Formula
Push Force = Bore Area x Pressure; Pull Force = (Bore Area - Rod Area) x Pressure; Volume = Area x Stroke / 231
Frequently Asked Questions
How is hydraulic cylinder force calculated?
Force equals pressure multiplied by piston area. For push (extend) force, use the full bore area. For pull (retract) force, subtract the rod area from the bore area to get the annular area.
Why is the retract force less than the extend force?
During retraction, hydraulic fluid acts on the annular area (bore area minus rod area), which is smaller than the full bore area used during extension. This results in less force but faster retraction speed.
