LOAD - PRESSURE CORRELATION CHART
Models 50040 & 50100
Always monitor the force applied to work piece by using a load cell and indicator or you may monitor pressure
developed in the ram by using an in-line pressure gauge, then calculate the applied force using the formula:
F = P x A
where
F
= Force/ Load (lbs)
P
= Hydraulic Working Pressure (psi) and
A
= Ram Effective Area (in²)*
Load
(lbs)
Pressure (psi) of 4 Ton
Ram, where A = 0.998 in
2
Pressure (psi) of 10 Ton
Ram, where A = 2.411 in

*For Model 50040,
A
= 0.998 in²; For Model 50100,
A
= 2.411 in²
Example 1
Model 50040 exerting 5,000 lbs of force will require what pressure?
Pressure = Force
Ram Effective Area
=
5,000 lbs
0.998 in² = 5,010 psi
Example 2
Model 50100 operating at 6,000 psi will generate what force?
Force = Pressure
x
Ram Effective Area =
6,000 psi x 2.411 in
2
= 14,466 lbs
