Precautions

Usage Precautions

Warning

*Do not apply reverse torque to the piston rods sticking out from both sides of this cylinder at the same time. Torque makes connection threads inside loosen, which may cause an accident or malfunction.
In addition, install or remove the load with the 2 flats of the piston rod fixed on the load mounting side. At this time, be careful not to apply torque to the non-rotating guide. Do not fix the other side of the 2 flats of the piston rod and then apply reverse torque.

Example of correct usage of cylinder

Example of incorrect use of cylinder

Caution

• *1Avoid applying rotational torque to the piston rod. The non-rotating guide may become deformed, compromising the accuracy. See below for the rotational torque allowance.
• *2The load on the piston rod must always be in an axial direction.

• ø12 (12‑mm bore size): 0.04 N·m or less
• ø16 (16‑mm bore size): 0.04 N·m or less
• ø20 (20‑mm bore size): 0.2 N·m or less
• ø25 (25‑mm bore size): 0.25 N·m or less

Installation and Removal of Retaining Rings

Caution

• *1For installation and removal, use an appropriate pair of pliers (tool for installing a type C-type retaining ring).
• *2Even when using an appropriate pair of pliers (tool for installing a type C retaining ring), proceed with caution as there is a danger of the retaining ring flying off the end of the pliers (tool) and causing bodily injury or damage to nearby equipment. After installation, make sure that the retaining ring is securely seated into the retaining ring groove before supplying air.

*See the manufacturer’s catalog for product information other than that detailed above.
