Unknown Cylinder

If you are designing a hydraulic machine that requires a hydraulic cylinder but do not know what size to make it then the Cylinder bore can be calculated here, required thrust and Working Pressure must be known.

Useful conversions factors:

1kW = 1.34hp

1bar = 14.5psi

1cm3 = 0.061 cu.inch

1cm2 = 0.155 in2

1Litre = 0.22 UK Gallons = 0.26 US Gallon

1kg = 2.2 lbs

Total thrust force (Fst) Kg
