What is Bushing

Bushing  is a matching part used outside mechanical parts to achieve sealing, wear protection and other functions, and refers to a ring sleeve that acts as a gasket. Corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used.

In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the lower hardness and better wear resistance when designing. The material is a shaft sleeve or bushing, which reduces wear on the shaft and seat.

When the bushing or bushing is worn to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat. Generally speaking, the bushing and the seat use an interference fit, and a clearance fit with the shaft, because no matter what, it is still impossible to Avoiding wear can only prolong the life, and shaft parts are relatively easy to process.
