hybrid ceramic ball bearing ring material : chrome steel and stainless steel ball material :Si3N4 and ZrO2

Hybrid ceramic ball bearings inside and outside the ring material is generally bearing steel (Gcr15) or stainless steel (9cr18), mainly silicon nitride ceramic balls (Si3N4), Zirconia (ZrO2), alumina (Al2O3) and so on. Si3N4 which is superior overall performance, with low density, high hardness, low friction coefficient, anti-magnetic insulation, wear-resistant, self-lubricating and rigidity and good. Ceramic ball bearings have become the preferred material. Si3N4 ceramics density 3.20g/cm3, than the bearing steel 7.85g/cm3 density is much lower. Therefore, effective inhibition of ceramic rolling physical centrifugal force generated by high-speed rotation and reduce the rolling load. While reducing the rolling body and raceway rotation between the slide to prevent surface damage play a useful role in longer bearing life. Therefore, the ceramic ball bearings are used in the field of choice for high-speed operation, self-lubricating properties of ceramic balls, ceramic ball bearings so you can use high-temperature short of oil in the environment. Can be a high-temperature bearings. For example, high-speed spindle bearing, spindle bearing, dental drill bearing, high-speed grinding bearing, instrument bearings, hard disk drive bearings. Can also be applied such as roller skates, toys, electric model aircraft and civilian products
