Theoretical Push and Pull Forces
The cylinder output forces are derived from the formula:
F = P x A
10000
Where F = Force in kN.
P = Pressure at the cylinder in bar.
A = Effective area of cylinder piston in
square mm.
To determine the bore size for the application take the
following steps.

Cylinder Weights and Force
1. Select the Operating Pressure column closest to that
desired.
2. In the same column, identify the force required to
move the load (always rounding up). If the piston rod is
in compression use the ‘Push’ row and if the piston rod
is in tension use the ‘Pull’ row.
3. In the row to the left is the bore required.
If the cylinder envelope dimensions are too large for
the application, increase the operating pressure to the
maximum pressure in the table below, if possible, and
repeat steps 1 - 3.
Cylinder Weights
To determine the weight of a Series CHE cylinder,
first select the proper basic zero stroke weight for the
mounting required, and then calculate the weight of the

cylinder stroke and add the result to the basic weight.
For extra rod extension, use piston rod weights per
mm in Table C.
Table B Double Rod End CHE Cylinder Weights in kg.
Table C Piston rod weights in kg.
