Cost performance ceramic bearings are far superior to steel bearings, lifetime use of bearing life than now increased more than 3 times, can save a lot of downtime downtime, reduce scrap, reduce spare parts inventory bearings. Performance comparison with the bearing steel, bearing steel weight is 30% -40%, can reduce the centrifugal force generated by the increase in dynamic physical load and slip. Because of high wear resistance, speed is 1.3-1.5 times the bearing steel, high-speed rotation can reduce the channel due to surface damage. Elastic modulus 1.5 times higher than the bearing steel. Elastic force is small, can reduce the load generated by the high amount of deformation. Hardness is 1 times the bearing steel, can reduce the wear and tear. Compressive strength is 5-7 times the bearing steel. Bearing steel thermal expansion coefficient is less than 20%. Friction coefficient is less than 30% of bearing steel, can reduce friction and heat, reduce heat caused by bearing failure before peeling. Tensile, bending and metal equivalent.
