A bearing bush, also known as a plain bearing or sleeve bearing, is a simple, cylindrical component used to reduce friction between two moving parts. It consists of a cylindrical inner surface, an outer surface, and a lubrication film between them. Bearing bushings are often made from materials like bronze, brass, steel, or polymer composites.

There isn’t really a difference: a bushing is a type of bearing. In general, a “bearing” facilitates movement between two parts while reducing friction. Simple in design, the typical bearing has two surfaces that roll over each other, enabling two mating components to move friction-lessly.

Bushings, (sometimes called plain bearings, plain bushings, or sleeve bearings) reduce friction between two surfaces sliding against each other. What is a Bushing? Bushings are akin to thin tubes most commonly used for machinery with rotating or sliding shafts to improve efficiency and reduce vibration and noise.

A plain bearing, commonly referred to as a bushing, is a mechanical component used to reduce friction between rotating shafts and stationary support members. Bushings typically rely on a combination of soft metal or plastic and an oil film to support the rotating shaft on the hardened shaft journal.

Bushing – commonly referred to as sleeve bearings, is a cylindrical element built to support loading on an operational shaft that glides back and forth between the moving surfaces. A bushing is a single-element component that may be constructed from a variety of materials.
