A brief examination of the effect of low temperatures on the physical and mechanical properties of engineering materials and cryogenic fluids is used to indicate their influence on the generation and removal of heat at the rubbing surface. A résumé is given of the techniques which have been used in practical applications including typical plain and roller bearing designs. The importance of safety and operational considerations is emphasized. A survey of advanced systems, particularly those associated with extremely low temperatures, is concluded by a prediction of new techniques which might be explored in the future.
