Ceramic Bearings

ball bearing are made from pure silicon nitride material with extreme high density from uniform compaction (3.25 gcm3). The micro-structural development of this material during manufacture is second to none. These high precision grade 5, si3n4 pure ceramic balls are 51,000,000" from exactly round in sphericity. They are 60% lighter in weight, and 7 times harder than steel. Friction is reduced to near zero. We are dealer, supplier, exporter and all solutions of bearing products with guarantee, warranty assured efficiency, safety and quality.
