Title: FACETTED JEWEL BEARINGS. UMMS12-69; Patent 9,678,478.

  • 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 these jewel bearings 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.
