What are bearings and bushings?

Bushings (also referred to as plain bearings, plane bearings, sleeve bearings or linear sleeve bushings) operate with sliding motion between the moving surfaces. Bushings are selected based on the velocity and the applied load. Maintenance-free bushings do not require additional lubrication to operate.

What is the purpose of a bushing?

It provides an interface between two parts, damping the energy transmitted through the bushing. A common application is in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic rubber or polyurethane) separates the faces of two metal objects while allowing a certain amount of movement.

How do Bush bearings work?

A plain bearing, also known as a bushing, is a mechanical element used to reduce friction between rotating shafts and stationary support members. Typically, a bushing relies on soft metal or plastic and an oil film to support the rotating shaft on the hardened shaft journal.

What is bushing in a car?

CARS.COM — Bushings are cushions made of rubber, polyurethane (often shortened to “poly” or “urethane”) or other materials. They're mounted on car suspension and steering joints to absorb road bumps, control the amount of movement in the joints and reduce noise and vibration.
