Plain Bearings
Therefore, the journal (i.e., the part of the shaft in contact with the bearing) slides over the bearing surface.
The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on or the ways on the bed of a lathe.
