Overview

Sintered bronze straight bushing

SKF sintered bronze straight (cylindrical) bushings are suitable for rotating, oscillating and linear movements, and can accommodate radial loads. SKF sintered bronze bushings are self-lubricating and maintenance-free. They consist of a porous bronze matrix that is impregnated with mineral oil. The oil impregnation enables very high sliding velocities and makes these bushings suitable for rotating applications.

Key features

Low coefficient of friction
Very high sliding velocity

Typical applications

Hydraulic cylinder rod ends
Construction machinery linkages
Agricultural joints
Industrial pivot structures

Selection guidance

Check load direction, oscillation angle, relubrication access, sealing need, ring material, and mounting dimensions.
