Specific Product Precautions

Be sure to read this before handling the products.

Refer to back page 50 for Safety Instructions and pages 3 to 12 for Actuator and

Auto Switch Precautions.

Mounting

Caution

1. Make sure that the surface on which the cylinder is

to be mounted is flat (reference value for flatness:

0.05 or less).

Dual rod cylinders can be mounted from 3 directions,

however, make sure that the surface on which the cylinder is

to be mounted is flat (reference value for flatness: 0.05 or

less). Otherwise, the accuracy of the piston rod operation is

not achieved, and malfunctioning can occur.

2. Piston rod must be retracted when mounting the

cylinder.

Scratches or gouges in the piston rod may lead to damaged

bearings and seals and cause malfunctions or air leakage.

Caution

1. After adjusting the stroke, make sure to tighten the

hexagon nut to prevent it from loosening.

Dual rod cylinders have a bolt to adjust 0 to –5 mm strokes on

the retracted end (IN).

Loosen the hexagon nut to adjust the stroke; however, make

sure to tighten the hexagon nut after making an adjustment.

Never operate a cylinder with its bumper bolt removed.

Also, do not attempt to tighten the bumper bolt

without using a nut.

If the bumper bolt is removed, the piston hits the head cover

causing damage to the cylinder. Therefore, do not use a

cylinder without a bumper bolt.

Furthermore, if the bumper bolt is tightened without a nut, the

piston seal is caught in the leveled part, damaging the seal.

Stroke Adjustment

A bumper at the end of the bumper bolt is replaceable.

In case a missing bumper, or a bumper has a permanent

settling, use following part numbers for ordering.

Disassembly and Maintenance

1. Never use a cylinder with its plate removed.

When removing the hexagon socket head cap screw on the

end plate, the piston rod must be secured to prevent from

rotating. However, if the sliding parts of the piston rod are

scratched and gouged, a malfunction may occur. If the plate is

not required for your application, use the cylinder that does not

come with a plate, available through made-to-order (-X593) on

page 759.

2. When disassembling and reassembling the cylinder,

please contact SMC or refer to the separate operation

manual.

Do not operate the cylinder in a pressurized environment.

The pressurized air may flow inside the cylinder due to its

construction.

Do not use as a stopper. This may cause malfunction.

When using as a stopper, select a stopper cylinder

(RS series) or a compact guide cylinder (MGP series).

1. A sudden extension may occur with CXS6.

CXS6 has a low internal volume and sudden extension/erratic

movement may occur particularly when it is used at low speed.

This sudden extension can be mitigated by combining the use

of meter-in and meter-out speed controllers.

Warning

1. Take precautions when your hands are near the

plate and housing.

Take sufficient care to avoid getting your hands or fingers

caught when the cylinder is operated.

Caution

1. Plug the appropriate supply port(s) according to the

operating conditions.

Dual-rod cylinders have 2 supply ports for each operating

direction (3 supply ports for ø6 only). Plug the appropriate

supply port according to the operating conditions. When

changing the port position, use the removed plug or a new

plug. If reusing the removed plug, apply sealant, etc., before

reassembly. If using a new M5 plug, apply a thin layer of

grease all the way around the male thread before use. In

addition, clear any foreign matter adhered to the port the plug

was removed from before piping.

After reassembly, be sure to check for air leakage before

operating the product.

When operating an actuator with a small diameter

and a short stroke at a high frequency, the dew

condensation (water droplet) may occur inside the

piping depending on the conditions.

Simply connecting the moisture control tube to the

actuator will prevent dew condensation from oc-

curring. For details, refer to the IDK series in the

Best Pneumatics No. 6.

Precautions

Be sure to read this before handling

the products.

Refer to back page 50 for Safety

Instructions and pages 3 to 12 for

Actuator and Auto Switch Precautions.

Selection

Caution

Operate the cylinder until the stroke end.

If the stroke is restricted by the external

stopper and clamp workpiece, effective

cushioning and noise reduction will not be

achieved.

2. Adjust the cushion needles to absorb

the kinetic energy during the cushion

stroke so that excessive kinitic energy

does not remain when the piston reach-

es the stroke end.

If the piston reaches the stroke end with ex-

cessive kinetic energy remaining (more

than the values given in table (1) below)

due to an improper adjustment, excessive

impact will occur, causing damage to ma-

chinery.

Rotations

3 rotations or less

2.5 rotations or less

Use a 3 mm flat head watchmakers screw-

driver to adjust the cushion needles to the

fully closed position, as this will cause dam-

age to the seals. The adjusting range for the

cushion needles must be between the fully

closed position and the open position rang-

es indicated in the table above. A retaining

mechanism prevents the cushion needles

from slipping out; however, they may spring

out during operation if they are rotated be-

yond the ranges shown above.

Precautions for selection standard, mount-

ing, piping, and operating environment are

same as for the standard series.
