Allowable load mass
The allowable load mass changes by the arm opening angle.
Be sure to use the product within the allowable values in the graphs
shown below.
*The load indicates the total weight of the clamp arm, extension arm, and clamp-
ing block.
*When the operating time is 1 second.
Calculation procedure of allowable load mass
1. Calculate the distance Lfrom the fulcrum to the load center of gravity.
2. Check the arm opening angle of the product.
3. Read the allowable load mass from the graph.

Setup Procedure
Precaution
1) The tightening torque of the clamp arm is ø50: 12 to 15 N·m, and ø63:
15 to 20 N·m. Refer to pages 5 and 6 for details on the clamp arm.
2) This product is designed to be used after being externally adjusted
using a shim, and there is a mechanical difference of 0 to +0.5°at the
clamping end as shown in Figure 1.
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 a lateral load, such as galling, etc., is not
applied to the clamp arm.
A) Place the workpiece, supply air to the clamp side port without attaching the block on the arm side, and move 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 the space is 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 by the arm length and the operating pressure. Refer to the graphs on page 11.
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 in the clamped state, and confirm that the clamp arm does not open.

Setup Procedure CKZ3T-X2734
<Ex. 2 When using a hard stop: When not equipped with a workpiece receptacle>
A) Supply air at clamping port without installation of upper hard stop, and operate the clamp arm to the end of clamp.
B) In the state of A), attach the upper hard stop and adjust the shim qso that the space between the upper hard stop and the hard
stop is about 0 mm.
During this step, theoretically, there is no clamping force applied to the hard stop.
C) In order to generate clamping force from the state described in step B, insert an additional shim.
The thickness of the shim changes by the distance to the hard stop and the operating pressure. Refer to the graphs on page 11,
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 in the clamped state, and confirm that the clamp arm does not open.

Relation between shim thickness and clamping force
*Use this figure as a guide, as there is a tolerance of about 10% in the clamp cylinder body.
*When a shim exceeding the clamping force peak position on the graph is inserted, the lock will not be activated when clamped.
Insert a shim with appropriate thickness.
*Arm length “L” indicates the distance between the clamp arm shaft and the clamping position.
For distance “A” between knock positioning pinhole and clamp arm shaft, refer to Table 1.

1. Manual lock release
Be sure to confirm safety before manually releasing the lock,
and perform the work while the air is exhausted. The clamp
arm may operate.
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.

Specific Product Precautions
Be sure to read this before handling the products. For safety instructions and actuator
precautions, refer to the “Handling Precautions for SMC Products” and the “Operation
Manual” on the SMC website: http://www.smcworld.com
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 the replaceable parts, as the
performance may deteriorate.
3. Precautions for 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°. 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.
