Safety Precautions (Shock Absorbers)
Handling Instructions and Precautions
The following is a safety precaution to Shock Absorbers. For
other safety precautions, be sure to read the precautions on
p.49.
Danger
●Do not touch or approach too close to the product while it is
in operation. Also, do not attempt to mount a shock absorber
or adjust operations while devices are operating. Unintended
movement of devices could result in personal injury.
General precautions
If mounting in locations subject to dripping water, dripping oil,
etc., or to large amounts of dust, use something to cover and
protect the unit. Accumulations of water, oil, or dust can reduce
the shock absorber’s service life.
Warning
●Never loosen or remove the small screw on the rear end
surface of the shock absorber. The oil inside will leak out and
damage shock absorber function, which could result in injury.
● For product mounting, always observe the handling
instructions and precautions. In addition, when a product has
been mounted, before starting operation always check
whether mounting nuts have been attached and are secured,
etc. Looseness in the mounting nuts could lead to equipment
damage, or to accidents.
Caution
● Do not coat the sliding sections with any lubricant
whatsoever. Such lubrication could alter or degrade the
properties of the product materials, or reduce performance.
●Attempting to use the shock absorber with cap over the
specification range could result in damage to the cap or to its
flying off and causing personal injury. Moreover, if cracks or
fractures appear in the cap, replace it as quickly as possible.
Attention
●When the product’s service life is completed or when it is no
longer needed, dispose of it as an industrial waste product,
in accordance with the Waste Disposal and Public Cleaning
Law, or with other local laws and ordinances. Note that
because the special oil used in the KSHC series (clean room
specification) gives off hydrofluoric acid, a corrosive, toxic
substance, when incinerated, disposal should be performed
at an incinerator equipped with acid-resisting toxic removal
facilities. If large volumes need disposal, consign the
operation to a registered waste disposal company.
●The maximum absorption performance in the specifications
are values at normal temperatures (20〜25°C [68〜77°F]).
Be aware that performance and characteristics may change
depending on the operating temperature.
● The shock absorber’s absorption capacity can change
depending on the impact speed. Use it within the range
shown in the selection graphs (impact mass and impact
speed graphs) on p.572, 580, 586 and 593.
Adjustment of shock absorption capacity
● Adjustable absorption capacity type : KSHE and KSH series
1. Align the white mark on the shock absorption adjusting knob
to 2 or 3 on the scale.
2. For cases where the stroke end is still undergoing shocks,
turn the adjusting knob toward 6 on the scale. In cases
where the rod stops before the preset stroke end, or when
the shock at time of impact is very large, turn the adjusting
knob toward “0” on the scale.
3. When adjustment is complete, always be sure to tighten the
lock screw to secure the adjusting knob in place.
4. The KSHE series are designed so that the final orifice hole is
closed at the stroke end. Shortening the stroke could lead to
an inability to adequately absorb the impact energy. It is
recommended that use of the full stroke be made.
Moreover, the shock absorber for the KSHE series operate
differently when its rod is manually pushed in as opposed to
actual operation.
● Fixed absorption capacity type : KSHJ, KSHA, KSHC series
For the fixed absorption capacity type, shock absorption
capacity cannot be adjusted. See the Selection Guideline on
p.572, 580, 586 to select a model with the optimum shock
absorption capacity.
Mounting
1. Mount the shock absorber so that the load contacts at the
center of the rod, and it is not subjected to off-centered
loads. An off-centered load could result in breakage or
defective rod returns. If there is concern that off-centered
loads will occur, install a guide, etc.
2. Two or more shock absorbers can be mounted in parallel, to
boost absorption capacity. In such an arrangement, however,
be careful to ensure that the load is evenly distributed to
each shock absorber.
3. The surface in direct contact with the shock absorber rod
should have a hardness of HRc40 or more (excluding with
cap models).
4. When mounting the shock absorber, do not exceed the
maximum tightening torque for the hexagon nut, shown in the
table below. Excessive tightening could damage the unit.

●Fixed absorption capacity type
KSHJ, KSHA, KSHC series
1. If using “with cap” or changing the stroke to adjust absorption
capacity, use a stopper.
2. If using “with cap”, always mount a stopper nut (-S) or an
external stopper to ensure that the cap is not subjected to
loads at the stroke end. For the stopper nut mounting
position, see the dimensions in the table below.
While the shock absorber can be used without a stopper nut
(-S) or external stopper, in such an arrangement, the stop
position may change due to deformation of the cap after a
long period of use.

●Adjustable absorption capacity type
KSHE and KSH series
1. Do not use the end surface of the shock absorber body in the
rod side as a stopper. Always use a stopper nut (Order code:
-S) or external stopper.
2. When using the stopper nut, adjust the stopper nut location
so that it protrudes 0.5 mm [0.02 in.] from the end surface of
the KSHE series shock absorber body, and 0.5 to 1.0 mm
[0.02 to 0.04 in.] from the KSH series.
3. When using an external stopper, mount so that impacting
objects are stopped 0.5 mm [0.02 in.] in front of the end
surface of the KSHE series shock absorber body, and 0.5 to
1.0 mm [0.02 to 0.04 in.] in front of the KSH series.
4. For swing impacts, ensure that the angle of eccentricity
between the load direction and the center line of the shock
absorber is 3° or less.
KSHES series
1. For holders that can directly stop loads, use a stopper type
holder (-HS). If using holders that do not have a stopper
function (-H), use an external stopper.
2. Holders and external stoppers should receive all the
remaining energy for loads when stopping. Do not let the cap
become subjected to loads at the stroke end.
●Calculation
For the calculations, use the speed immediately before striking the absorber. For air cylinders, the speed immediately before striking is
larger than the average speed obtained from the “time required for cylinder stroke”. In this case, shorter strokes increase the speed,
and it reaches 1.2 to 2.0 times higher than the average speed.

Evaluation of Cleanliness (Shock Absorber KSHC Series)
There is currently no standard in JIS or elsewhere for
methods of evaluating shock absorber’s cleanliness.
Koganei has therefore independently established our
in-house measurement methods, to conduct the
cleanliness evaluations.
●Measurement method
1. Measure particles in the clean bench (Figure 1)
without activating the measurement use shock
absorber and load driving cylinder in the clean
bench (to measure the background valve).Note
Note : Under the background measurement condition,
the number of particles measures zero.
●Outline of particle measuring device

Class 3Note2
equivalent
Shock absorber
for measurement
Load
Cylinder for
driving load
2. Drive the load and activate the shock absorber
under the measurement condition, to measure
the particles.
M
Cover
●Measurement conditions
Load impact speed
: 300 mm/s
[11.8 in./sec.]
Shock absorber operating frequency : 30 cycle/minNote 1
Particle measurement time
: 1 minute
Suction rate
: 1 cf/min
Measured particles
: 0.1μm and larger
For reference, a graph of actual values is shown in
Figure 2.
The number of particles is the average value of the
test samples. Also, the smaller the angle variation of
eccentricity when mounting the shock absorber, the
lower the number of particles is likely to be. Mount
the shock absorber so that its angle of eccentricity to
the workpiece is as small as possible.
Notes: 1. The number of particles is based on 30 operation
cycles. The customer’s evaluation should be based
on the customer’s own operation frequency.
Notes: 2. Corresponds to FED-STD Class1.
Notes: 3. The number of particles in the graph are actual values measured under Koganei standards, and are not
intended to be guaranteed values.

Mounting Position for Holders and Sensor Switches
Moving Sensor Switch
When the sensor switch is mounted in the position in the diagram
(the figures in the tables are reference values), the magnet comes to
the maximum sensing position of the sensor switch at the end of
stroke .
●Loosening the sensor switch set-screw allows the sensor switch to
be moved along the axis direction of the shock absorber.
●Do not exceed a tightening torque of the set-screw 19.6N･cm
[1.73in･lbf].

Note: Mount the sensor switch so that it does not protrude from the holder.
Cautions: 1. The sensitivity of the sensor switch can vary depending on the
environment. If operation appears unstable, relocate the
sensor switch to an optimum location, and use a set-screw to
secure it in place.
Cautions: 2. Mount so that the sensor switch’s order code is displayed on
top.
