LOAD - PRESSURE CORRELATION CHART
Models BRK4T & BRK10T
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:

*For Model BRK4T, A = 0.998 in²; For Model BRK10T, A = 2.411 in²
Example 1
Example 2
where F = Force/ Load (lbs)
P = Hydraulic Working Pressure (psi) and
A = Ram Effective Area (in²)*
Pressure (psi) of 4 Ton
(lbs)
Ram, where A = 0.998 in
Model BRK4T exerting 5,000 lbs of force will require what pressure?
Pressure = Force / Ram Effective Area = 5,000 lbs / 0.998 in² = 5,010 psi
Model BRK10T operating at 6,000 psi will generate what force?
Force = Pressure x Ram Effective Area = 6,000 psi x 2.411 in
F = P x A
Ram, where A = 2.411 in
