Series CHE Compact Hydraulic Cylinders

Theoretical Push and Pull Forces
The cylinder output forces are derived from the formula:
F= PxA/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.
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.
