Ceramic Hybrid Angular Contact Bearings

The races and retainer can be made from various steels such as 52100 chrome steel or 440c stainless steel.

Ceramic hybrid angular contact bearings.

Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride si 3 n 4 which make the bearings electrically insulating. Electric current passage is the major cause of bearing damage in wind power generator applications often resulting in premature bearing failure generator breakdown and unplanned turbine down time. These bearings are impervious to corrosion and rarely require lubrication if at all. These bearings make use of both ceramic balls and race.

In some settings only a thin coating of ceramic is used over a metal ball bearing. Ceramic hybrid series angular contact ceramic hybrid bearings are designed such that there is an angle between the races and the balls when the bearing is in operation. Due to the stiffness and hardness of the balls and race these bearings are noisy at high speeds. Electric current passage is the major cause of bearing damage in wind power generator applications often resulting in premature bearing failure generator breakdown and unplanned turbine down time.
