9 types of arm opening angles (unclamping angles) 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120° and 135° are available for each standard size.
Arm opening angle change procedure
1) When changing the arm opening angle, be sure to operate the cylinder to the clamping end, and confirm that the air inside the
cylinder has been exhausted.
2) Loosen the switch cassette mounting screw, and remove the switch cassette.
3) Remove the hexagon socket head cap screw (part A), and change the position of the screw to the required angle position, and
tighten it to the tightening torque shown below.
4) Mount the switch cassette to the body, and tighten the switch cassette mounting bolt to the tightening torque shown below.
When mounting the clamping arm in a vertical clamping position, note that the maximum angle will change.
5) Remove the stopper bolt of the head cover, and mount a different stopper bolt for other angles using the tightening torque below.
When replacing the stopper bolt, fix the head cover securely. If the stopper bolt is replaced without fixing the head cover, the
head cover may be displaced, causing air leakage. (Confirm the direction of the angle display.)
For the applicable stopper bolt part numbers, refer to page 4 for CKZ3N, and page 15 for CKZ3T.
