Design/selection
1. Speci
fi
cation Con
fi
rmation
WARNING
■
Use the product within the speci fi cations range.
The products described in this catalog are designed to be used solely in compressed air systems. Do not use the products beyond the speci fi ed range of working pressure or ambient temperature, or it can lead to damage or abnormal operation. ( Refer to Speci fi cations ) .
When using working fluids other than compressed air and low-pressure oil, please consult with CKD.
2. Safety Design
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.
■
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.
■
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.
CAUTION
■
Please operate the product within the speci fi ed 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.

■
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.
Residual pressure relief valve
Pressure switch
■
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 antipopout feature.
3. Design by Purpose
WARNING
■
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.
■
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.
4. Usage Environment
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 fl uid 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 fl uid.
■
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.
5. Durability
WARNING
■
The durability may vary depending on the working conditions and product variation characteristics.
6. Air Supply
WARNING
■
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.
CAUTION
■
Please use dry compressed air that will not cause condensation within the piping.
Drying machine Air fi lter
( Mesh size < 5 μ m )
●
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.
■
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 af fi xed 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 af fi xed on it.
Please mount air fi lters with mesh size of 5 μ m or smaller.
● Please perform regular maintenance checks to air compressors.
7. How to Use
CAUTION
■
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 selfl u b r i c a t i n g m e t h o d o r p e r f o r m m a n u a l 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.
12
13
■
Please use a swing cylinder ( with rod eye ) that can rotate by some degree when the load ’ 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 fi t: 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.
8. Ensure Space
CAUTION
■
Please ensure that there is sufficient space around the cylinder for mounting, disassembly, wiring and piping work.
9. Precautions in the User Manual
CAUTION
■
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.

1. Mounting
WARNING
■
When mounting the cylinder, please take protective measures to prevent the load from dropping or tipping over.
CAUTION
■
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.
2. Air Supply
CAUTION
■
Prior to the use of pneumatic element circuit, please mount the air fi lter.
● Please mount the air drying machine and fi lter 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.
Drying machine Air fi lter
( Mesh size < 5 μ m )
● 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.
3. Piping
CAUTION
■
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.
Solid and liquid sealant
Solid and liquid sealant
■
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 fireretardant or metal pipes.
■
Please use galvanized pipes, stainless steel pipes, nylon pipes, rubber pipes or other pipes made of anti-corrosion piping materials.
■
When supplying the compressed air after piping connection, do not apply high supply pressure abruptly.
● If the piping joint comes loose or the piping fl ies off, it will lead to accidents.
14
■
