ceramic seal ring, bearing and seal technology can provide economical solutions wherever exact and precise regulation, control, bearings or electrical and thermal insulation are required. Whether in pumps, valves, automotive engineering, medical analysis equipment or even in the fully automatic coffee machines used in homes every day - ceramic seal and bearing components do amazing work behind the scenes. Their excellent performance is attributed to outstanding sliding and sealing properties, dimensional stability and aging
resistance.ceramic seal rings, bearing bushes and bearing sleeves for axial and radial bearings comprises numerous different versions with diameters from just a few to up to 70 millimeters. The materials CeramTec uses here, including alumina, zirconium oxide, silicon carbide and silicon nitride, have a decisive impact on the functionality, reliability and service life of these components. Combined bearings made of ceramic materials and carbon or reinforced plastic are surprisingly light yet very stiff, are not easily impacted by centrifugal forces and feature very good emergency and dry running properties. One example is a radial bearing combined with a ceramic bearing sleeve and a bearing bush made of carbon.
