Silicon Nitride Ceramics for Roller Bearing Technology

Using innovative production technologies, CeramTec has succeeded in developing ceramic bearing rollers under the Cyrol brand featuring quality and value that will enable them to open up a broader spectrum of applications. For many years, steel has been the standard in roller bearings. However, advanced ceramics are now becoming an established alternative material. Bearings made from silicon nitride ceramics offer new solutions for difficult bearing situations.

The materials high wear, temperature and chemical resistance properties make silicon nitride ceramics ideal for maintenance-intensive applications. But thats not the only reason. The fact that this ceramic material is an extremely low-friction and non-magnetic material with a very low specific weight, excellent dry running properties and therefore superior emergency operating features is what makes it the material of choice for demanding applications. For example, the combination of specific electrical resistance and low friction make it possible to redefine generators and electrical drive systems. The increased service life of the lubricant is yet another key argument.
