systems, machines, and equipment.
When designing and manufacturing equipment using CKD products, the manufacturer is obligated to ensure that
the safety of the mechanism, pneumatic control circuit and/or water control circuit and the system that runs the
electrical controls are secured. It is important to select, use, handle, and maintain CKD products appropriately to
ensure their safe usage. Observe warnings and precautions, etc. to ensure device safety. Check that device safety
is ensured, and manufacture a safe device.
Use the product within the specifications range.
This product must be used within its stated specifications. In addition, never modify or additionally machine this product.
This product is intended for use in general industrial machinery equipment or parts. It is not intended for use outdoors or
for use under the following conditions or environments.
(Note that this product can be used when CKD is consulted prior to its usage and the customer consents to the CKD
product specifications. The customer should provide safety measures to avoid danger in the event of problems.)
●Use for applications requiring safety, including nuclear energy, railways, aircraft, marine vessels, vehicles, medical
devices, devices or applications in contact with beverages or foodstuffs, amusement devices, emergency cutoff circuits,
press machines, brake circuits, or safety devices or applications.

WARNING
■Use the product within the specifications range.
The products described in this catalog are designed to be
used solely in compressed air systems. Do not use the
products beyond the specified range of working pressure or
ambient temperature, or it can lead to damage or abnormal
operation. (Refer to Specifications).
When using working fluids other than compressed air and
low-pressure oil, please consult with CKD.
WARNING
■If the cylinder working force changes due to
torsion of machine's sliding part, there is a risk
that the piston rod may pop out.
This may cause personal injuries such as hands or feet
pinching or damages to machinery. Therefore, the machine
shall be designed to be adjustable to ensure its smooth
operation and avoid human body injuries.
■If there is a risk of endangering your personal
safety, please mount the protection guard.
If the cylinder actuator may endanger your personal safety,
please mount the protection guard. Please adopt a structure
that prevents access to cylinder actuation area or direct
contact with human body.
■Please take into account the voltage sag
condition due to power failure.
When the cylinder is used as a clamping unit, the clamping
force will be reduced if there is a voltage sag caused by
power failure or other reasons, thus making the work piece
come loose and drop. Please install a safety device that will
not cause personal injuries or damages to the unit. The
hoisting device and lifter should have anti-drop design as well.
■Please take into account the possibility of
power source failures.
Please optimize the design of devices that utilize pneumatic,
hydraulic and electric power control, so that physical injuries
or machinery damages will be avoided in case of power
source failure.
■
Please use an anti-pop out design for the circuit.
When the cylinder is actuated through a directional control
valve with central venting or start-up operation is performed
after circuit residue pressure is relieved, the actuated object
will pop out at high speed if the single side of piston is
pressurized in case of cylinder air evacuation. This may
cause personal injuries such as hands or feet pinching or
damages to machinery. Therefore, design a circuit with anti-
popout feature.
■Please take into account the operation status
during emergency stop.
Please adopt a reasonable design, so that the safety device
can be actuated to stop the machine in case of system
abnormalities (such as emergency stop and power failure)
and personal injuries or system and equipment damages
due to cylinder operations can be avoided.
■Please take into account the operation status
when the cylinder is restarted after emergency
stop or abnormal stop.
Please adopt a reasonable design to prevent personal
injuries or equipment damages due to restart operation.
If the cylinder needs to be restored to start position, please
design a control device that ensures safety.
■Please take necessary precautions to avoid
negative impacts on humans and properties
caused by product failures.

CAUTION
■Please operate the product within the specified
working range, so that the piston will not be
damaged due to collision when reaching the
stroke end.
If the piston collides with the cylinder lid at the stroke end
and stops due to the inertia effect, please operate the
product within the allowable absorbed energy.
■
Please mount a speed regulation valve on the cylinder.
Please operate within the working piston speed of each cylinder.
■Please mount a "pressure switch" and "residual
pressure relief valve" on the compressed air
supply side of the unit.
●The pressure switch should be set so that the product will
not operate until the set pressure is reached. The
residual pressure
relief valve will evacuate residual compressed air from the
pneumatic circuit, thus preventing accidents caused by
pneumatic element movement due to residual pressure.

When a deceleration circuit or buffer device is required
If the actuated object moves at a high speed or is relatively
heavy, the cylinder cannot absorb shocks effectively alone.
Therefore, please design a circuit that decelerate the
actuated object timely, or use an external buffer device to
reduce shocks. In this case, please fully consider the rigidity
of mechanical units.

WARNING
■Never mount the product in locations where it
may be exposed to rain, water splash, direct
sunlight and high humidity.
■Never use the product in environments where it
is prone to corrosion.
Otherwise it may result in product damages or abnormal operations.
In addition, even if some cylinder components (such as
piston rod and pull rod)would undergo electroplating
process, their manufactured parts (thread face along its
width, cutting face)are not electroplated. Therefore, the
cylinder may rust under normal conditions. Please take
preventive measures when necessary.
■
If the product is to be mounted in locations where
it may be exposed to heavy dust and splashes of
water or oil, cutting fluid and coolant, please use
devices such as protection guard.
In dusty locations, please use products equipped with
powerful scraper. Under liquid splashing environments,
please use products that provide excellent resistance
against cutting fluid.
■
When the ambient temperature drops below 5℃,
the remaining moisture within the circuit may
freeze, thus resulting in abnormal operations or
other failures. Therefore, please remove residual
moisture to prevent the circuit from freezing.
■The product has been initially lubricated and
operates well under a self-lubricating condition.
Use turbine oil ISO VG32 (without additives)if
necessary for lubrication . If the lubrication
operation is interrupted, lack of initial lubricant
volume will cause abnormal operation. Be sure
to lubricate the product continuously.
You need to decide whether to adopt self-
lubricating method or perform manual
lubrication for the pneumatic device, and
implement strict management on the selected
lubricating method.
■Avoid simultaneous operation of multiple
cylinders if possible.
Otherwise, the piston rod may be twisted when the
simultaneous operation fails, thus leading to abnormal
operations. If simultaneous operation of multiple cylinders is
required, please mount an additional guiding device with
high rigidity.
■Before mounting the rod eye, please check that
the cylinder can freely rotate without any
intervention across the whole stroke length.
■
Ultra-dry air supply is not intended for standard
pneumatic elements. Please only use pneumatic
elements designed for such air supply.
●Ultra-dry compressed air will shorten the service life of
pneumatic elements.
●Please use DC type solenoid valves.
■
Please use compressed air that is free of oxidized
air compressor oil, tar and carbon black.
●Oxidized oil, tar or carbon may come into and get affixed
on the interiors of pneumatic elements, add resistance to
the sliding part and lead to abnormal operation.
●Oxidized oil, tar or carbon may be blended with the
lubricant and cause the sliding part of pneumatic
elements to wear down.
■Please use compressed air that is free of solid
foreign matters.
●If the solid foreign matters come into pneumatic elements,
they may wear down the sliding part and get affixed on it.
Please mount air filters with mesh size of 5μm or smaller.
●Please perform regular maintenance checks to air
compressors.
CAUTION
●Temperature drop within air compressor piping and
pneumatic elements may create condensate.
●If the piping volume is larger than the cylinder volume
(converted under atmospheric pressure), the compressed
air within the cylinder will not be completely evacuated
each time the solenoid performs switchover, and dew will
be formed and accumulated within the cylinder, thus
generating condensate.
●The condensate may come into the air flow path within
the pneumatic elements and lead to instantaneous
congestion, thus causing abnormal operations.
●The condensate may cuase rusts and eventually lead to
pneumatic element failures.
●The condensate may be blended with the lubricant and
eventually lead to poor lubrication.
4. Usage Environment
WARNING
WARNING
■
The durability may vary depending on the working
conditions and product variation characteristics.
■
Please use clean and dry air to create compressed air.
The compressed air must be free of synthetic oil (including
chemicals and organic solvents), salt and corrosive gas, or it
may lead to product damages or abnormal operations.
■Please use dry compressed air that will not
cause condensation within the piping.

7. How to Use
■When inertia force or vibration is generated
If the cylinder is mounted on a moving component (such as
X-axis module and pallet), the moving component will
generate inertia force or vibration when stopped. Please
consider these factors during design.
■About middle-position stop
When using a 3-position directional control valve (center
closed type)to perform middle-position stop of cylinder
piston, precise stop under low oil pressure cannot be
achieved due to air compressibility reasons. In addition,
since the valve or cylinder cannot ensure complete air
tightness, the piston may not be kept in the stop position for
a long time. If you require that the piston be kept in the stop
position for a long time, please consult with CKD.

13
■Please use a swing cylinder (with rod eye)that
can rotate by some degree when the load’s
movement direction changes with the cylinder
operation. Also, mount the cylinder so that the
rod-end connecting piece is in parallel with the
movement direction of cylinder body.
■Do not use a fixed type cylinder with a
mechanical arm that makes circular motion. In
this case, please use a swing cylinder.
■To prevent piston rod-end thread damage, shaft
sleeve wear and burning, etc., please use a
universal joint or simple universal joint to
connect piston rod end and load. This will also
prevent torsion at any position across the
stroke length.
■If the clearance between the rod eye and
corresponding bearing is too large, a bending
force will be exerted on pins or shafts.
Therefore, excessive clearance must be
avoided.
(Recommended fit: H10/e8)
■A tiny amount of oil may leak from the sliding
part, sealing elements and gaskets of the
cylinder. In locations that should be oil-free,
please use the cylinder with caution.
■Please ensure that there is sufficient space
around the cylinder for mounting, disassembly,
wiring and piping work.
■Please specify maintenance conditions of the
unit in the User Manual.
●Under certain usage conditions or operating environments
and by using certain maintenance approaches,
noteworthy degradation of product functionality may
occur and
product safety cannot be ensured. Proper maintenance
will maximize the product functionality.
■The cylinder switch may malfunction if there is
a magnetic substance such as a metal plate
installed adjacently. Please maintain a distance
of at least 10mm from the cylinder surface.
(Same for all bore sizes)
■The cylinder switch may malfunction if installed
adjacently to another cylinder. Please maintain
a safe distance shown as follows from the
cylinder surface.
(Same for all bore sizes)

WARNING
■When mounting the cylinder, please take
protective measures to prevent the load from
dropping or tipping over.
■Prior to piping work, do not remove the packing
bag from the cylinder or the dust-proof seal
from the pipe end.
●Otherwise, foreign matters may come into the cylinder
through the pipe end and lead to failures or malfunctions.
■If the cylinder mass exceeds 15kg, please use a
lifting sling.
■Do not place any object on the cylinder body
and sliding part of the piston rod, and collision
with other objects should be avoided to prevent
damages and dents.
The bore size tolerance is rather tight. Therefore, even slight
deformation could cause abnormal operations.
In addition, damages or dents on the sliding part of the
piston rod may cause damages to sealing elements, thus
leading to air leakage.
■If the load movement direction is not in parallel
with the piston rod axis, the piston rod and
cylinder body may be twisted, causing the
piston rod to pop out. This may even cause
burns and damages to the piston rod. Make
sure that the piston rod axis is in parallel with
the load movement direction.
■Please take measures to prevent burns to the
rotating parts.
Grease the rotating parts (such as pins)to prevent burns.
■Prior to the use of pneumatic element circuit,
please mount the air filter.
●Please mount the air drying machine and filter to remove
moisture from the piping. In addition, mount the filter
near the directional control valve (on the primary side)to
remove rusts, foreign matters and condensate.
■
When supplying the compressed air after piping
connection, do not apply high supply pressure abruptly.
●If the piping joint comes loose or the piping flies off, it will
lead to accidents.
●If the compressed air is supplied too slowly, sealing
pressure may probably not be generated due to effect of
internal sealing mechanism of solenoid valve, thus
leading to air leakage.
●The cylinder may operate drastically.
■Please refer to the User Manual during piping
work and never connect the wrong port.
●Otherwise, it may lead to malfunctions.
■How to wind the sealing tape during piping
connection: wind the sealing tape clockwise,
starting from an inside position more than 2
threads away from the front end of piping
threaded portion.
●If the sealing tape extends beyond the front end of piping
threaded portion, screw-in operation will cause the
sealing tape to break off and tape residues will be left
inside to cause failures.
■Try to prevent the piping connected to the
cylinder from falling off due to vibration,
loosening and tensile load.
●If the piping on the exhaust side of the pneumatic circuit
falls off, the cylinder speed will be out of control.
●In case of using jaw clamping mechanism, the jaw may
be opened and this will lead to dangers.
■When using nylon or polyurethane pipes,
please pay attention to the following items.
●In areas where spatters are present, please use fire-
retardant or metal pipes.
■Please use galvanized pipes, stainless steel
pipes, nylon pipes, rubber pipes or other pipes
made of anti-corrosion piping materials.

using the product. Keep the manual properly for future
reference.
■When using a speed regulation valve to adjust
the speed, open the needle valve gradually from
its closed state to make adjustments.
If the adjustment is made directly when the
valve is open, there is risk that the piston rod
would pop out.
■Cushion level of cylinders with air cushion has
been factory-adjusted. Please use the cushion
needle valve to make readjustment depending
on the load and piston speed.
Open the needle valve gradually from its closed state to
adjust cushion level. If the needle valve gets too loose, the
cushion effect will no longer exist and the needle valve may
fall off.
After the adjustment, tighten the nut (Hexagon nut)on the
needle valve.
Please use the valve within the allowable kinetic energy
range.
Otherwise it may result in product damages.
■When actuating the cylinder, never reach into or
put your hands in its actuation range.
