Additional Description

SKF-Bearing 30209 J2/Q

There are several common layouts of ball bearing, each offering various tradeoffs. They are able to be made from a variety of substances, including: stainless steel, chrome steel, and ceramic (silicon nitride (Si3N4)). A hybrid ball bearing is a bearing with races and ceramic balls of metal.

Axially asymmetric races are used by an angular contact ball bearing. An axial load passes through the bearing in a straight line, whereas a radial load takes an oblique course that will need to distinguish the races. So the angle of contact on the inner race is just like that on the outer race. In high speed applications, like jet engines, turbines, and dentistry gear, the contact angle is changed by the centrifugal forces produced by the spheres at the inner and outer race. Ceramics including silicon nitride are now routinely used in such applications because of the low density (40% of steel). These substances reduce work and centrifugal force well. In addition they often wear in the same way to bearing steel—rather than breaking or shattering like porcelain or glass.
