14) When a cylinder is used in a clamping, sus pending, or lifting mechanism
There is a danger of workpieces dropping if there is a decrease of thrust due to a drop in circuit pressure
caused by a power outage, etc. Therefore, safety equipment should be in stalled to prevent damage to
machinery and/or human injury.
15) Do not use the product as a shock absorber.
If abnormal pressure or an air leakage occurs, the rotary actuator's speed reduction capability could become
severely affected, which could pose a hazard to humans or damage the machinery and equipment.
16) Do not stop or hold the product at midpoint by keep ing air pressure in the product.
For a product lacking an external stopping mechanism, if the directional control valve is closed to keep the air
pressure in the product in an attempt to stop the product at midpoint, it might not be possible to maintain that
stopped position due to an air leakage. As a result, it could pose a hazard to humans or cause damage to
machinery and equipment.
1) Use the product within the limits of the maximum usable stroke.
The piston rod will be damaged if operated beyond the maximum stroke.
2) Operate the cylinder component parts within a range such that collision damage will not
occur at the stroke end.
For applications where a piston with inertial force strikes a cover and stops at the stroke end, follow the
cylinder model selection procedure, or select while taking into account the allowable kinetic energy indicated in
each model's specifications.
3) Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low
speed to the desired speed setting.
4) If pressure is applied to the external cylinder parts, there is a possibility that air will get
inside the cylinder from the rod seal section. (Example: inside a chamber, etc.)
5) Do not use the product as a stopper.
Also when water, cutting oil, etc., directly splashes on a cylinder, please contact SMC for details.

9. Installations/Adjustment

1) Installing a protective cover (In the case of rear plate)
During mounting, handling and operation, the rear plate makes reciprocating movements.
Therefore, pay careful attention not to insert your hand, etc., between the cylinder and the rear plate.
When you are going to fit this product to the outside of your equipment, take preventative measures such as
installing a protective cover.
