3.Precautions 3-1.Caution on Design Warning ① There is a possibility of dangerous sudden action by air cylinders if sliding parts of machinery are twisted due to external forces, etc. In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur.
Page 7
Caution ① Do not wipe off the grease attached on the sliding face of the cylinder. If the grease is removed from the sliding part of the cylinder forcibly, a malfunction could occur. When the cylinder has been in operation for a long distance, the sliding parts become discolored black.. In such cases, to prolong cylinder life, wipe off the grease from the sliding parts, and add new grease.
3-2.Selection Speed control When cylinder is adjusted to desired speed, install speed controller such as SMC’s AS series near supply port of air. For this adjustment, either of supply air or exhaust air is squeezed, generally exhaust air is done. Direction control When actuatig direction of cylinder is changed, install adequate solenoid valve selected among SMC’s various models.
3-3.Mounting Caution ① Be certain to match the rod shaft center with the load and direction of movement when connecting. When not properly matched, problems may arise with the rod and body, and damage may be caused due to friction on areas such as the inner body surface, bushings, rod surface, and seals. ②...

⑩ When a load, cap, single knuckle joint or double knuckle joint is mounted on the end of the rod, do not exceed the max. tightening torque in the following table. Bore size Thread size Max.tightening torque(N・m) Φ4 M2×0.4 Φ6 M3×0.5 Φ10 M4×0.7...
3-4.Piping Caution ① Before piping Before piping, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. ② Wrapping of pipe tape When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not get inside the piping.
3-6.Air Supply For compressed air supplied to the cylinder, use the air which is filtrated by SMC’s filter such as AF series and adjust to specified setting pressure by SMC’s regulator such as AR series. Warning ① Use clean air. Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction.
3-8.Maintenance Warning ① Perform maintenance procedures as shown in the instruction manual. If they are handled improperly, malfunction or damage of machinery or equipment may occur. ② Removal of equipment, and supply/exhaust of compressed air Before any machinery or equipment is removed, first ensure that the appropriate measures are in place to prevent the falling or erratic movement of driven objects and equipment, then cut off the electric power and reduce the pressure in the system to zero.
3-10.Snap ring installation/removal Caution ① To replace seals or grease the cylinder during maintenance, use an appropriate pair of pliers (tool for installing a type C snap ring for hole). After re-installing the cylinder, make sure that the snap ring is placed securely in the groove before supplying air.
3-11.Auto switches The type and specifications of applicable auto switch and the cautions for handling them can be found in the catalogue and operation manual respectively. ① Proper Auto Switch Mounting Position (Detection at stroke end) and Its Mounting Height ≒H * When a screw is not mounted on the end of the rod, a nut cannot be mounted.

4.Model selection 4-1.Allowable Kinetic Energy Caution When driving an inertial load, operate a cylinder with kinetic energy within the allowable value. The range in the chart below that is delineated by bold solid lines indicates the relation between load weights and maximum driving speeds. Bore size Φ4 Φ6...
4-2.Lateral Load at Rod End Caution In principle, the load applied to the piston rod should always be kept in the axial direction. If this situation cannot be avoided, keep the lateral load applied on the bushing of the cylinder, to 1/50 or less of the maximum output of the cylinder.
5.Pneumatic circuit The typical circuit for CJP2 series where air filter, regulator, solenoid valve and speed controller (meter-out) are used for operation is as follows. Pressure gauge Speed Pressure controller Regulator source Air filter Drain catch Mist separator Air tank...
