Hydraulic Cylinder Bore Size Calculator – Calculate Required Bore Diameter

Hydraulic Cylinder Bore Size Calculator

Calculate the theoretical minimum piston bore required to achieve a target hydraulic cylinder force at a known working pressure. Supports push (extend) and pull (retract) calculations in Metric and Imperial units.

Conceptual cross-section. D is the cylinder bore diameter measured across the piston; d is the piston rod diameter. The pull sketch shows one continuous rod, without an extra rod segment.

Hydraulic Cylinder Force Calculator – Push & Pull Force

Hydraulic Cylinder Force Calculator

Calculate, verify and understand push & pull force.

A hydraulic cylinder converts hydraulic pressure into linear force. The force depends on the pressure available at the cylinder port and the effective piston area. For a single-rod cylinder, push force and pull force are different because the piston rod occupies part of the piston area on the rod side.

1. What Is Hydraulic Cylinder Force?

Hydraulic cylinder force is the theoretical linear force generated when hydraulic pressure acts on an effective piston area. For a single-rod hydraulic cylinder, the effective area changes depending on whether the cylinder is extending or retracting.
