Load - Pressure Correlation For Model J50040 & J50100

Always monitor the force applied to workpiece by using a load cell and indicator or you may monitor pressure developed
in the ram by using an inline pressure gauge, then calculate the applied force using the formula:

F = P x A

For model J50040,

A = 0.998 in² ;

For model J50100,

A = 2.411 in²

Example1

Model J50040 lifting 5,000 lbs will require what pressure?

Pressure = 5,000 lbs / 0.998 in² = 5,010 psi

where F = Force/ Load (lbs);

P = Hydraulic working pressure (psi) and;

A = Ram effective area (in²)

Example2

Model J50100 operating at 6,000 psi will generate what force?

Force = 6,000 psi x 2.411 in

2

= 14,466 lbs
