The WON linear bearings generate lower friction than comparable sliding bearings. With less friction to overcome, less power is required to move a load, higher speeds can be achieved, and greater ...

For high-speed machining centers and milling spindles, the KTNHA/HC5-SP are single-row, silicon-nitride, cylindrical-equipped roller bearings. According to the manufacturer, the bearings' centrifugal ...

New geometries like gothic arch and elliptical contact profiles increase load capacity without enlarging bearing size. Advanced materials such as silicon nitride ceramics and hybrid steels reduce ...

Scientists at the Department of Energy’s Oak Ridge National Laboratory have invented a coating that could dramatically reduce friction in common load-bearing systems with moving parts, from vehicle ...

Although replaced in recent years by roller bearings, friction bearings (also called solid bearings or plain bearings) were a railroad standard for many years. Friction bearings were blocks of metal, ...
