A bushing, is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications; this is the most common form of a plain bearing. The difference between the three types is that a solid sleeved bushing is solid all the way around, a split bushing has a cut along its length and a clenched bearing is similar to a split bushing but with a clench across the cut.

A flanged bushing is a sleeve bushing with a flange at one end extending radially outward from the OD.
