Bushingnoun

(mechanical engineering) A type of bearing, a cylindrical lining designed to reduce friction and wear inside a hole, often used as a casing for a shaft, pin or hinge.

Bushingnoun

(mechanical engineering) An elastic bearing used as a type of vibration isolator, commonly made of rubber. An interface between two parts, damping the movement and the energy transmitted.

Bushingnoun

(mechanical engineering) A threaded bushing, is a fastener element that is inserted into an object, usually to add a threaded hole in a softer or thin material.

Bushingnoun

Coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both.
