Precautions 

Be sure to read before handling. 

Refer to p.0-39 to 0-46 for Safety Instructions 

and common precautions. 

Precautions on handling 

Warning 

q Do not operate the cushion valve in the fully closed or fully 

opened state. 

� Using it in the fully closed state will cause the cushion seal to 

be damaged. Using it in the fully opened state will cause the 

piston rod assembly or the cover to be damaged. 

w Operate within the specified cylinder speed. 

� Failure to do so will damage the cylinder and the seals. 

Caution 

q Do not use the air cylinder as an air-hydro cylinder. This 

will cause an oil leak. 

w Install without twisting the bellows. 

� If the cylinder is installed with its bellows twisted, it could 

damage the bellows. 

Disassembly/Replacement 

Caution 

q Do not replace the bushings or the cushion seals. 

� The bushings and the cushion seals are press-fit. To replace 

them, they must be replaced together with the cover assembly. 

w To replace a seal, apply grease to the new seal before 

installing it. 

� If the cylinder is put into operation without applying grease to 

the seal, it could cause the seal to wear significantly, leading to 

premature air leakage. 

e Do not replace One-touch fittings. 

� Because pipe fittings are press-fit, they must be replaced 

together with the cover assembly. 

r Those with a bore of ø50 or more cannot be disassembled. 

� When disassembling a cylinder with a bore of ø20 to ø 40, use 

a vise or the like to hold the wrench flats portion of the tube 

cover or the rod cover on one side, while placing a wrench or 

an adjustable wrench on the other side to loosen and remove 

the cover. To replace, tighten it an additional 2… from the 

installed position. (Those with a bore of ø50 or more cannot be 

disassembled because they have been tightened with greater 

torque. If they must be disassembled, contact SMC.

A low hydraulic pressure cylinder used at a pressure of 1.0MPa or below. 

Through the concurrent use of a CC series air-hydro unit, it is possible to 

operate at a constant or low speed or to effect an intermediate stop, just 

like a hydraulic unit, while using pneumatic equipment such as a valve.

High speed operation/Long life 

Piston speed is between 50 and 500mm/s 

and long life is expected. 

Can operate without lubrication. 

The same installation dimensions 

as the standard cylinder. 

Auto switches can also be 

mounted. 

It can be installed with auto switches to simplify 

the detection of the stroke position of the cylinder.

The CG1R Series direct mount cylinder 

can be installed directly through the use 

of a square rod cover. 

Space saving configuration 

Because it is directly mounted without 

using brackets, its overall length is shorter, 

and its installation pitch can be made 

smaller. Thus, the space that is required for 

installation has been dramatically reduced.

Clean Series 

10-CG1RN 

Clean series (with relief port) 

The rod portion of the actuator has a double seal construction, and a relief 

port is provided to discharge the exhaust air directly outside of the clean room. 

Thus, it can be used in a Class 100 clean room.

The CG1R Series direct mount 

cylinder can be installed directly 

through the use of a square rod 

cover. 

Space saving configuration 

Because it is directly mounted without 

using brackets, its overall length is shorter, 

and its installation pitch can be made 

smaller. Thus, the space that is required for 

installation has been dramatically reduced.

Handling 

q Avoid using the air cylinder in such a way that rotational torque would be applied 

to the piston rod. 

� If rotational torque is applied, the non-rotating guide will become deformed, thus affecting the 

non-rotating accuracy. Refer to the table below for the allowable range of rotational torque. 

ø40/ø50/ø63 

0.44 

� To screw a bracket or a nut onto the piston rod, make sure to retract the piston rod entirely, and 

place a wrench over the flat portion of the rod that protrudes. To tighten, take precautions to 

prevent the tightening torque from being applied to the non-rotating guide. 

w To replace a rod seal, contact SMC. 

A rod seal could lead to an air leak, depending on the position in which it is fitted. 

Therefore, make sure to contact SMC if a rod seal must be replaced.

Designed with a low sliding resistance of the 

piston, this air cylinder is ideal for applications 

such as contact pressure control, which 

requires smooth movements at low pressures. 

Low sliding resistance 

Stable sliding resistance 

The sliding resistance remains stable even 

when the operating pressure changes. 

Long strokes can be manufactured. 

Auto switches can be mounted.

Precautions 




Refer to p.1.7-6 for precautions 

on series CG1. 

Handling 

Warning 

q In the direction of low friction operation, 

speed control must be effected through 

the meter-in system. 

With meter-out control, the exhaust pressure 

will increase and create a greater sliding 

resistance. 


Auto switches can be mounted. Mounting 

position/height is the same as the double 

acting/single rod style. Refer to p.1.7-12 and 1.7- 

13.1. 


Refer to p.1.7-45 for other mounting brackets. 


Refer to p.1.7-45 for part number of the switch 

mounting band for adding auto switches on 

built-in magnet cylinders.

Note 1) Other intermediate strokes can be manufactured upon receipt of order. Refer to p.1.7-46 for dimensions. 

Note 2) The longer the stroke, the greater the sliding resistance could become, due to the sagging of the piston rod. 

Therefore, consider installing a guide for such operation.

Selecting the Low Friction Direction 

q To use the air cylinder as a balancer, 

pressurize it only from one of the ports as 

shown in the application example, and 

keep the other port open to the 

atmosphere. 

To operate by applying pressure from 

the rod cover port: Low friction direction 

B type 

To operate by applying pressure from the 

head cover port: Low friction direction F 

type 

In either case, if the piston rod is moved 

by an external force, it will effect low 

friction operation both in the extending 

and retracting directions. 

w When it is necessary to operate it as an 

ordinary double acting cylinder at an even 

lower operating speeds, use a low speed 

cylinder (see "Made to Order" on Page
