High Precision Ultra-fine Grinding 1~15mm Ceramic Ball ZrO2 Ball

Compared with steel balls, the main advantages of silicon nitride ceramic balls are: 1, 59% lighter than the steel ball, greatly reducing the centrifugal force, rolling and wear of the channel when the bearing is running at high speed and acceleration; 2, the elastic modulus is 44% larger than the steel, which means that the deformation is greatly reduced than the steel ball when the force is stressed; 3, the hardness is higher than steel, HRC reached 78; 4, the friction coefficient is small; 5, the coefficient of thermal expansion is 1/4 of steel, can withstand temperature upheaval; 6, easy to obtain almost smooth surface finish; 7, high temperature resistance: silicon nitride ceramic ball at 1050C temperature still has a high strength, hardness; 8, never rust, can work under oil-free lubrication conditions; 9, more chemical corrosion resistance than steel; 10, no metal pollution; 11, non-magnetic; 12. Electrical insulation. 13, there is no adhesion wear;
