The wind power ceramic ball made of silicon nitride has the advantage of electrical insulation, which effectively avoids the damage of the bearing ring and rolling element caused by the current generated during the running of the bearing. The traditional wind power bearing will have insufficient lubricant after a long time of work, resulting in fatigue damage of the bearing and reduced life, and the self-lubricating function of the silicon nitride ceramic ball bearing itself solves this problem. Even if the wind power bearing seal is very tight, there is still the risk of pollutants entering the bearing chamber, and the silicon nitride ceramic ball has non-magnetic properties, so that pollutants are not easily adsorbed on the rolling body, so that the entire bearing chamber is not polluted by pollutants. The wind power bearing ball produced by our company has a series of advantages such as high hardness, low friction coefficient, light weight, corrosion resistance, non-magnetic, electrical insulation, high temperature resistance and so on, which effectively avoids the electric corrosion of bearings caused by the current generated in the operation of wind power bearing, and lubricating wear problems, etc., is an indispensable material in the field of wind power bearing, and the accuracy level can reach G10. 

The main specifications are: 47.625mm, 50.8mm, 53.975mm.

Advantages of wind power generation bearing ball products: non-magnetic, electrical insulation corrosion resistance, more chemical corrosion resistance than steel hardness is higher than steel, HRC reached 78

The coefficient of thermal expansion is 1/3 of the steel, can withstand the thermal shock at high temperature and metal melt non-adhesion, almost no reaction self-lubrication: no rust, can work under the conditions of oil-free lubrication elastic modulus is 44% larger than steel, the deformation is smaller than the steel ball high temperature resistance: silicon nitride ceramic ball at 1050°C high temperature can still have a high strength, hardness

Long life: the density is 40% of the steel ball, and the friction coefficient is small, which reduces the centrifugal force, rolling and wear of the channel when the bearing is running at high speed and accelerating.
