Ram calculator

Enter your system pressure and flow, choose a bore, rod and stroke, and see how the cylinder will perform.

System input

Available pressure (bar)

Max pressure 210 bar, 3000 psi.

Available flow (LPM)

Required input power·kW

Input power makes no allowance for inefficiency.

Bore (inches)

Select a combination from the configurator. Other combinations are available on request.

Rod (inches)

Stroke (mm)

Based on maximum lengths in the configurator. Others are available on request.

Extend force·kN

Kilonewtons to metric tonne force, multiply by 0.10197.

Retract force·kN

Extend volume·L

Retract volume·L

Extension time·s

Extend speed·m/s

Max extension speed 0.5 m/s.

Retract time·s

Retract speed·m/s

Max extension speed 0.5 m/s.

Ram extension (%)

If in doubt of forces along the extension axis, use 100 percent extension as the worst case example.

Buckling factor, tube rear mount·

Important note: calculations are based on indicative cylinder loading and on fixed end conditions. Always seek advice if in any doubt.

Side load

Hydraulic rams are not designed for side load.

Environmental conditions

Hydraulic rams should be designed with the environment in mind when it comes to special materials and paint.

Safety

Safety should always be considered when supporting loads, and correct valving should be used.

If you are unsure on anything, seek expert advice.
