Procedure
Precautions
1) The tightening torque of the clamp arm is 6.0 to 9.0 N·m for ø40. Refer
to page 32 for details on the clamp arm.
2) There is a mechanical difference of 0 to +0.5°at the clamping end as
shown in Figure 1. Be sure to make adjustments externally using a
shim. Refer to page 36.
3) Be sure to use a speed controller, and make adjustments according to
the following conditions.
Unclamping to clamping: 1 second or more
Clamping to unclamping: 1 second or more
If excessive kinetic energy is applied, there is a possibility of damage.
4) When using a side guide:
Attach the side guide so that lateral loads, such as galling, etc., are not
applied to the clamp arm.
A) Place the workpiece, supply air to the clamping port without attaching the block on the arm side, and operate the clamp arm to
the end of the clamp.
B) In the state of A), attach the workpiece and the arm side block, and adjust the shim so that there is a space of about 0 mm.
During this step, theoretically, there is no clamping force pressing down on the workpiece.
C) In order to generate a clamping force from the state described in step B), insert an additional shim.
The thickness of the shim changes depending on the arm length and the operating pressure. Refer to page 36.
Please note that the graph should only be used as a guide as there is a tolerance of about 10% in the clamp cylinder body.
D) Exhaust the air while in the clamped state, and confirm that the clamp arm does not open.

<Ex. 2 When using a hard stop: When not equipped with a workpiece receptacle>
A) Supply air to the clamping port without installing the upper hard stop, and operate the clamp arm to the end of the clamp.
B) In the state of A),attach the upper hard stop and adjust shim qso that there is a space of about 0 mm between the upper hard
stop and the hard stop.
During this step, theoretically, there is no clamping force applied to the hard stop.
C) In order to generate a clamping force from the state described in step B), insert an additional shim.
The thickness of the shim changes depending on the distance to the hard stop and the operating pressure. Refer to page 36,
and consider the distance to the hard stop as the arm length.
Please note that the graph should only be used as a guide as there is a tolerance of about 10% in the clamp cylinder body.
D) In the state of C), adjust shim wso that the arm side block contacts the workpiece.
E) Exhaust the air while in the clamped state, and confirm that the clamp arm does not open.

Procedure for changing the arm opening angle
1) When changing the arm opening angle, be sure to confirm
that the air inside the cylinder has been exhausted.
2) Remove the switch cassette.
*8 types of arm opening angles (unclamping angles) 30°,
45°, 60°, 75°, 90°, 105°, 120°, and 135°are available for
each standard size.
3) Remove the dog of the A part, and mount a different dog for
other angles using the tightening torque below. (Confirm the
direction of the angle display.) Then mount the switch
cassette using the tightening torque below.
4) Remove the stopper bolt of the head cover, and mount a
different stopper bolt for other angles using the tightening
torque below. (Confirm the angle display.)

1) Mount the top cover to the clamp cylinder, then tighten it to
the specified tightening torque below.
*It is not possible to change between cover materials afterward
(rubber cover type/metal cover type).
*Refer to Replacement Parts (page 29) for the part numbers of the
top cover replacement parts.
Caution Be sure to confirm safety, and perform the work while the air is exhausted.

CKZT Series

1. Manual lock release
Be sure to confirm safety before manually releasing the lock,
and only perform work while the air is exhausted. Otherwise,
the clamp arm may operate unexpectedly.
¡ In the case of a rubber cover, the lock can be released easily
by hitting the round tab on the cover with a plastic hammer.
¡ In the case of a metal cover, the lock can be released easily
by opening the cover and hitting the tab of the knuckle joint
with a plastic hammer.
¡Provide enough space to perform a manual lock release.
Caution Caution
2. Do not disassemble the power clamp cylinder.
The power clamp cylinder consists of a completely sealed
structure in order to protect it from welding spatter. Do not
disassemble, except for when replacing any of the replaceable
parts, as this may cause the performance to deteriorate.
3. Vertical clamping
When mounting the clamp arm in a vertical clamping position,
mount as shown in the figure below. The maximum arm
opening angle is 105°for offset 15 and 120°for offset 45
(mounting hole symbol B). In the case of a metal cover type,
select a 45 mm offset for the clamp arm. When a 15 mm offset
is selected, the metal cover and clamp arm will interfere and
the lock cannot be released manually.
4. Proximity switch output
The switch output signal is output near the clamping end and
the unclamping end respectively. The switch output signal on
the clamping side does not output the status where the power
clamp cylinder is locked by the toggle mechanism.
5. With manually operated handle
Operating force of the handle should be 150 N or less. Exces-
sive forces applied to the handle will lead to breakage or de-
formation.
6. Operating time and allowable load mass
Fast operation (short stroke times) or excessive loads will lead
to the breakage or deformation of the product. It is recom-
mended to install shock absorbers to reduce impact force in
these instances.
