A bushings, also known as a bush, is an independent plain bearing that is inserted into a housing to provide a beefing surface for
rotary applications; this is the most common form of a plain bearing.
Common designs include solid (sleeve and flanged), split, and
clenched bushings. A sleeve, split, or clenched bushing is only a "sleeve" of material with an inner dmeter (ID), outer diameter
(OD), and length. 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 extending radially outward from the ID. The flange is used to positively locate the bushing when it is
installed or to provide a thrust bearing surface.
