[0002] A bushing is an annular part, also known as a bearing housing, which is an important part for supporting bearings and transmitting bearing loads. The role of the bushing in the mechanical transmission system is to support and slide bearings to prevent premature bearing damage. It can reduce the friction coefficient, lower frictional wear, and prevent excessive heat generation in mechanical transmission.

[0003] In order to ensure the normal operation of the bushing for a long time, regular maintenance is required, including checking the wear condition of the bushing. If there is wear, it needs to be replaced in time. When replacing, an ejection device is needed to take out the bushing from the part.
