High-speed precision ceramic bearings with an inner diameter of 10-60mm can be divided into three precision grades: P4, P4A and P2. The limit revolution can reach 80000 RPM. The rotating accuracy and service life of bearings are comparable to the world's top brand physical bearings. Si3N4 Silicon Nitride Ceramic Ball: Small starting torque, long service life, high rigidity, high operating accuracy, insensitive to temperature, good self-lubrication, good insulation, good corrosion resistance, good ceramic material, itself has extremely high acid and alkali resistance, strong salt spray resistance, with special alloy steel processing bearing has perfect corrosion resistance and high temperature resistance. Cage using nylon (TYN), phenol resin (TR)PEEK and other engineering plastic material products, self-lubrication performance is good, small friction coefficient, low bearing heat when high-speed rotation, widely used in high-speed machine tool spindle bearing. The size of 70 series ceramic bearing contains all sizes of products from 7001C HQ1/P4(inner diameter:12mm outer diameter:28mm) to 7018C HQ1/P4(inner diameter:90mm outer diameter:140mm)
Feature of Ceramic ball: 1, corrosion resistance, strong acid and alkali, seawater can also be used. 2, light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3. 3, high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3. 4, high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating. Silicon nitride ceramic ball is a kind of precision ceramic sintered at high temperature in non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance. It can be used in seawater for a long time, and has good properties of insulation. At 800 C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of bearing steel. Small weight and small centrifugal force in rotation can achieve high speed operation. It is also self-lubricating, it can be used in the environment without high pollution of lubricating medium. It is the preferred material for ceramic bearings and mixed ceramic ball bearings.
