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.

Calculation
example
Bore size: 63, Arm opening angle: 90°,
Distance to the center of gravity: 250 mm
With an arm opening angle of 90° and a 250 mm dis-
tance to the center of gravity, according to the graph,
the maximum allowable load mass becomes 4.0 kg.

Procedure
CKZ3T-X2734
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.
