Hybrid bearings have so far been equipped with ceramic balls only. CeramTec has now developed the "Cyrol®" product range and thereby broadened the application portfolio of hybrid bearings to include roller bearings. After the development of the production technologies for roller elements, CeramTec is able to produce needle, cylindrical, tapered and spherical rollers. Manufacturers of roller bearings or linear guides benefit from their special quality and price-performance structure. Instead of high-priced solutions and special applications, they can now offer their customers high-performance...
