Product description

The bushing is an annular thin-wall bearing component, usually made of wear-resistant material, used to support and guide the movement of the shaft to reduce friction and wear on the shaft. The bushing can be divided into sliding bushing and rolling bushing

Two types, where sliding bushings use the relative movement of their surfaces to reduce friction and wear, while rolling bushings support and guide the movement of the shaft by applying pressure between the rolling surfaces.

The main production methods of the bushing are casting, forging and machining, etc. The casting bushing is to pour the molten metal into the mold, get the bushing blank after cooling and solidification, and then complete the production through machining and heat treatment and other processes; Forging bushing is the metal blank is placed under the forging hammer or press to forge, in order to obtain the desired shape and size of the bushing blank; Machining bushing is the use of lathe, milling machine and other mechanical processing equipment to cut the metal blank to get the desired shape and size of the bushing.

The role of the bushing is mainly reflected in the following aspects:

Support and guide the movement of the shaft to reduce the friction and wear of the shaft.

Protect the shaft and extend the service life of the shaft.

As a guiding device of the shaft, it improves the straightness and rotation accuracy of the shaft.

As a buffer device for the shaft, it absorbs shock and vibration to improve the working stability and reliability of the machine.

In addition, the bushing can also be used as a seal to enhance the tightness and reliability, improve the tightness and wear resistance of the seal, and extend the service life. In some applications, such as valves, bushings are usually made of rot-resistant materials such as teflon or graphite for sealing purposes
