Electric Motor Bushings

A mechanical bushing is a sleeve-shaped lining which is used to reduce friction and wear between any mechanical parts or constrain the motion of the parts where ever it is installed or applied. The bushing is sometimes called plain bearings; mechanical bushings in an electric motor or any such machinery are used to line a hole in a stationary part of a mechanism and are effective in spreading friction and wear over the surface of the bushing as opposed to directing it to one spot.

Bushings are also used to transfer loads, and in order to minimize vibration, wear and transmission of noise, the bushings are made up of flexible material such as rubber or polythene. These bushings take the form of an annular cylinder of flexible material inside a metallic casting or tube. Bushing is a device used to line an opening, which prevents abrasion to any wires and cables that are being passed through that opening. The compliance of the bushing in different directions has a great effect on ride harshness and handling.
