4. To screw a bracket onto the threaded portion at the tip of 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.
5. To remove and install the retaining ring for the knuckle pin or the
clevis pin, use an appropriate pair of pliers (tool for installing a type
C retaining ring). In particular, use a pair of ultra-mini pliers for
removing and installing the retaining ring on the ø10 cylinder.
6. In the case of auto switch rail mounting style, do not remove the
rail that is mounted. Because retaining screws extend into the
cylinder, this could lead to an air leak.

Copper and Fluorine-free Air Cylinder
(For CRT manufacturing process)
Construction (Not able to disassemble)
Eliminates the effects by copper based ions and fluorine
based resins, etc. over the color cathode ray tube.
Making copper based materials into electroless nickel
plated treatment or changing them to the non-copper
materials in order to prevent copper ions from generating.

Caution on Handling
Be sure to read before handling.
Refer to front matters 54 and 55 for Safety Instructions and
pages 3 to 11 for Actuator and Auto Switch Precautions.

Series CJ2K
Caution
1. During installation, secure the rod cover and tighten by applying an
appropriate tightening force to the retaining but or to the rod cover
body.
If the head cover is secured or the head cover is tightened, the
cover could rotate, leading to the deviation.
2. Tighten the retaining screws to an appropriate tightening torque
within the range given below.
ø10: 10.8 to 11.8 N·m, ø16: 20 to 21 N·m
3. In the case of a non-rotating cylinder, do not operate it 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.
