Bore: Diameter 10-500 mm, Tolerance ±0.01 mm

Component Specifications

Definition

A bore is a precisely machined cylindrical cavity within a machine barrel, designed to guide, support, or house components such as pistons, shafts, or plungers. It ensures proper alignment, reduces friction, and maintains operational accuracy in mechanical systems.

Working Principle

The bore provides a smooth, dimensionally accurate surface that allows for controlled linear or rotational motion of internal components, minimizing wear and maintaining system integrity through precise tolerances.

Materials

Typically made from hardened steel, stainless steel, or alloy steel; may include coatings like chromium plating for enhanced wear resistance.
