Bore Diameter

Definition

The inner diameter of a hydraulic cylinder barrel, which defines the piston area. The bore area determines the extend (push) force: F = P × A_bore. Larger bore diameters provide more force at the same pressure.

Practical Note

Common metric bores: 32, 40, 50, 63, 80, 100, 125, 160mm. Common imperial: 1.5, 2, 2.5, 3, 4, 5, 6 inches. Select based on force requirements and available pressure.
