Designing Your Own Hydraulic System
1. Calculate the force used to hold the workpiece during machining.
To convert the torque applied to a fastener into holding force use the following formula:
P= T
KD
P = Holding Force (kN)
T = Torque (N.m)
D = Nominal Thread Diameter (mm)
K = Friction Factor
(K Varies with material, finish, and lubrication, .19 to .25)
Where:
Example: M12 bolt tightened to 50 N.m
P=
50
(0.22 x 12)
= 19 kN
2. Calculate the force required at each work unit.
Total Force
= Force per unit
Number of work units
3. Select the style of work unit to be used at each location. Select units which can be easily mounted and will allow
access for loading and unloading of the workpiece.
4. Compare the force required by each work unit with the maximum force available from the unit selected. If the required
force is greater than the available force, substitute larger work units or increase the number of work units to be used.
5. Calculate the hydraulic pressure required to provide the force needed at each work unit. To determine pressure,
divide the force required at the work unit by the effective piston area of the unit selected.
Force = Pressure
Area
The unit requiring the highest pressure determines the requirement for the entire system.
6. Determine the total volume of oil required to operate all of the work units (Volume = Piston Area x Stroke).
Operating volume requirements for work units are listed in the specifications chart for the item.
7. Select a power source which will provide the required pressure, using the available air pressure. To determine if a
power source will provide the required pressure from available air pressure, multiply the available air pressure by the
boost ratio of the power source.
Example: (5 bar air pressure) (15:1 boost ratio) = 75 bar hydraulic pressure
The power source must also provide the total volume of oil required by the system. When using a standard booster,
the high pressure volume of the unit must exceed the system requirement.

Swing Cylinder - Application Information
• Arm length can effect clamping pressure - See Chart and Data
• Weight should be considered when utilizing modified or special
arms, other than those provided by Jergens.
• Speed of operation is a major consideration. All swing cylinders
MUST BE USED WITH FLOW LIMIT VALVES to dampen
the rotation action.
• Care should be used when select Hydraulic Accessories be aware of maximum operating pressures.

These versatile swing cylinders/clamps can be
used as single or double acting rotating clamps,
or push/pull cylinders. The piston in the Swing
Cylinders rotate 90° to the right, but may easily be
changed to 90° left rotation, or to no rotation at all.
WARNING: All swing cylinders must be used with
flow limit valves (page 14, 74) to dampen the
rotating action. Please see maximum flow rate
shown below.
• Can be mounted using four #10 cap screws or the 1"-12 thread on the
O.D. of the cylinder
• Optional components include the threaded mounting bracket and jam
nut shown below
• Can be used as a non-rotating clamp
• Maximum recommended flow rate is 20 cubic inches (330 cm3) per
minute per clamp (approximately 1 second clamp time)

Boring Mill Application
The I.D. of the casting is located with a pilot locator on its vertical face. The
Retracting Clamps move into a clamping position between the ribs in the
casting. When it is time to change parts, the clamps retract out of the way for
easier part removal. Jergens Swing Clamps or Swing Cylinders could also
be used in this application.

Hydraulically-locked Work Supports differ from clamps and
vises in that they do not actually exert force upon the workpiece.
Rather, they are used to support the part being machined,
offering resistance to any clamping forces acting counter to the
direction of travel of the piston.
In a typical application, a large, thin casting is located on
several tooling point pads for positioning. Work Supports will
automatically adjust to support the delicate sections of the
casting. When hydraulic pressure is applied, the floating pistons
within the Work Support are locked in position and resist any
downward movement exerted on the casting. After the casting is
removed, the floating pistons return to their fully-raised position.

Work Support
Applications
The workpiece is located and clamped on the right end by a Jergens Swing
Clamp. The Work Support resists the machining forces applied to the other end
of the casting. Variations between castings are compensated for by the floating
support plunger in the Work Support.
The top and bottom surfaces of the large casting must be machined to be
flat, parallel, and at a fixed distance from each other. Jergens Work Supports
eliminate deflection at the outer edge while compensating for variations
between castings. A Jergens Hollow Rod Cylinder, stud and “C” washer
are used to hold the casting.
21
Hydraulic Cylinders
www.jergensinc.com
Hollow Rod Cylinders
Hollow Rod Cylinders are ideal
for converting existing fixtures
to power clamping. Replaces
clamps which use double cams,
flange nuts, draw bars, or other
mechanical devices. Generally,
no special machining is required,
just a longer stud.

Hollow Rod Cylinder
Applications
Typical, low cost conversion from manual clamping to Hollow Rod
Cylinders can be accomplished by using the existing drill jig clamps
and changing the stud to a longer length. Besides clamping faster
than the manual method, the Hollow Rod Cylinders allow for uniform
clamping forces on all strap clamps.
The Hollow Rod Cylinder is ideal for “close
to the machine base” strap clamping. By
mounting the clamps under the work table,
a manual clamping set-up can be easily
and economically converted to hydraulic
clamping.

Jergens Pressure Points may be used with any power source and are designed to be
used in restricted areas where space is at a minimum. Pressure Points can be used to
eliminate part distortion during machining operations or to hold large diameter castings
or rings in place while machining the upper surface. Pressure Points have hardened tool
steel tips (50-60Rc). Jam nuts are included. Not suitable for air operation.

Threaded Cylinder
Applications
By replacing step blocks
or similar mechanical
devices with a threaded
cylinder, manual clamping
is easily adaptable into a
more productive hydraulic
clamping set-up.
This principle of “building block” components can be combined with various Jergens cylinders,
standard components and mounting blocks or strap clamps; thus allowing an almost infinite
method of production clamping.
28
Hydraulic Cylinders
www.jergensinc.com
Standard Cylinders
Single Acting
These single-acting, spring-return cylinders will operate on
air or oil; all have a 1" (25.4 mm) stroke.
Specifications (Inch)
Single-acting cylinders are especially applicable to large circuits where
cylinders are plumbed into the air side of the circuit and used to align
parts in the fixture prior to hydraulic clamping. These applications are
primarily pushing type operations where the cylinder return spring pulls
only the piston rod.
NOTE: Not recommended for applications where coolant
or chips are prevalent. Use double acting style
(next page) for these applications

Double Acting
Port
Metric:3/8-19 BSPT
Inch:9/16-18
Double Acting Cylinders can be used for clamping, holding positioning, staking, punching...anywhere that a heavy duty
cylinder is needed. If the cylinder is mounted in the fixture (as opposed to using mounting brackets), the fixture should be
bored to between .0005 and .0010 over the “A” dimension. Doing so will prevent an out-of-round condition of the cylinder body
which could damage the piston. They may be clamped and/or returned by air or by hydraulic pressure.

Mounting Brackets are designed to save you time and money
when laying out your fixture.
Mounting Brackets
All Mounting Brackets are made of low carbon steel, which is not
heat-treated. This allows you to custom fit or weld the brackets
into your fixture. The cylinder clamping area is concentric to the
OD of the various cylinders to avoid distortion of the cylinder
walls which may cause damage to the piston.
Spacers may be used to add height to the cylinders when using
Jergens Mounting Brackets.

Intensifier Cylinders
Intensifier Cylinders are combination air-hydraulic cylinders. An air
powered cylinder is driven into a small oil reservoir which produces a
nominal 8:1 or 30:1 power boost ratio, depending upon air pressure
and the cylinder used. These miniature, self-contained power sources
are ideal where fast action (100 operations per minute), a short stroke
and high power are needed.

Intensifier Cylinder
Applications
Positioning
A series of plates are gang loaded into the fixture.
Air operation of the intensifier assures fast and
positive positioning of the plates, after which the
multiple hydraulic cylinders are used to clamp.
Clamping
Installed in a Jergens Mounting Bracket, the
Intensifier Cylinder provides efficient, versatile,
yet economical clamping.
Crimping
The intensifiers may be installed at any
attitude. Mounted in a vertical attitude
(as shown), up to 1.5 tons (15kN) of force is
available for crimping, punching, or notching.
Circuit Diagrams
A filter/regulator and a 3-way hand valve are all
that is required to control an Intensifier Cylinder.
Installation is as simple as an air cylinder but the
resulting force is much greater.

Staylock Clamps
www.jergensinc.com
Stays Mechanically Locked–
Even When Disconnected
from Hydraulic Pressure
StayLock Swing Clamp on a
Tombstone Fixture
The Swing Clamp rotates 80
° away from the workpiece,
allowing easy loading and
unloading of the part. In this
application, the tombstone is
mounted on a double pallet
machining center. When the
pallet rotates, the StayLock
Clamp remains clamped. There
is no need for an accumulator
in the hydraulic system. Nor
is there a chance of hydraulic
hoses getting tangled or
accidentally cut while the part
is being machined. StayLock
Swing Clamps are available
in left-hand or right-hand
swing styles.
StayLock Clamps ...the Hydraulic
clamp with the mechanical advantage!
With conventional power clamping,
when pressure is put to the clamp, it
clamps...take the pressure away (on
purpose or not), it unclamps. With the
StayLock Clamp's patented internal
locking mechanism, hydraulic pressure is
needed to clamp...and to unclamp!
StayLock Rocker Clamp
Holding a Die
The Rocker Clamp is ideal for
quick change clamping on dies,
molds, and fixture plates where
a standard height subplate
is employed. Because of the
unique body design of the
Rocker Clamp, it can easily
be adapted with a T-slot nut
mounted on the bottom. This
enables the Rocker Clamp to
slide in and out, making part
removal easier, plus it allows
for various widths of subplates
or fixture plates to be used.
StayLock Block Clamp on a
Tombstone
The Block Clamp is a multipurpose utility clamp, utilized,
as any StayLock Clamp can
be, in either the horizontal or
vertical clamping positions.
In this application, the Block
Clamp (at the top of the
tombstone) is replacing step
blocks and tedious manual
clamping.

Positive Mechanical Lock
Most Commonly Asked Questions
Jergens StayLock Clamps offer a breakthrough in clamping
flexibility! These mechanically locked clamps are activated
and released by hydraulic pressure. Once activated, the
clamps automatically lock and will not release until hydraulic
pressure is applied to the release port.
Q. Does the StayLock Clamp lose pressure?
Once clamped, you can:
• disconnect your hydraulic power source
• move the fixture, with the part still clamped, to other machines
• not worry about your part unclamping due to hydraulic power
failure, a cut line, or leaks in the hydraulic system
Patented positive mechanical lock minimizes:
• reclamping
• set-up costs
• parts accidentally becoming unclamped
A. No, it does not. Because of a patented mechanical lock, a
positive locking wedge is activated when pressure is applied
to the clamp port. There is no need to maintain hydraulic
pressure; therefore, the power source can be disconnected.
There is no pressure to lose.
Q. How do I lock StayLock Clamps in place?
A. Applying hydraulic pressure to the clamp port of a StayLock
Clamp drives two internal wedges together. The two wedges
form a mechanical lock and will not retract until hydraulic
pressure is applied to the release port.
Q. Can these clamps be used with air?
A. No. Air pressure does not apply enough force to lock or
unlock the internal wedge mechanism.
Jergens StayLock Clamps can provide solutions to many
clamping problems. They are designed for use on:
• palletized fixtures
• transfer machines
• machining centers
• any power clamping application
• quick change on molds and dies
Q. How much hydraulic pressure is needed to activate the
clamps?
Use the StayLock Clamps with Jergens Air-Operated Hydraulic
Pumps (described on page 63, 64, 65). One Hydraulic Pump
can service several machines because there is no need to
maintain hydraulic pressure when clamping StayLock Clamps.
Once StayLock Clamps are in a clamping position, the hydraulic
hoses can be disconnected, and the part will remain clamped
indefinitely. Once the machining cycle is completed, applying
hydraulic pressure to the release port unclamps the part.
A. Typically, a system includes several clamps (depending
on individual requirements); a power source; a four-way,
three-position, zero-leakage control valve (see page 66);
and hydraulic hose and fittings. There is no need for an
accumulator in the system.

A. The minimum pressure required on most of the StayLock Clamps
is 34.5bar. The minimum and maximum pressure requirements
are specified for each clamp on the following pages.
Q. What is needed to set up a hydraulic system using
StayLock Clamps?
Q. Can an air/oil booster be used with StayLock Clamps?
A. No. Boosters typically are used with standard hydraulic
clamps because pressure is needed to activate and
maintain the clamp in the clamping position. With a
Booster set-up, there is only one hydraulic line that provides
the pressure needed. StayLock Clamps need pressure to
clamp and unclamp; therefore, a Booster would not provide
the needed pressure to the release port to unclamp the part.
Q. Can I get technical assistance from Jergens when
designing a StayLock Clamping system?
A. Yes. Jergens will assist you by providing a CAD schematic
drawing of your system, including all of the part numbers
needed to order the system.

Die/Mold Clamps
Four models of Die/Mold Clamps are available. Part
number 62801 provides 18 kN of output pressure. It is only
available in the T-Slot mounting style. The T-Slot mount
allows the clamp to be mounted on a machine base via a
T-Slot nut, thus allowing the clamp to slide to and from
the workpiece. Part number 62802 provides 45 kN of
clamping force. It employs standard mounting bolts for
permanent mounting to the machine base, subplate, or
fixture plate. Part number 62803 also provides 45 kN
of clamping force. This clamp is provided with a Sensor
Interlock which, when wired to a control panel, indicates
whether the clamp is locked or not. Sensor Interlocks are
available as an accessory for part numbers 62801 and
62802. Part number 62804 is similar to part number 62802,
except it has a greater clamping range. It does not have
mounting holes for the Sensor Interlock. Die/Mold Clamps are
available with Viton® seals for high temperature applications.
Ideal for:
• Injection molding machines
• Die casting machines
• Punch presses
• Machining centers

Die/Mold StayLock® Clamp Applications
The Die/Mold Clamp is mounted (either
permanently, or by using T-Slots) on
the injection molding machine platen.
The mold is mounted on subplates. By
standardizing on subplates with the
same height and width, several different
molds can be used on one injection
molding machine. The mold is lowered
into the machine, the Die/Mold Clamps
are activated, hydraulic connections are
removed, and the job is run. A Sensor
Interlock can be added to indicate to
the operator that the Die/Mold Clamp
is clamping. If molds are used that
have a clamping slot, either a StayLock
Retractable Clamp or a StayLock
Rocker Clamp can be used.
Die/Mold Clamps are mounted on the
Punch Press table either permanently or
by using T-Slots. The top and bottom dies
are slid into place, hydraulic connections
are removed and the job is run.
Punch Press
Injection Molding
Press
At changeover time, the hydraulic quick
disconnect fittings are reconnected, the
die is removed and replaced with the
next die, and the process is repeated.
In some applications on punch presses,
the Die/Mold Clamp may create a shut
height problem. If this is the case,
the StayLock Rocker Clamp is an
excellent substitute.
Sensor Interlock
The Sensor Interlock (62816) can be mounted on the Die/Mold
Clamp and is used to indicate that the clamping piston is engaged
or disengaged. Because of the minimal movement of the clamping
piston, some applications may require more than a visual method of
determining if the Die/Mold Clamp is in the clamping position. The
Sensor Interlock is a normally open, 110 volt, 6 amp switch. It is
supplied with a 1.8 m long wire and mounting hardware to mount in
the control panel of a machine. The switch contacts on the Sensor
Interlock will only close when the clamping piston is within the
clamping range of the Die/Mold Clamp. It is included with Part
Number 62803.

No. 4,511,127
No. 4,471,293
Compact design and dual mounting capability make the
Jergens StayLock Rocker Clamp versatile for many
applications. The Rocker Clamps come in two styles. Part
number 62841 is typically used with standard height subplates
upon which the die, mold, or fixture plate is mounted. Part
number 62842 has an adjustable spindle which adapts to
the height of the workpiece. Both styles of Rocker Clamps
have drilled and tapped holes on the bottom of the clamp for
mounting T-Slot nuts for use on slotted tables. This method of
mounting allows the operator to slide the clamp to and from
the workpiece for easier part loading and unloading. Bolt down
mounting holes are also provided. For mounting applications,
contact the Jergens Technical Sales Department.
Ideal for:
• Holding dies on punch presses
• Molds on injection molding machines
• Dies on die casting machines
• Use on hydraulic fixtures

Jergens StayLock Toe Clamps are designed for edge gripping of parts when
the clamp height must be kept at a minimum, such as in a milling operation.
They are available in Low Toe (62811) or High Toe (62812) styles.
Toe Clamps provide two directional clamping forces: one pushes the
workpiece against a positive stop, the other pushes it down against the table
or fixture. A brass or steel insert is available on the low toe style Toe Clamp.
The inserts must be ordered separately.
IMPORTANT: Jergens 62811 Toe Clamp is supplied without toe insert.

Swing Clamps (Metric)
Jergens StayLock Swing Clamps are designed to be used when
accessible loading and unloading of a workpiece is required. The
clamping arm rotates 80° away from the workpiece. The Swing
Clamp operates in any position and is sealed so it can be used
with coolant applications.
Important: When using the High Volume Air-Powered Hydraulic
Pumps (61761 and 61762), the Flow Limit Valve (shown below)
must be used to limit the flow of hydraulic oil going to the clamp
port of the Swing Clamp. This will extend the life of the clamp by
minimizing the clamp arm from slamming into the clamping position.

Pre-Fill Boosters
• Self Bleeding
• Easy View Reservoir
• 15:1, 30:1, and 54:1 Boost Ratios
These units offer many more advantages than conventional
boosters, while maintaining the same basic simplicity. The pre-fill
booster has two automatic cycles. The first cycle pre-fills the work
circuit using low pressure with a large reservoir to provide volume.
The second cycle then automatically provides high pressure, as
needed. These units also provide automatic bleeding of the work
circuit. This self-bleeding feature negates the need to “bleed the
lines” after it is set up.
The pre-fill booster is ideal for any general use production system
requiring maximum efficiency with minimum effort! Pre-fill boosters
must be used in the upright (vertical) position.

Air-Powered Hydraulic Pumps
Jergens Air-Powered Hydraulic Pumps are used as a power source to activate Hydraulic Clamps. Shop air is introduced
into the Filter/Regulator and converted to hydraulic pressure. These pumps are available in two styles: the High Volume
Pump (61761 and 61762) with Boost Ratios of 20:1 and 50:1 and the standard, more compact “shoebox” pump (61755 and
61756) with Boost Ratios of 36:1 and 71:1. The Air-Powered Hydraulic Pumps are easy to use, energy efficient, versatile
and affordable. They are completely self-contained and do not require any external reservoirs or motors.
NOTE: See page 66 for Valve and Subplate options.

Pump Performance
The maximum output pressure at no flow is somewhat above the nominal ratio times the air drive pressure. This relationship
will fall off due to the increased effect of the air drive return spring force (equivalent to approximately 6 psi /0.41 bar air drive
at top of stroke, 8 psi /0.55 bar at bottom of stroke). Data is based on standard muffler arrangement and on flooded suction.
63
www.jergensinc.com
Shoebox™ Pumps
The “Shoebox” Pump is a low cost, compact unit used on smaller
hydraulic circuits. Its small size offers the versatility of mounting
on wheels (such as a workcart) and moving the pump from
workstation to workstation. Like the High Volume Pump, this pump
allows independent control of multiple workstations.

Breadbox™ Pumps
High Volume Air-Powered Hydraulic Pump
The Jergens High Volume Air-Powered Hydraulic Pump converts standard
and accessible low pressure shop air to hydraulic pressure up to 5000
psi/345 bar. These pumps offer large reservoir capacities and allow
independent control of multiple work stations. They are designed to
provide high volume output throughout the pump’s entire pressure range.
Jergens Air-Powered Hydraulic Pumps are used as a power source to
activate StayLock Clamps. Shop air is introduced into the Filter/Regulator
and converted to hydraulic pressure. These pumps are available in two
styles: the High Volume Pump (61761 and 61762) with Boost Ratios of
20:1 and 50:1 and the standard, more compact “Shoebox” pump (61755

Valves and Subplates
for Air Powered Hydraulic Pumps
Zero-Leakage Valve
Part Number
61642
For inline applications, use the 61642 Valve mounted on a
61646 Subplate (Order Part Number 61643). This set-up is also
recommended for use with High Volume Air-Powered Hydraulic
Pumps (61761, 61762) in StayLock and standard applications. For
manifold mounting, directly on the pump, the 61647 Subplate and
61642 Valve are recommended. Because the Jergens Air-Powered
Hydraulic Pump provides only the necessary hydraulic pressure
to clamp and unclamp the StayLock Clamps, the Four-Way, ZeroLeakage Valve is recommended to prevent the unnecessary running
of the pump, thus minimizing pump maintenance and wear.

Installation Tips for Plumbing Hydraulic Systems
Hose
The use of hydraulic hose is only recommended when the
need for flexibility exists. Generally, the only hydraulic hose in
an application is that used to connect the power source to the
fixture.
All hydraulic hoses expand under pressure. This uses costly
energy as well as volume. Some hoses expand at a greater
rate than others, even though size remains the same.
Fittings
Pipe Thread Fittings
Upon installation, apply a good sealing compound on threads
of fitting only. When Teflon tape is used, overlap threads
1-1/2 to two turns tightly in direction of thread. Be careful not
to extend tape over end of fitting. Do not overtighten pipe
threads as they may put
unnecessary strain on pressure vessels.
Straight Thread Fittings (SAE J514)
Generally speaking, an 2.5 meters length of hydraulic hose
will expand at a rate absorbing 16.5 cm3 of high pressure
oil at
200 bar.
These fittings require no sealing material as the built-in
o-ring provides a positive seal. The threads are a Class 2
straight thread with no taper. Before installation, be sure to
lubricate the
o-ring. Tighten these fittings to approximately 70-210 N.m.
When applying hose, the following is recommended:
The Tube Flare
Do Not:
• Overextend bend radius of hose.
• Put unnecessary strain at fitting ends.
• Subject hose to abrasive conditions.
• Use hose that hasn’t been identified.
Cut tube squarely and remove any burrs. Split flares may
be caused by the tube being too hard, opening up of
scratches
and draw marks, or failure to deburr tube end.
Place nut, then sleeve onto tube with open end of nut and
toe end of sleeve toward end of tube.
Do:
• Use a minimum size of 3/8" (9.5mm)I.D.
• Check with factory for alternate brands.
• Use firesleeve protective covering in applications
where flame is present (like weld fixtures).
• Make sure power source has enough high pressure
volume to compensate for hose expansion.
Tubing
Whenever possible use 3/8" diameter steel fluid line tubing
for hydraulic lines. This is a low carbon, soft tube and readily
available. Depending on the application, two types are
recommended:
Flare to standard 37° angle (maximum diameter of flare
is equal to maximum diameter of sleeve). A correct flare
should extend beyond the inside diameter of toe on sleeve
but not beyond
outside diameter of toe on sleeve.
Never attempt to spring tube to force alignment using the
fitting installed. This can damage the flare and wrinkle,
kink or flatten the tube. This can be avoided by using the
correct tools.
• 3/8" diameter (9.525mm) x .049 (1.245mm) wall thickness
for pressures to 3000 p.s.i.(205 bar)
• 3/8" diameter (9.525mm)x .065 (1.651mm)wall thickness
for pressures to 5000 p.s.i.(345 bar)
When rigid tubing is applied to air circuitry, use copper tube.
This will reduce the corrosive effect of water most likely found
in your air lines. Caution: Do not use copper in a high pressure
hydraulic circuit!

Locating Components
Bullet Nose Pins are used for aligning
two pieces of a fixture together. The
round and relieved style are used in
conjunction with a matching bushing to
locate radially on the round pin.
The flats on the relieved pin prevents
binding, yet allows a high degree of
accuracy to be maintained.
Dowel Pins
Precision Expanding Dowels
Application: to join 2 workpieces
• Material: Steel, hardened to Rc 50-55
• Self-Centering and Repeatable to within
± 0.013 mm
• Top and bottom half of dowel expand
seperately

screw, insert the dowel into the
locating hole of the first part,
and expand the bottom half
with a hex wrench.
slide the locating hole of the
second part over the dowel
and expand top half with a hex
wrench.
Work Support Jacks
Sine Fixture Keys locate jigs and fixtures on
machine tool tables and position the part in one
operation. They eliminate the need to slot fixture
bases, make step fixture keys, or drill and tap
keys. Simply ream two holes.
The unique expansion shaft allows the key to
be locked in the fixture from either the top or the
bottom using a standard hex wrench.
Inspection Balls
Work Jacks provide consistent support
and rigidity to odd shaped work-pieces.
They are designed to prevent workpiece
deflection under forces created during
machining operations. Precision mated
locking jaws grip the jackpost from both
sides creating a vise-like action.
Used as reference points for inspection
applications in conjunction with Coordinate
Measuring Machines to accurately measure
the workpiece.
Spring Loaded Devices
Unlike conventional spring
plungers, the Jergens SOLID
DRIVE Plunger is one integral
piece of steel: hex drive, plunger,
and body. No set screw to
separate from plunger body, no
lost springs to retrieve, no need
for “easy-out” tools.
Best of all, when adjusting
SOLID DRIVE, you can be sure
the spring plunger
is turning and not just a set
screw.

Expanding MicroTM Clamps
The Jergens patented “Tru-Center” products are the only pad
type on the market to provide true center line clamping. The
cut-away drawing illustrates how this works. The center line of
the pad and the center line of the nut always intersect at the
point of contact between the pad and the workpiece.
CAM Clamp
Measured from the centerline, each
face of these low profile clamps
increases 1mm from the smallest
to the largest face.
Jergens Expanding Micro Clamps allow you to fixture more
parts on your fixture plates. The unique expanding design
can hold two parts at once when used with a positive stop.
Adjustable Micro Clamps decrease
design and set-up times for
modular fixtures, work cubes,
and standard fixtures. Without
changing hole locations, clamping
range from 12mm to 35mm can be
achieved. The clamps are available
with either smooth or serrated faces
which make them ideal for clamping
machined parts, castings, and
rough cut stock. The clamps work
with a cam action, always following
the contour of the workpiece for
maximum surface contact.
ID Expansion Clamp
The ID expansion clamp is the ideal way to hold parts
on an inside diameter for multiple machining on a
vertical or horizontal machining center. The customer
machines the mild steel clamp to match the bore of the
part ensuring proper fit. Often times the clamps can
be remachined for different size jobs.
Threaded Inserts
Thread Repairs & Reinforcements are Made Quickly
Jergens Keylocking Inserts are easy to use for:
• repairing and reinforcing threads
• Relocating holes that have been drilled or tapped in the wrong location
• Fill holes that are too large
