Abstract: The invention provides bearing systems characterized by single point contact with each jewel segment and a spring-loaded assembly with protection from radial and thrust forces. An important feature of jewel bearings of the invention is that they are self-lubricating, i.e., no oil or grease lubricants are needed. This can be a major advantage in medical and precision equipment. A secondary important feature is the reduced friction and effective heat-dissipation due to the unique design of the invention with significant reduction in contact surfaces and friction, which significantly prolong the lifespan of the bearings. Another advantage of the present invention is the substantial reduction in audible noise due to the unique design. Furthermore, the invention allows the use of relatively low cost synthetic jewel segments in bearings.
