Calculation
example
Bore size: 63, Arm length: 200 mm,
Operating pressure: 0.5 MPa
With an arm length of 200 mm and an operating pressure of 0.5 MPa,
according to the graph, the maximum clamping force is 2000 N.
The allowable load mass changes depending on the arm opening angle.
Be sure to use the product within the allowable values shown in the graph below.
∗
The load indicates the total weight of the clamp arm and clamping block.

Calculation procedure for allowable load mass
q
Calculate the distance
L from the fulcrum to the load center of gravity.
w
Check the arm opening angle of the product.
e
Read the allowable load mass from the graph.
