worlds leading manufacturer
of power workholding products.
Quality Product
At Vektek, we know that professional users
expect top quality products backed by
knowledgeable technical support. They also
expect ready availability of parts when needed.
Armed with this knowledge our team of engineers
began an extensive product development process.
Exhaustive research, design, development and
testing yielded a unified product line all of which
incorporate the following appropriate features:
 BHC™, a special black hard coating, makes
VektorFlo® bodies extra durable. This high
tech surface hardening process virtually
eliminates the bore scoring and scratching
that is the most common reason for seal
failures and leakage in some brands.
 Hardened and Chromed bearing surfaces are
incorporated to provide improved load
bearing areas where it is critical to device life.
 Every device is ported using standard G 1/4
or G 1/8 L-Series porting. Face seal porting
normally installs without leaking the first
and every time.
 Special seals and wipers help keep leaks from
starting by sealing fluid in and contaminants
out. Loaded lip and crown seals virtually
eliminate external (visible) and internal
(invisible) leaks. Most devices incorporate a
wiper to keep chips from entering the cylinder
and damaging the seal. VektorFlo® seals
have been tested in most common coolants
and found to be stable in all those tested.
 Warranty is an indication of a manufacturer’s
confidence in the ability of the product to run
"trouble free" for a specified time. Our
hydraulic products are warranted for one
year from date of shipment. For details see
our printed warranty statement.
Compare the durability and long life of
our devices with that of competitors. Prove it
to yourself. We welcome any head-to-head
challenge between our product and others in
the marketplace.

A typical customer finds that it goes like this:
 After several conversations with a Vektek
sales representative, you may uncover an
application where hydraulic clamping will
pay for itself in a very short time.
 Call us at your convenience and
discuss the application with one of our
Application Engineers. They may ask you to
send information about your current fixture,
part, machine and/or processes for them to
study and propose a clamping concept.
 To aid in your fixture design, CAD files for
each product are available to you online at
www.vektek.com or by requesting a CD from
your sales representative.
 One more thing to keep in mind . . . You can
have all this service at no charge! Call us

Planning
Introduction
Planning Your Power Workholding System...
Successful powered workholding does not
just happen. Like any other manufacturing
process, it must be carefully planned. But that
does not mean that you need to be a hydraulics
engineer to implement a powered workholding
system. Designing a system involves nothing
more than the common-sense application of
a few basic workholding concepts.
Applications for power workholding fall
into two categories: retrofits to replace and
upgrade clamping on existing fixtures; and new
fixtures designed from the outset with power
workholding. In both cases it is imperative
that you keep in mind the forces that can be
generated by power workholding devices. A
single device, small enough to hold in your hand,
can generate 26 kN of clamping force. If you are
replacing existing manual bolt and nut clamping
or toggle clamps, make sure that the fixture or
machine tool base will withstand the forces.
www.vektek.com
Using power workholding does not in any
way invalidate the principles of sound fixture
design. The 3-2-1 concept as it relates to the
location of the work piece in three planes is just
as applicable when using power workholding
devices as when using manual methods.
Workholding devices should be positioned in
such a way as to ensure firm contact between
the work piece and locating buttons, pins,
or surfaces.
Begin the planning process by asking
yourself the following:
 What do you want your system
to accomplish?
 What sort of operation is going to use
this system?
 What clamping "speed" is appropriate
for the speed at which your production
line runs?
1-800-992-0236
You should select "realistic" cycle times . . .
the shorter the cycle time, the larger the power
source required. For example, a pump with a
1/3-hp electric motor may be satisfactory to
reach clamping pressure on a given system in
three seconds. However, to accomplish the same
task in one second may require a pump with
a 1-hp electric motor — at a considerable
increase in both initial expense and operating
costs. So before you specify "instantaneous"
cycling, be sure the increased clamping speed is
really worth the higher costs for your particular
installation. Ask yourself if you can productively
utilize the seconds saved.
With this in mind, let’s proceed step by
step through a plan of attack for designing
your system.
A-1
Planning
Steps 1-11
A-2
Step 1:
Step 5: (Optional)
First, determine the nature of the operation
to be performed, the number of parts to be
processed per cycle, and whether operations will
be performed on more than one surface of each
part. Also determine the time that should be
allowed for part loading, unloading, and
clamping the part.
Consult your machine tool file to determine
the available work space on the machine table,
bed, or other surface, as applicable. Be sure that
the space available will accommodate the part or
quantity of parts to be processed according to
your manufacturing work-flow. If not, revise
your plan.
In the initial phases of system planning,
include adequate measures and devices to ensure
the safety of workers and equipment.
Normally you need to calculate the forces
required to overcome work piece weight and
friction and to move the part into position against
fixture stops if you are using positioning cylinders
as your first hydraulic operation
of your fixture.
Step 2:
Step 7:
Prepare an outline of the sequence of events
that will take place during the manufacturing
cycle. This will assist you in determining the
types of special sequencing valves that you
might need, as well as any external control
(such as a tie-in with machine controls) that
your application may require.
Step 3:
Calculate the cutting forces generated in the
machining process and note the direction that
these forces tend to act on the work piece. If you
are planning a retrofit of a manual clamping
system, you may use the torques presently being
used. However, it is recommended that cutter
forces be calculated as a precaution in such a
case to ensure that workholding devices are sized
to provide an adequate margin of safety. The
operation manuals of many machine tools
contain tables that list machining forces or simple
formulas for calculating these forces.
Step 4:
Plan your fixture(s) with positive fixed stops
to resist the majority of cutting forces and to
ensure correct location of the work piece using
the primary part locating features.
Step 6:
After you have determined the machine
cutting forces, it is easy to calculate the clamping
force required to hold the work piece on the
fixture or machine table. Again, a simple formula
is all you need to arrive at an answer for the
materials you’ll be working. Give us a call if
you need help.
Determine where clamps should contact the
part to hold or support it securely and to avoid
interference with machine operations. If clamps
cannot be located so as to avoid interference with
manufacturing operations, it will be necessary
to use an external control device to move the
clamps out of the way as the need arises during
the manufacturing sequence. This will require
that electrically actuated valves be used to control
the offending devices separately.
Step 8:
Determine the type and number of
workholding devices you need based on the total
clamping force required and clamping positions
you’ve selected; on the size, strength and shape
of the part; and on the machine operation.
Step 9:
To help determine the capacity of the power
source you’ll need, add the total oil displacement
requirements for the devices you have selected.
Then choose a power source with equal or greater
capacity and determine if it will operate the
system within your clamping time constraints
by working out the following formulas:
(Device Cap.) ÷ (L. P. Flow) = Position Time
cubic centimeters (cm3). Position time is time to
position expressed in decimal parts of a minute.
Where . . .
If total estimated clamping time is not
within the cycle time requirements you’ve
targeted but is within device limitations, a larger
power source is required — one with greater
capacity. Select such a source and repeat the
above calculations to ensure that it will provide
the clamping cycle times required.
If the total estimated clamping time in the
initial calculation is significantly less than the
time allowed, your initial power source selection
may have been too large. In such a case, select
a smaller power source and repeat the above
calculations to ensure that it still provides the
clamping cycle times desired. If a smaller power
supply is not possible, a flow control may be
used to limit the speed of device positioning.
This will help devices perform correctly and not
“bounce” or become damaged by excessive flow.
Additional factors you should consider
when selecting a power source include shop
floor plan and/or machine layout and your
own preference for the type of power source
(shop air vs. electric).
If desired, large electrical power sources
may be used to supply several workholding
systems, each operating independently at several
machines. In this case, the timing and sequence
of operations for each individual system must be
calculated as shown above in order to arrive at
a size for the power source.
Step 10:
Select valves and other control components
to accomplish the sequence of operations you
outlined in Step 2. See the valve section of this
catalog for guidance.
Step 11:
Select appropriate safety control
mechanisms. All VektorFlo® electrical power
modules have a hydraulic pressure switch as
standard equipment to ensure that consistent
forces are maintained at all times. However,
when a power source is used to power several
separate individual systems, each system should
also have its own pressure monitor.
Where . . .
“L.P.” flow is low pressure pump oil volume
expressed in cubic centimeters/minute. “Device
Cap.” is total device oil capacity expressed in

Frequently Asked Questions
A-4
This list of questions was developed by
listening to customers just like you when they
asked, “Why didn’t I know that?” Before you
order devices, build your fixture or even consider
your design complete, we suggest that you run
through this checklist to identify some common
problems you might encounter.
What is the advantage of double
acting cylinders?
Double acting cylinders will assure full
cylinder retraction on a timely basis even in
systems where restrictions such as small orifices
or long tubing runs have been introduced. The
use of double acting cylinders is especially
important when “return” time is critical (as in
some CNC systems).
What should I watch for when selecting
fittings, tubing and hoses ?
Some fittings and hoses which are locally
available (not from Vektek) have extremely
small orifices which restrict flow. The use of
G 1/8 or similar size fittings can have this effect
on a system. This restriction is even more
pronounced when introduced at a main feed
line. This can happen with some fittings and
many hoses.
Excessive tubing length can create a
column of oil which is very long. Friction created
by moving oil through tubing and hose will slow
response times because of the inertia of the
column of oil and increased back pressure of
returning oil.
Proper sizing of fittings for main feed
lines and device supply lines will normally be
accomplished by using an appropriate fluid
distribution manifold. Device fittings are G 1/4
or G 1/8. Main feed lines should be at least
8 mm to avoid restrictions.
Is my plumbing free of obstructions
and contaminants?
Tubing must always be flushed after
cutting. Even if not cut in your shop, it was cut
before it came to you. Chips, burrs, dirt and other
contaminants have collected inside your tubing
and drilled passages. These contaminants can cut
device seals, damage valve sealing surfaces,
cause erratic operation and reduce service life if
not cleaned prior to fixture start up.
The use of improper fittings can also cause
obstructions and restrictions. Be sure you haven’t
created obstructions by using non-standard parts.
Is my pump of appropriate size? It is
rated for____l/min, or _____cm3 per
minute? My devices require a total of
_____cc. of oil to actuate.
For most normal size fixtures, a pump
rated over 8 l/min. (Liters per minute) is not
recommended. If your pump is rated much more
than 4 l/min, call us, we’d rather give you sound
advice now than have you damage clamps and
have to sell you replacements. Be sure that you
do not exceed the recommended flow rates for
your system. If you aren’t sure, ask us.
My pump runs continuously. Is it the
right type of pump?
Call us. It can often be made to work.
Some modifications will probably be necessary.
I’ve been using a dump pump (builds to
pressure, shuts off and releases pressure
automatically). Is this pump suitable
for workholding?
It can be. It will work if the circuitry is
properly designed. It may require special circuit
modifications to work properly.
I want several sequenced operations to
happen on my fixture. Can I put three
or four sequence valves in series?
We do not recommend it. Our sequence
valves operate better if run directly from the
main hydraulic supply line and set at different
pressures. We recommend at least
1 MPa differential.
1-800-992-0236
When I use a dial indicator on my part,
it bends when it is clamped. Why?
Clamps should be positioned directly
opposite a fixed locator, hydraulic support or
other supporting element. This element may be
a part of the fixture, a solid portion of a rigid
part or a properly sized floating locator such as
a hydraulic work support. If your clamp is putting
force into your part which is not transmitted
directly into a solid stop, it may distort the part.
Clamping on draft angles or “mushrooming”
the part with excessive force can also cause
part distortion.
I hold all four corners of my part on
solid locators. When unclamped, it
seems to “spring” back into a different
shape. Why?
First, holding all four locating points in
exactly the same plane on your fixture is virtually
impossible. (See your favorite text on fixture
design for an explanation of 3-2-1 fixture
building principles.) Second, because your part
can’t have all four of these points in the same
plane, your part is distorting when clamped.
Other factors such as stress relief may cause the
part to change its “free” shape after machining.
I want to limit the pressure into a
sequenced hydraulic circuit. Which valve
would I install first?
We recommend that you avoid putting one
special function valve behind another if possible.
If you must, put the pressure limiting valve after
the sequence valve. This avoids the limiting
valve being shut off before the sequenced circuit
is fully actuated.
I want to make a cut directly against
(into) a clamp. Is this possible?
Yes, it is but it will require special design
considerations. We encourage that cutter forces
always be directed toward a fixed stop. A fixed
stop is designed to prevent part movement. A
clamp is designed to position and force a part
against a fixed stop. In order to machine “into”
a clamp, the clamp must be sufficiently sized to
resist all cutter and machine forces or the part
will tend to shift.
www.vektek.com
Planning
My company uses a lot of brass on our
product. Can I use these to connect my
7MPa hydraulic clamps?
Yes, brass fittings and some aluminum or
steel fittings are for lower pressures. Be sure
that locally sourced fittings are rated for 7 MPa
(70 bar) operation.
We run a fixture for 3 months, store it for
6 months, then bring it back on line. How
can we keep everything working?
Preventive maintenance. Before you store
your fixtures, be sure that they are free of
coolants, coolant buildup, clean and dry. A light
coating of corrosion protection may help. Be sure
to store in a cool, dry, clean environment.
Our clamps are used for cast iron
grinding. Our coolants also seem to be
corrosive (our fixture plates rust). Will
your clamps stand up to this?
Nothing is going to be 100% foolproof. Our
extensive use of hard chrome plating, stainless
steel and our corrosion resistant BHC™
will give you the best possible resistance to
corrosion. Our processes will allow our clamps to
run longer with fewer problems even in this
destructive environment.
Preventive maintenance is essential to
keep hydraulic systems and components running
at peak performance through millions of cycles.
Be sure to flush your entire system at least
once a year and more frequently in high
contamination environments.
When I look at my clamps, there are
threaded holes in them. What do the
labels “P” “ADVANCE” “RETRACT” mean?
These threaded holes are called ports. The
label “P” or “ADVANCE” ports are normally used
to clamp the part, “RETRACT” indicates the port
normally used to unclamp or retract the clamp.
My local chemical representative has
recommended the use of “water-glycol”
hydraulic fluid. What are the benefits of
this fluid and should I use it?
Water-glycol is a non-traditional hydraulic
fluid. This fluid was developed for use where
petroleum based fluids are not allowed. They are
commonly used in areas requiring “flameproof”
fluid. They often cause problems with device
seals, valves and pumps. We do not recommend
water-glycol fluids. We may in some cases be
able to provide devices with seal compounds
acceptable for use in this environment.
How hot is too hot to run hydraulic fluid?
Anything above 177°C is considered too hot
for most hydraulic fluids and seals. Our standard
seals are rated to operate at temperatures from
4°C to 71°C. Even seals made of fluorocarbon are
not recommended above 177°C. For advice on
high heat applications, please contact Vektek’s
Engineering Department who stand ready to help.
I have my cylinder hooked up to a pump.
It extended but won’t retract. What have
I done wrong?
Is there a directional control valve in the
circuit? If not, one is required. Can you provide
a photo, schematic or simple hand sketch for us
to troubleshoot? We are glad to help.
How do I read my gauge and what
does it mean?
First, release all pressure on the system.
Check the gauge for proper operation. Check to be
sure that the gauge is returning to “zero”.
Pressurize the system and read the gauge. The
current reading from the gauge indicates the
pressure your clamping system operates at when
clamped unless there is a pressure limited circuit
branch. (The entire system equalizes at this
pressure, ∆ P is negligible when under static
clamping conditions.)
I need a clamp just like your
L1-4025-00L except it needs a 150 mm
long rod. Can you help me?
Maybe. We do entertain specials from time to
time. Please ask us. We often find that “special”
requests coincide with our ongoing new product
development. If you have a special need, it is
worth asking. We may decide to do your special
as a development project. We may not be able to
produce it (actually you may not want it) because
of cost. It may be something we have done before
and will be relatively easy.
The danger involved in using “specials” is
that we do not stock replacements on custom
parts. When your machine crashes (when, not if)
and you need a rush spare, custom parts have to
be made from scratch. You will need to order
spares at the time of the original order. The cost
of a single replacement on a complicated special
can often be 5-10 times the cost paid in the
beginning. A little foresight will be very beneficial
if you must have a special.
If you have questions you’d like answered,
call, write, fax or email us. We would
be glad to help you use VektorFlo®
products more effectively.

Fixture Building Tips
General Tips
When Manifold mounting VektorFlo
components, the mating surface must be
flat within 0.08 mm, with a maximum
surface roughness of 1.6 μm Ra for proper
sealing (unless otherwise noted in
the catalog).
■ Unless otherwise noted in our catalog,
VektorFlo® 7 MPa devices require a
minimum pressure of 1.0 MPa (10 bar)
■ Maximum system flow rate is 5.7 l/m
for all VektorFlo® special function valves,
unless noted otherwise. Excess flow
voids warranty.
■ De-burring of pockets or cavities is
extremely important to avoid leaks from
damaged seals.
■ Fluid filtration to catch chips will
prevent leaks and extend the life of
your components.
■ Preventive maintenance is essential to
keep hydraulic systems and components
running at peak performance through
millions of cycles. Be sure to flush
your entire system at least once a year
and more frequently in high
contamination environments.
■ To extend the life of your
hydraulic components:
®
■
* Hydraulic fluid should be changed and
the reservoir cleaned out annually
* If you operate a full production

Work Support Tips
Speed Control
■ Install with a six point socket only.
■Flow controls are often required to make
Other types of wrenches may damage
the work support.
Swing Clamp Tips
Never allow swing clamp arm to contact the
work piece during arm rotation.
■ Swing Restrictors are available in 30, 45
and 60 degree angles, Order from your
Vektek Sales Representative or Order
Entry Specialist. Other swing restricting
angles are available upon request as
a special.
■
Arms/Levers
■
When installing a swing clamp arm, restrict
the arm to prevent rotational torque to the
plunger and potential internal cam
damage. You may then tighten the locking
features to specification without damage
to your clamp.
Plumbing Tips
■ Use of standard rubber hoses and end
fittings can hamper the action of many
devices due to excessive end fitting
restrictions. If you choose to purchase hoses
locally, choose diameters and end fittings
that are not causing excessive restrictions.

swing clamps and work supports function at
appropriate speeds. Swing clamps may be
damaged by swinging large mass arms at
a greater distance from the clamp centerline
than recommended on the catalog pages.
Work supports may advance with speed
faster than expected, bounce off of the
intended part surface and become locked
before the spring can mechanically
re-extend them.
■In cases where speed control is necessary,
all workholding devices should be flow
controlled with “meter-in” devices like
our in-line or In-Port flow controls with
free-flow returns. Needle valves or
“meter-out” flow controls as are often used
in pneumatics should not be used to prevent
a pressure intensification which may occur
on “meter-out” hydraulic applications.

7 MPa Work Supports
Why do I need to use work supports?
B-1
The basics of 3-2-1 fixture building require
that three points define the plane of part
location. When machining, a floating location
support (work support) is an easy solution to a
part requiring additional support for more than
the three basic locators. You can use a work
support anywhere a "screw jack" can be used.
It adjusts faster, without distortion and without
dependence on the operator’s "feel".
A work support will provide solid adjustable
support for parts ranging from fragile circuit
boards to massive airplane spars, without
inducing distortion. They provide "automatic"
adjustment and lock-up giving repeatable,
predictable results without the risk of
"forgetting" a clamp or the time of manually
adjusted alternatives.
What is required to use work supports?
Work supports will work in most applications
where part distortion, chatter, ringing or poor
surface finish results are present. Work supports
can decrease most of the problems caused by
part movement during machining. All you need
to use them is an application, space to insert the
support, power supply and plumbing. They can
work wonders to improve part quality and reduce
scrap and rework. Work supports are often used
on fixtures where parts are manually clamped but
require support.
After the plunger is advanced, hydraulic
pressure engages a clamping mechanism which
locks the plunger and holds it securely against
the part. It then becomes a solid support holding
the part with the capacity indicated on the
appropriate chart (page B-2).
Can I use work supports without other
hydraulic clamps?
Yes, work supports are often used when
manual clamps are used. They reduce the
dependence on "operator feel," speed operations
by locking multiples with a single adjustment
and speed load time dramatically even when
used with manual clamps to secure the part. In
fact, one of Vektek’s most effective applications
was one where the part was bolted in place over
a tower equipped with several work supports.
They supported the inside of a case while the
outside was being machined. Our work supports
reduced the part loading time from over five
hours to just under one hour in this application.
Explain the difference in the two advance
types and why I might want to use one
over the other.
Spring advance is typically used when the
part is heavy enough to depress the spring loaded
plungers. This can be used on most applications.
Fluid advance is used to prevent interference
during part load and insures part is properly
seated before clamping.
What is the "breather port" and can I
plug it or use it for my
hydraulic connection?
All 7 MPa work supports require the exchange
of air. They will work consistently when allowed
to exchange air to and from the atmosphere.
What type of part will typically need
work supports? Are there any I
should avoid?
Parts with thin webs, unusual shapes or
unsupported structures that must be held within
a plane are likely candidates for work supports.
There are no parts to be avoided. Cast iron and
aluminum parts produce large quantities of fines
that can infiltrate cavities and reduce work
support life.
What about deflection?
Deflection is based on Elastic Deformation
of materials when loads are applied. All
material elastically deforms and it is important
to understand that this deflection is not caused
by the support slipping or failing. Vektek work
supports are designed with selected materials
to minimize elastic deformation. Other factors
that may affect deflection include: Surface
finish, material and contact area of part being
supported. In cases were special contact bolts
are made, it is important to understand how
the shape of the contact surface along with
the material selected will affect deflection.
Deformation values advertised are based on
Vektek contact bolts only.
1-800-992-0236
Can I lay my work support on its side?
Normally, yes. As long as you are not using
a heavy end effector or unusually side loading
your support, the physical orientation should not
affect performance. If you have a question about
a specific application, please give us a call.
I have an interrupted cut that is going to
take place over the top of a work support.
The forces involved are transmitted
directly down on the support. The cutter
is a large straddle milling cutter and
the cut is interrupted because I am
sawing through webs on a cast part. How
do I size the work support for
this application?
Work Support capacities shown in provided
charts and formulas are based on static loading.
Because of unknown variables (examples: dull
tool factors; mild hydraulic pressure fluctuation;
cutter vibrations; etc.) work supports selection
should be made so that the capacity at specified
pressure is a minimum of 1.5 times the sum of
applied clamping force and machining force.
Interrupted machining cuts and pressure spikes
can apply severe dynamic loading to the work
supports. In cases where dynamic loading is
present you should use a support capacity
minimum of 2 times the sum of applied clamping
force and machining force.
Do I need to use a torque wrench and
socket when installing cartridge work
supports?
Yes, a torque wrench and a 6 point socket
is required. If you use an open end, adjustable
or box end wrench you increase the chances
of damaging the work support. Please use an
appropriate socket, torque wrench and care
when installing cartridge work supports.

Spring extended plungers maintain contact with the part
during loading, exerting only spring force against the part.
When hydraulic pressure is applied the plunger “freezes’ without
exerting any additional force on the part.
If spring advance supports are used in flood coolant
environments, vent to clean dry air.
Top Flange minimizes the distance from mounting surface to

Available in four capacities from 3.0 kN to 10 kN.
Normally retracted plungers do not interfere with part loading.
Advance them with hydraulic pressure, exerting only spring force to bring
plunger into contact with the part. Hydraulic pressure then automatically
sequences, “freezing” the plunger properly against the part.
Choose between a High-Tension or Low-Tension Spring to fit your application
Plumb through BSPP ports or manifold mount. Optional flow control requires
the use of manifold mount portys,
“Floating” locator that doesn't interfere with 3-2-1 locating principles.
Only spring force is applied to the part. Hydraulic actuation freezes the
plunger without exerting any additional force on the part.
 Minimal friction wiper design keeps chips and debris out while
providing smooth plunger action.
 In-Port flow control valves can be used to control the plunger advance
rate on support useng manifold mount hydraulics.
Optional In-Port flow control is a meter-in device with reverse free flow
check valve.

 Link Clamps , Swing Clamps, and Work
Supports are designed to work as
a system.
 Clamps and Work Supports work together
at the same pressure.
 Sequencing is required and must occur
above 2.5 MPa.
 Clamps do not need pressure reduction
when clamping over a work support and
operating in the range of 4 to 7 MPa.
This applies even when Vektek extended
arms are used.
Off the shelf Swing Clamp arms and Link
Clamp levers designed to the correct length
for clamping over work support centerline.
Swing Clamp arms can be found on page D-2

TuffCam™ 7 MPa Swing Clamps
C-1
When do you recommend the use of
TuffCam™ 7 MPa Swing Clamps over other
Vektek product?
Sometimes there are applications where
speed is essential. Sometimes size and weight
are critical. Often an available power supply
limits pressure available.
What kind of return on my investment can I
reasonably expect by converting my manual
clamps to TuffCam™ 7 MPa Swing Clamps?
Ask your Vektek sales representative for the
Power Workholding Brochure. Time studies and
costs are comparable justification.
What makes the cam follower ball seat so
special in these units?
The three cams and three cam balls guide
the rotation of the plunger and provide greater
guide, support and directional stability. The
patented cam follower design is unique in the
industry and uses solid tungsten carbide balls
and stainless steel ball seats. The ball seat
design assures that the ball rolls in the cam
rather than jamming and scraping resulting in
wear on both the cam track and ball. This vastly
improves swing repeatability, contacting the
same point ±0.25 degrees.
I want to use work supports with TuffCam™
7 MPa Swing Clamps. Can you give me some
tips that will help me get the most from my
clamping devices?
Vektek 7 MPa Work Supports and Swing
Clamps are made in capacity sets as well as
arm-to-support centerline measurement.
It is important to hit my part
in the exact place every time in my
application. Will your TuffCam™ 7 MPa
Swing Clamps meet this requirement ?
Standardized repeatability of ±0.25
degrees is "Best-In-Class" Worldwide.
What defines a TuffCam™ 7 MPa
Swing Clamp?
TuffCam™ 7 MPa is a single direction
tri-cam design swing clamp. These clamps
produce the strength and reliability to support
faster speeds and larger arms. TuffCam™ 7 MPa
delivers notably better accuracy and repeatability
over other brands. The clocking feature,
dramatically reduces the time it takes to
change arms for maintenance, replacement
or design set up.
How can I measure the clamp speed?
The maximum speed of a swing clamp is
applicable to both clamp and unclamp function,
as the momentum on the cam track and cam
follower apply to both movements. To
approximate the speed of your application:
* Look down the centerline of the swing
clamp, perpendicular to the arm.
* Actuate your clamping system while
watching the arm “swing” into position.
* If while looking directly into the end of
the swing clamp, you can observe the
arm move through its swing, the
positioning time should be somewhere
around ½ second or longer. See flow
rates and clamping time in page C-2
* If, while looking directly into the end of
the swing clamp, you cannot observe
the arm move, or it is unclamped and
the next thing you can see is that it in
the clamped position, the positioning
time is something substantially less than
1/2 second. Your standard model clamp
is at risk of premature failure. See flow
rates and clamping time in page C-2
* It is possible to approximate the clamp
time by adding the total active volume
of devices in the specific control branch
of your system, and dividing that volume
(cubic mm) by your pump’s output
volume (cubic mm per minute) and
then multiplying that number by 60
(60 seconds per minute). This will give
you the theoretical calculated time to
move a device through its stroke, but does
not account for flow loss due to flow
restrictions in the system.
I want to use the jam nut only to hold my
arm in place. Will this work?
It is unlikely that you can use the jam nut to
hold arm orientation adequately. We have had
customers modify clamps to include flats, pins,
serrations or use set screws to hold orientation.
These methods may work in specific instances.
We still recommend our method of attachment,
locknut and cross bolt for a secure, dependable,
universal attachment. Other methods may
complicate the replacement of clamps when
they are damaged by a machine crash or
other problems.
Why should I buy your arm rather than have
my toolmaker make one?
Our arm is designed to hold orientation
when properly installed. It has a relief to keep
from over-stressing the locknut. It will probably
cost you less than the total cost of making your
own. You can rest assured that our arm is made
to our specifications and will withstand the
forces our clamps generate, when used
as recommended.
I need an arm slightly different from those
you make. Can I make or modify your arms?
Our first recommendation is to modifying our
existing arms if possible. All VektorFlo® arms are
able to be machined or welded. You should be
able to easily modify any standard arm you
purchase. We recommend this because our
original design for the cross bolt orientation
mechanism is the most secure, dependable and
versatile orientation method available. Many
customers and competitors have tried to copy it,
some with limited success.
If you desire to make your own arm(s), refer
to the detailed information on page D-3. Please
be sure to put in the 0.5 mm step for the locknut
and relieve the cut in the arm so that the bolt
will squeeze the plunger shaft. If you do not take
these two steps, your custom arm may not
work satisfactorily.
NOTE: See Arm Length and Pressure Limitation Graphs on Page D-5.

TuffCam™ 7 MPa Swing Clamp
TuffCam™ 7 MPa Swing Clamps were developed to meet your
demand for high-speed, precise positioning and/or heavy arm
applications in a 7 MPa operating pressure environment. One of the keys
to this innovation is the patented spring loaded TuffCam™ design that
was developed to improve strength and wear. Using the patented Vektek
V-Groove, a stainless steel ball seat, these clamps have reduced static
friction for improved clamp breakaway and reduced dynamic friction for
improved life. This combination adds up to producing the most accurate and
repeatable swing clamp cam assembly.
Available in 6 sizes from 1.9 kN to 20.4 kN at 7 MPa (70 bar),
in Top Flange and Bottom Flange body styles.
Double acting
 Three cams for more accurate arm positioning (90° ± 3° swing
accuracy) (±0.25° contact position repeatability)
7 MPa swing clamps are designed to work at any pressure between
1 MPa (10 bar) and 7 MPa (70 bar) using either the standard or
extended length arms without the need for pressure reduction.
 Patented ball seat for improved rotary function, cam follower contact,
and reduced dynamic and static friction.
Tungsten Carbide balls 
BHC™ (Black Hard Coating) on the cylinder bodies helps prevent
scoring and scratching.
 Clocking features help to improve and speed-up arm changes.

The above flows are maximum recommendations and clamp times are minimum recommendations.
- When using custom arms the extended arm flows and times are to be
considered the limiting factor.
- The actual time to position the clamp will vary by custom arm configuration. Excess weights
may require slower speeds and customer testing in specific application to establish limits.

*
Cylinder capacities are listed at 7 MPa (70 bar) operating pressure, with a standard length VektorFlo® 7 MPa arm installed. Maximum operating
pressure is 10 MPa (100 bar). The minimum operating pressure is 1 MPa (10 bar). The clamping force is adjustable by varying the hydraulic system
pressure. To determine the approximate output force for your application, divide the cylinder capacity shown above by 7 MPa (70 bar), and multiply
the resultant number by your system operating pressure MPa (bar) to obtain the approximate clamping force for your application. (Actual force will
vary slightly due to internal cantilever loading, and/or friction loss.)
**
To allow for piece part height variations, it is recommended that the vertical travel be set to about 50% of the vertical stroke.
*** To ensure maximum service life and trouble-free operation, restrict fluid flow per table on page C-2.
**** In-Port flow control requires the use of manifold mount port.

Cylinder retract capacities are listed at 7 MPa (70 bar) operating pressure. Divide cylinder retract force by 2 for when using symetrical length arm.
Maximum operating pressure is 10 MPa (100 bar). The minimum operating pressure is 1 MPa (10 bar). The clamping force is adjustable by
varying the hydraulic system pressure. To determine the approximate output force for your application, divide the cylinder capacity shown
above by 7 MPa (70 bar), and multiply the resultant number by your system operating pressure MPa (bar) to obtain the approximate retract force
for your application. (Actual force will vary slightly due to internal loading, and/or friction loss.)

TuffCam™ 7 MPa Arm Clocking Feature
C-11
The 3 divots or "Clocking Features", located on the plunger, help arm installation in
repeat fixture applications and with arm changes when maintaining fixtures. Installing a
set screw into the arm properly positions the arm relative to the plunger and swing clamp
body. The 3 divots are located at 120° intervals around the plunger to assure access to at
least one in any body-arm orientation. Vektek swing clamp arms are made with clearance
to allow the drilling and installation of set screws according to this drawing.

TuffCam™ 7 MPa Swing Clamp Arms
I need to make my own arms, what
information do I need?
The information that you need is detailed
on page D-3. We strongly encourage you to
copy our connection to the swing clamp rod.
The combination of the top locknut and side
bolt squeezing action is the most secure
connection on the market today. You should be
sure to put the 0.5 mm step in your custom
arms for best results.
Can I modify the arms I buy from you?
Yes, you can. Our arms are made of a cast
alloy steel that you can easily weld or machine
to fit your needs.
Why should I buy your arm rather than
have my toolmaker make one?
Our arm is designed to hold orientation
when properly installed. It has a relief to
keep from over-stressing the locknut. It will
probably cost you less than the total cost of
making your own. You can rest assured that
our arm is made to our specifications and will
withstand the forces our clamps generate, when
used as recommended.
Vektek arms also include an area to add
clocking set screws making arm changes faster
and more accurate.
I need an arm slightly different from those
you make. How do I make my own?
Our first recommendation is to investigate

All VektorFlo® arms are machinable and
Yes, you should. The step in top of the
arm relieves stress on the locknut and the piston weldable. You should be able to easily modify

capacity rating for this clamp is 9.4 kN. If you
are pulling in the center of the arm and both
points are being contacted at the same time,
divide the force by 2 (two).
www.vektek.com
1-800-992-0236
I want to clamp two parts, with each double
ended swing clamp arm. Do I need a fixed
or pivoting arm?
If your parts will not vary in size (clamped
height) you can probably get by with a fixed
clamp arm. If your parts vary by as little as
0.1 mm you may get significant variations in
clamp force with a fixed arm (higher force on
the taller part, lighter force on the shorter one).
If your parts vary or the clamp force is crucial,
we recommend a pivoting arm so that the force
is equalized on both parts. (Remember, if the
length varies, the resulting forces may change.
Be sure that both ends are equal length.)
Do you have a way to "quick change" my
clamp arms?
The Clocking Features, located on the
plunger, help arm installation in repeat fixture
applications and with arm changes when
maintaining fixtures. Installing a set screw into
the arm properly positions the arm relative to
the plunger and swing clamp body. Vektek swing
clamp arms are made with clearance to allow
the drilling and installation of set screws. See
page C-11.
I have a number of parts to clamp with
my swing clamp fixture. The parts are of
different heights. Do you have an easy way
to alter the clamp arms to make them work
for all heights?
You will need to make a custom
attachment. Set your swing clamp to be able
to clamp the tallest part with the standard arm.
The height or width can then be adjusted by
attaching a contact device to the arm. You might
also want to consider the clevis clamp for minor
variations in height

How to Use the Clamping Force Tables
1) Start by choosing the arm length you need for your application.
• The tables and graphs show the relationship between arm length,
operating pressure and clamping force.
2) Then move along the line and select the clamping force and operating
pressure or operating pressure and clamping force needed.
• The arm lengths shown in parentheses (page D-5) are the usable length from
the edge of the clamp body to the contact bolt.
Example: Using a L1-4X25-00 with a 30 mm arm;
the clamping force would be 1.4 kN at 5.0 MPa

• Tables include maximum operating pressure
associated with the arm length shown in
the header rows of the table.
• The column on the right of the table is
the maximum arm length allowed at the
associated operating pressure.
• Operating the clamp in the
non-usable range will damage the
clamp and void product warranty.

Link Clamps
The link clamp arm pivots up and out of the way to accommodate
hard-to-reach or hard-to-hit clamping points. Link clamps contain the beam
mechanism often preferred by fixture builders. This self-contained beam
eliminates the need to build or design a clamp mechanism as part of the
fixture. Vektek‘s unique body and pivot design provides the least side-to-side
axial deflection and the most rigid product on the market today.
The new TuffLink™ 360° is outfitted with a rotary lug to provide
full rotational positioning of the lever. Compare the flexibility of
TuffLink™360° to others on the market that provide limited positioning.
What benefit does the rotary lug offer?
E-1
The rotary lug on TuffLink™ 360° allows the clamping lever to
be positioned anywhere, 360˚ around the mounting flange. This feature
helps in the design phase of a fixture by simplifying feed hole drilling when
manifold mounting. The body can be rotated into optimal alignment with
drilled passages. Just rotate the body so the manifold mount ports align
with deep drilled feed holes. This feature also saves time and money after
the fixture is built by allowing greater flexibility for last minute adjustments
in work piece design or casting variations.
How is the rotary lug better than the eccentric levers
offered by the competition?
Never derate a Link Clamp again due to an offset lever design. The
clamp lever can now be rotated to adjust for part changes or last minute
variations. Because it maintains symmetric loading on levers, pivots
and pins, clamp life is vastly improved and failures eliminated.
Patent Number
8,678,362
When should I use a TuffLink™ 360° clamp?
A TuffLink™ 360° clamp is often preferred when you must reach over,
not swing over or around a height obstacle and need full lever rotation to
set points. Reaching down into a die casting, between two mounting lugs,
or a direct overhead vertical load are good examples where these devices
are required. Keep in mind that the vertical clearance must be greater when
you are bringing a part into position, but direct drop-in loading is easily
accomplished by an operator or robot.
What is the vertical stroke of a TuffLink™ 360° clamp?
The maximum part variation is included in the vertical stroke. When
outside the vertical stroke specification, the force generated by the clamp
will be reduced and may result in reduced clamp life. You will find vertical
stroke specifications on Page E-2.

Rotary Lug
How do I adjust the position of the rotary lug?
When should I avoid using a link clamp?
Others
If you are clamping on a draft angle, the angle will exert undue
stresses on the linkage mechanism. Make sure the clamp mounting flange
and lever are parallel to the clamping surface. This will ensure linkages are
not over stressed. Avoid stressing guidance mechanisms of either swing
clamps or link clamps as these stresses will cause premature failure not
covered by warranty due to misapplication. The drawing below will help
you handle clamping on a draft angle.
Rotary adjustment is easy, just loosen the two set screws near the
pivot on the rotary lug. Use a wrench on the end of the lever to rotate lever
to desired orientation and torque set screws.

Clamp capacities are listed at 7MPa (70 bar) operating pressure with a standard length 7MPa link clamp lever installed. Use of an
extended length lever will result in a reduction of clamp force. See section "F", for the clamping force of various lever
lengths and pressures. The force is adjustable by varying the hydraulic system pressure.
**
To insure maximum service life and trouble-free operation, restrict fluid flow to the above flow ratings. If you are unable to measure
flow rates, these devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever.
When using the optional extended lever or your custom lever, please restrict the flow rates to position the lever in no less than 1 second.
*** Equal to +/- 3˚ with standard lever
NOTE: Maximum operating pressure is 10 MPa (100 bar)
Minimum operating pressure is 1 MPa (10 bar)

* Cylinder capacities are listed at 7 MPa (70 bar) maximum operating pressure. Minimum operating pressure is 1 MPa (10 bar). The output
force is adjustable by varying hydraulic system pressure. To determine the approximate output force for your application, multiply the Piston
Area times Your System Operating Pressure. Actual force may vary slightly due to friction loss, seal and wiper drag.

Operation: The VektorFlo® Unclamp Delay Valve
operates as a normally open element in an
hydraulic clamping system. Low pressure
fluid flows freely through the valve to
downstream devices. As pressure in the
system builds, the mechanical pilot piston
moves away from the check valve allowing it
to close. Full system pressure is reached and
flow in the system stops. If pressure leaks off
in downstream devices, the check valve will
re-open and replenish pressure. During
unclamping, inlet pressures falls with main
system pressure but downstream pressure is
held constant by the check valve. At the low
inlet pressure, spring force starts to move the
mechanical pilot towards the check valve at
a rate set by the flow control and oil
viscosity. The mechanical pilot piston moves
through its stroke and encounters the check
valve. Spring force opens the check to
release all downstream pressure to the
power unit reservoir.

Sequence Valve
Sequence Valve for Circuit Timing
100% stainless steel valve. Construction resists corrosion
which can cause other styles to "misfire".
Direct acting poppet style, adjustable, cartridge type construction.
Cartridge may be installed directly into your manifold.
Set Pressure adjustment range: 2.0 MPa (20 bar) to 6.2 MPa (62 bar).
Two-port design eliminates need for third fluid line to drain bypass
flow (internal leakage) back to system reservoir.
True sequence design allows full system pressure downstream
of valve after opening.
Up to 10 MPa (100 bar) system pressure.
Recommended Filtration: 25 Micron (Nom)/ 40 Micron (ABS) (min).
 We recommend a 1 - 1.5 MPa (10 -15 bar) spread between
pressures when using multiple valves.
Operation: The VektorFlo® sequence valve operates as a pressure
sensitive, normally closed element in a clamping system.
When fluid first enters the system, the valve is closed,
blocking the flow of fluid to devices downstream. After
devices upstream of the valve have moved into position
and pressure begins to increase, the increasing pressure
overcomes the spring force holding the valve closed,
forcing the poppet off its seat, and allowing fluid flow
through the valve. After downstream devices have
positioned and clamped, and downstream pressure has
increased to equal upstream pressure, entire system
pressure increases to the maximum level setting on the
hydraulic power supply. When unclamping, as pressure
falls, force from the adjustment spring pushes the
poppet back onto its seat. Fluid trapped in the
downstream circuit flows back through the check
valve to return to the power unit reservoir.

Description
Set Pressure Range
System Pressure
Operation: The Pressure Reducing Valve (PRV) is a Normally Open (N/O)
pressure control device. The valve remains open and fluid flows
freely to downstream devices (from the valve to devices) until
the pressure in the valve reaches the pressure (adjustable)
set-point. At the set-point pressure, the valve closes blocking

further flow and pressure rise to the downstream devices. If there
5,931,182
is a sufficient down stream pressure loss (from the valve to
devices), the PRV will re-open, allowing flow to pass through the
valve until the pressure again reaches the valve set-point. The
PRV is designed for use in both single-acting and
double-acting systems.

Safety
Safety First & Always
No power workholding catalog would
be complete without a few words about
safety. Hydraulic clamping can provide
significant safety advantages over manual
clamping. But carelessness in planning or
operation can injure workers and damage
expensive equipment. So take a positive
approach. From the planning stage to the
work schedule, think and practice safety.
Like other mechanical devices, the use
of hydraulic workholding devices is subject
to certain hazards that cannot be
precluded by mechanical means, but only
by the exercise of intelligence, care, and
common sense. It is therefore essential to
have personnel involved in the use and
operation of equipment who are careful,
competent, trained and qualified in the
safe operation of the equipment. Some
examples of hazards include but are not
limited to: inadequate clamping capacity;
unprotected pinch points; hoses, tubing
and fittings not rated for system working
pressures; improper installation and
maintenance; and inadequate system
monitoring.
As with all clamping devices, these
clamps have pinch points. Secondary pinch
points also exist in some devices such as
swing clamps, because of their rotation,
and other clamps which may be used with
extensions. If any of these conditions exist,
personal injury may result from crushing
action, flying projectiles and burst tubing.
These same actions may also result in
destruction of property.
Assemble and install
equipment with care.
Even minor leaks from high pressure
hydraulics can be dangerous. An
improperly secured component can become
a projectile. Don’t "build in" hazards by
careless installation of your hydraulic
clamping system.
Route tubing and hose where they
won’t be exposed to damage. Make sure
that connections are tight and properly
made. Avoid unsupported straight tubing
runs. Use large radius bends to facilitate
assembly and allow for expansion and
contraction. Align fittings carefully so that
connections do not introduce stress.
See that threads are fully engaged
on mountings and brackets. Make sure
that stops are adequate to withstand the
clamping forces that may be developed.
Test the system before starting production.
Keep your operators thinking.
With your system on line and in
production, set up and enforce work rules
that help avoid human injury and damage
to equipment. Be sure every operator
knows his equipment and develops good
work habits. An operator should always
make sure valves are in the correct
position before he starts a hydraulic pump.
Keep hands clear during clamping
operations. And use judgment in
positioning the work piece. Be sure the
work piece is properly positioned before
clamping forces are applied. Watch for
Plan with safety in mind.
kinked hoses. Monitor gauges to see that

workholding equipment. Position valves,
safety guards and controls with the
Caution: Be sure to keep clear of

components are compatible and adequate
to perform their respective functions.

Follow good maintenance practices.
A clean, well-cared-for workplace is a
safer workplace. Make daily inspections for
damaged hose, bent tubing and leaks.
Repair or replace anything that shows
signs of wear or damage before minor
problems become big ones.
We design and build your components
with durability, performance, and safety in
mind. Properly selected, installed and
maintained, they will serve you long
and well. The best hydraulic components
embodied in properly designed circuitry
can be expected to perform properly only if
it is thoroughly cleaned before it is
activated. Dirt is the number one enemy
of hydraulics!
As an integral part of system design,
care must be taken to select the proper
devices and accessories ensuring proper
integration with your operations and
equipment. Sufficient safety measures
must be taken to avoid the risk of personal
injury and property damage from your
application or system.
Vektek, Inc. cannot be responsible for
injury or damage caused by unsafe use,
maintenance or application of its products.
Please write the Vektek office including
specifics for guidance when you are in
doubt as to proper safety precautions
regarding design, installation or operation
in your particular application.
