Zirconia bearing and silicon nitride bearing are the most commonly used hybrid ceramic bearing. Hybrid silicon nitride ceramic bearing extremely popular in the ceramic bearing with its low density, high hardness, low friction coefficient, magnetoelectricity insulation resistance, wear resistance, self-lubrication and good rigidity. In addition, silicon nitride bearing acid and alkali resistant, resistance to high temperature above 300 degrees Celsius; high wear resistance, high speed, the friction and heat greatly reduced; service life is 3 to 5 times of the usual bearing, weight is 60% lighter than steel, elastic modulus is 50% higher than steel bearing. Hybrid ceramic bearing particularly suitable for high speed, high precision and long life ceramic hybrid bearing steel with the circle of metal (inside and outside) include bearing steel and stainless steel.
