In the field of mechanical structure, it is often necessary to install two moving parts together, because the mutual movement of the parts and the parts will cause friction, so the use of soft connections can reduce wear and tear, and even if wear and tear causes damage, it is more convenient to replace , cheap, so the application of "industrial bushing" was born.

The bushing on the car is mainly installed on the chassis, because there are various suspensions and control arms under the chassis, and these parts are connected by the rotating shaft, in order to reduce the mutual wear between the parts, so the suspension system of the car is in the middle Both use a large number of automotive bushing to connect.
