刚刚狗了一下
Bushings are a type of bearing that insulates both moving and stationary parts. You'll usually find bushings used as a casing for a shaft, hinge or pin or in electrical applications, as an opening for a conductor to pass through. A washer is a flat disk installed underneath a nut that distributes pressure.
