An introduction to bearings (January 3, 2005)

Bearings provide either a sliding or rolling contact whenever relative motion exists between parts of a machine. These reduce friction and thus heat generation, thereby longer life for rotating machine elements. There are mainly two different types, plain bearings and anti-friction bearings. Several manufacturing companies like SKF, FAG, NSK, Timken etc. pursue several cutting edge technologies in the field of bearings. This document gives an insight towards different aspects of bearings like types, design considerations, general application, terminology etc.
