Most bearings consist of a relatively limited number of alloys, porous metal, plastics, or other nonmetallics.
Most bearings consist of a relatively limited number of alloys, porous metal, plastics, or other nonmetallics. No material is equally good with respect to all bearing requirements, so selection is a matter of judgment based on essential factors. Materials and processes are constantly raising and broadening the operating limits of all bearings, so existing designs can often benefit from periodicreviews of the latest state of the art.
