Formula
Force (lbs) = 4,000 PSI × π × (Bore ÷ 2)²
At 4,000 PSI, a cylinder’s push force depends entirely on the bore diameter. Larger bores produce dramatically more force — doubling the bore quadruples the force.
Common Applications at 4,000 PSI
- Heavy duty: Large presses, construction equipment, steel mills
