Angular Contact Ball Bearings from Koyo and JTEKT North

This loading (or preload) creates a line of contact (or contact angle) between the inner race, the ball, and the outer race. The preload can be built into the bearing or created when the bearing is Inserted into an assely. The contact angle varies from 15° to 40° and is measured relative to a line running perpendicular to the bearing axis.
