ADJUSTA BLE CUSHION
S T ROKE A DJUSTORS
C USHIONS
Cushions are designed to provide smooth deceleration,
external energy absorption and noise reduction, over
the last 15º of rotation. Cushions trap air at the end
of stroke by blocking or restricting the discharge port.
The trapped air is diverted through a small needle
valve which generates a back pressure on the discharge
side of the piston. This back pressure resists the forces
exerted on the internal parts of the rotary actuator,
thus causing a slowing of the external mass.
Stroke adjustors are screw-type adjustable stops at
end of rotation. They should be used when the
exact final position of rotation is best determined on
the assembled machinery or when final position
requ irements may vary with different machine set ups.
C AUTION : Cushion needles should be set between one
half and one full turn from seated position.
Setting should result in continuous speed
reduction throughout the cushion length.
Needle adjustment is set too far closed when
there is an abrupt change in speed as the
actuator enters the cushion. Never operate
with needle in seated position or unscrewed
beyond the point where the seal relief in the
thread is visible.
C AUTION : Cushion needle adjustment is a crucial factor
in achieving optimum cushion performance.
If the needle valve setting is too far open
cushion capacity will be reduced or rendered
ineffective; if set too far closed, cushion action
will generate shock and pressure spikes in
excess of actuator rating.
N OTE : Cushions and stroke adjustors are not available
on the same cylinder end cap for standard
models. Consult factory for special
design considerations.

INTERNA L STROKE ADJUSTOR
AND ADJUSTA BLE CUSHION
S T ROKE A DJUSTORS
S T ROKE A DJUSTORS & A DJUSTABLE C USHION
Adjustable cushion and stroke adjustors are combined
as a single end of stroke option.
The Ohio Oscillator design moves the cushion
engagement position along with the end of stroke
adjustment so the full engagement length of the
cushion is retained at any stroke adjustment setting.
ADJUSTA BLE CUSHION
C USHIONS
C AUTION : Cushion needles should be set between one
Cushions are designed to protect the actuator from
damaging impact at the end of rotation. When
properly sized and adjusted, cushions may also
provide smooth deceleration, external energy
absorption and noise reduction.
Cushions trap flu id at the end of stroke by blocking
or restricting the discharge port. The trapped flu id is
diverted through a small needle valve which generates
a back pressure on the discharge side of the piston.
The back pressure resists the forces exerted on the
rack by the propelling action of the actuator and the
slowing of external mass which imparts engery into
the actuator through the shaft. A check valve is
included to bypass the cushion action at the start of
rotation in the reverse direction.
half and one full turn from seated position.
beyond the point where the seal relief in the
thread is visible.
N OTE : Cushions needle adjustment is a crucial factor
in achieving optimum cushion performance.
If the needle valve setting is too far open,
cushion capacity will be reduced, or rendered
ineffective; if set too tight, cushion action will
generate shock and pressure spikes in excess
of actuator rating.

END CAP OPTIONS
External stroke adjustors permit 0-30º of adjustment at
the end of rotation. The adjustor stop, which contains
the port, is set in position with a wrench on external
flats and locked in place with a jam nut against a
thread seal.
MODELS 900 TO 7500
H Y D R AU L I C
E XTERNAL S T ROKE A DJUSTORS
I N TERNAL S T ROKE A DJUSTOR &
A DJUSTABLE C USHION
The 0-5º internal stroke adjustor and the adjustable
cushion are combined into a single option. This design
permits the full cushioning effect at any stroke
adjustment setting.
MODELS 15000 AND UP
Cushions are designed to provide smooth deceleration,
external energy absorption and noise reduction, over
the last 15º of rotation. Cushions trap flu id at the end
of stroke by locking or restricting the discharge port.
The trapped flu id is diverted through a small needle
valve which generates a back pressure on the discharge
side of the piston. This back pressure resists the forces
exerted on the internal parts of the rotary actuator,
thus causing a slowing of the external mass.
C AUTION : Cushion needles should be set between one half
and one full turn from seated position. Setting
should result in continuous speed reduction
throughout the cushion length. Needle adjustment
is set too far closed when there is an abrupt
change in speed as the actuator enters the
cushion. Never operate with needle in seated
position or unscrewed beyond the point where
the seal relief in the thread is visible.
C AUTION : Cushion needle adjustment is a crucial factor in
achieving optimum cushion performance. If
the needle valve setting is too far open, cushion
capacity will be reduced, or rendered ineffective;
if set too far closed, cushion action will generate
shock and pressure spikes in excess of
actuator rating.
*N OTE : When ordering a double rack model with stroke
adjustors it is necessary to order end of stroke
adjustors for both cylinders. When only one stroke
adjustor is used for end of stroke adjustment on a
double rack model the maximum operating pressure
must be limited to 103.4 bar.
ADJUSTA BLE CUSHION
I N TERNAL S T ROKE A DJUSTORS
Internal stroke adjustors permit 0-5º of adjustment. A
threaded bushing within the end cap is set in position
by a hex wrench inserted through the port and locked
in place with a set screw.

*N OTE : Cushions and external stroke adjustors are not
available on the same cylinder end cap for
standard models. Consult factory for special
design considerations.

E XTERNAL A DJUSTOR & F IXED C USHION
A combined fixed orifice cushion and stroke adjustor is
available on Ohio Oscillator hydraulic actuators. Like
the air units, setting the stroke adjustment does not
affect cushion engagement length. However, the
amount of cushion effect is not adjustable in this option.

EXCEPT FIXED
ORIFICE DELETED
The fixed cushion orifice is sized to absorb the propelling
torque developed on the working side of the actuator at
speeds of less than 90º/sec and may not be sufficient to
adequately stop additional inertial loads imparted
through the shaft.
A ir bleeds not available with this option.
EXTERNA L STROKE
ADJUSTOR & FIXED CUSHION
C USHIONS
TYPICA L MODELS H67 -H2002
EXCEPT FIXED ORIFICE DELETED
Cushions trap flu id at the end of stroke by blocking
or restricting the discharge port. The trapped flu id is
diverted through a small needle valve which generates
a back pressure on the discharge side of the piston.
OHIO
This back pressure resists the forces exerted on the
rack by the propelling action of the actuator and the
slowing of external mass which imparts energy into
the actuator through the shaft. A check valve is
included to bypass the cushion action at the start of
rotation in the reverse direction.
DOUBLE RACK ADJUSTOR & CUSHION COMBINATIONS
ADJUSTA BLE CUSHION
External stroke adjustors, (0- 20º) and adjustable
cushions are not available on single rack hydraulic
units. Double rack units can be specified with
external stroke adjustors on one rack (or end) and
adjustable cushions on the other rack (or end.)
The 0-5º internal stroke
adjustor and the adjustable
cushion are combined into
a single option. The Ohio
Oscillator design moves
the cushion engagement
position with end of stroke
adjustment so the full
engagement length of
the cushion is retained at
any stroke adjustment
setting. Not available
on standard H6/H12
models-Consult factory.
When independent adjustable cushions and external
stroke adjustors are used, stroke reduction has a direct
effect on cushion engagement. The cushion arc will
be reduced by the amount of stroke reduction
adjusted into the actuator.
*N OTE :
When ordering a double rack model with stroke
adjustors it is necessary to order end of stroke adjustors
for both cylinders. When only one stroke adjustor is
used for end of stroke adjustment on a double rack
model the maximum operating pressure must be
limited to 69 bar.

*CAUTION: Stroke Adjustors and Cushions should never be adjusted while the system is under pressure.

ENGINEERING
APPLICATION EX A MPLES, ROTA RY MOTION
The torque requ ired to put a load into motion by a
rotary actuator is the sum of the static torque, the
dynamic torque and the gravitational torque. Static
torque is the torque of friction, dynamic torque is the
torque requ ired to accelerate to desired speed and
gravitational torque is the torque necessary to lift a
weight against gravity. It is suggested that an actuator
with reserve capacity of at least 20 percent be selected
to accommodate variations within the system.
R OTATION I N V ERTICAL P LANE
The maximum torque requ ired to rotate the weight (W)
thru an angle Ø in a vertical plane will occur when the
arm is horizontal. This torque is determined by the
equation: T = Wr. If the arm mass is significant its effect
on the torque requ ired must be calculated.
As the arm approaches vertical
the requ ired torque becomes
less because the arm length (r)
becomes shorter as a function
of the sine of the angle.
The torque requ ired at any
position can be determined by:
H ORIZON TAL R OTATION
OF
T = Wr sin Ø
S UPPORTED W EIGHT
Bearing
N OTE : (W) should include the weight of the turntable as
well as the load. Torque (Tf) requ ired to overcome
friction must be added to the acceleration torque
(Ta) prior to selecting the proper rotary actuator
model. The friction torque can be subtracted from
the deceleration torque if desired.
U NSUPPORTED W EIGHT
The torque (Ta) requ ired to accelerate (rotate)
unsupported weight in a
horizontal plane can
be determined by:
Angular acceleration (α) is usually uniform and can be
determined by:
Where ω= (θ 2 - θ 1)
(t2 -t1)

Jω 2

Jω 2
2θ d
Since deceleration energy must equal acceleration
energy (Tdθ d=Taθ a) and actuator pressure is
proportional to torque, we can set up a simple
example of angular travel and pressure.
E XAMPLE : If a load is uniformly accelerated thru
100º rotation at 69 bar, you can determine the
deceleration pressure to stop the load in 80º by
the following:
100º x 69=Pressure to decelerate=86 bar
80º
A NOTHER E XAMPLE : Uniformly accelerate a load thru 165º
rotation at 34.5 bar, then stop the motion within the
last 15º of rotation:
165º x 34.5 bar=Pressure to decelerate=379 bar
15º
Accel.@ 34.5 bar

@ 379 bar
Deceleration pressure of 379 bar to dissipate the

prove to be destructive to the system.

@ 138 bar
C AUTION : See Caution note on Page 31.
D ECELERATION
Deceleration torque is often the least understood and
in many cases the most important requ irement to
be considered.
The time requ ired to decelerate the load within a given
angle of rotation should usually be longer than the time
requ ired to accelerate the same load to a requ ired speed.
54
Ek
Another example illustrates the use of flow control
valves to control output flow. A mass accelerated
through 40º at 138 bar, then moving at constant speed
for 125º, will generate a destructive deceleration pressure
of 368 bar to dissipate the kinetic energy within the last
15º of rotation.
Ta = J O<
Where J = Wr2
g
α = (ω 2 - ω 1)
(t2 -t1)
Consider that acceleration energy equals torque times
the angle of acceleration (Taθ a). In terms of kinetic
energy it is:
Td
Tf = W Cf rb
OF
Since energy in must equal the energy out, if the rotary
actuator is used to decelerate the load, any reduction in
deceleration time will result in increased back pressure
which may be damaging to the rotary actuator and
other system components. In all circu its this back
pressure must be absorbed into the existing system.
The deceleration torque requ ired to stop the
load is kinetic energy divided by the angle
of deceleration:
The previous example does not include any
considerations for friction. Friction Torque (Tf) can
be determined by the product of the weight (W),
the coefficient of friction (Cf) and the bearing
radius (rb).
H ORIZON TAL R OTATION
This is important because energy bu ilt up during
uniform acceleration must be absorbed during
deceleration by a bu ild up of back pressure in the
actuator cylinder.
M O O G
Decel.
@ 368 bar
In addition, since it is difficult and in many cases
impractical to remove system pressure during
deceleration, one must consider the torque developed
by the system pressure while driving the load through
the deceleration distance (rotation) in addition to the
kinetic energy already existing.
The optional MOOG FLO-TORK bu ilt-in cushions are
designed to help decelerate the load during the last 15º
of rotation. The deceleration pressure should not exceed
the rated pressure of the rotary actuator model selected.

results when an unbalanced torque acts on

A NGULAR R OTATION is the arc traveled in rotary

C AUTION : Cushion needle adjustment is a crucial factor in
achieving optimum cushion performance. If
the needle valve setting is too far open, cushion
capacity will be reduced or rendered ineffective;
if set too far closed, cushion action will
generate shock and pressure spikes in excess of
actuator rating.

CUSHION CAPACITY AND SIZING
Cushions are the simplest design alternative, but
consideration must be given to the cushion energy
absorption capacity. Exceeding rated cushion capacity
can reduce actuator life or result in severe actuator
damage. To determine if a cushion is su itable for the
application, calculate the total energy that must be
absorbed and compare with the cushion capacity rating.

C AUTION :
Et = 99.7 + 68.9 + 0 Nm = 168.6 Joules
Total energy to be absorbed in the example is
168.6 Joules. The cushion capacity of Model 3700 when
properly adjusted is 188.7 Joules. This is adequate to
meet the deceleration requ irement.
l
M O O G
Cushion needle adjustment is a crucial factor in
achieving optimum cushion performance. If the
needle valve setting is too far open, cushion
capacity will be reduced or rendered ineffective;
if set too tight, cushion action will generate
shock and pressure spikes in excess of actuator rating.

ENGINEERING
High rotational velocity and/or large mass in rotary
motion can cause damaging impact at the end of
stroke. Deceleration and absorption of rotating system
energy can be achieved with cushions, external shock
absorbers or flu id circu it devices which reduce speed as
the actuator approaches the end of travel.

U SING H ARMONIC M OTION
The advantages of using rotary actuators, combined
with harmonic -motion-producing linkages, compared
to the straight line cylinders, are derived from the
principle of converting a constant speed rotating
motion to a sinusoidal (sine-wave) motion which
produces maximum linear force where needed for
acceleration . . . and just the opposite force for
deceleration and stopping the load. Meanwhile, you
develop maximum linear speed during the middle of
the 180º rotation cycle.
Deceleration is usually the big problem and the speed
of any reciprocating or oscillating motion is normally
limited by the ability to control deceleration.
Deceleration valves are expensive, difficult to field-adjust
and susceptible to tampering and to malfunction from
contaminated oil or air.
A simple flow control valve to maintain constant
speed of the rotary actuator can, when combined with
harmonic linkage, decelerate the load smoothly to rest.
Acceleration control is easy to achieve and usually
is limited only by the available hydraulic or
pneumatic power.
H IGH S PEED -S MOOTH S PEED C ON T ROL
G EN TLE A CCELERATION
Controlled acceleration and deceleration . . . with the
MOOG FLO-TORK rotary actuator rotating at a constant
speed. You can go faster and smoother using rotary
actuators than with any other method.
You have the maximum mechanical advantage where you
need it . . . at the beginning of the travel. Force arrow
shows maximum force in the direction of start-up to get
you started faster.
S PEED
G EN TLE D ECELERATION
Maximum velocity is when the load is halfway to its
destination. Smooth acceleration to that point . . . then
smooth deceleration.
You have the maximum mechanical advantage where
you need it . . . at the end of the travel. Deceleration is
a “mirror” reflection of acceleration and the load will be
slowed down by the rotary actuator automatically.

BEARING LOAD CAPACITIES - MOOG FLO-TORK
hydraulic rotary actuator bearings are sized to accept
external loads. This feature often allows the shaft
to be mounted directly to the rotary actuator without
flexible couplings and outboard bearings, utilizing
the MOOG FLO-TORK actuator as the bearing.

*C AUTION : L is the maximum allowable external radial load at
the maximum distance D (distance from housing
to middle of keyway as shown on the chart as
dimension D). To find L match the model and
maximum operating pressure to find the maximum
external radial load L on the rotary actuator. T is
the maximum allowable external thrust load. To
find T, match the model and maximum operating
pressure to find the maximum thrust load on the
rotary actuator. For combined radial and thrust
loads consult factory.
S PECIAL C ONSIDERATIONS
1. SPECIAL SYSTEM DESIGN consideration must be given to
applications that involve high speed rotation, high cycle life,
eccentric external loading conditions, or when the actuator
maximum allowable pressure is exceeded. These design
considerations may include internal or external shock
absorbers, external controlled stops, special material or
hardness treatment for actuator internal parts and special
hydraulic system controls.
B) Providing suction line filters of 100 mesh screen or finer
and pressure line filters of 25 micron nominal or finer.
7. SLOW ROTATION - The enclosed gear cases of MOOG
FLO-TORK hydraulic rotary actuators are filled sufficiently
with gear oil to lubricate the moving parts by immersion and
splashing. In applications with slow rotation caution must be
taken to insure that lubricant reaches upper gear components.
8. HOLLOW SHAFT - A high strength steel shaft with full length
key engagement is recommended to mate with MOOG
FLO-TORK’s high strength hollow shaft pinion.
