  • Dynaroll: Ball Contact Angle for Ball Bearings

    Contact angle is the angle between a plane perpendicular to the bearing axis and a line joining the two contact points between the ball and the inner and outer raceways. The initial contact angle ao is defined as the contact angle when the bearing is subjected to a minimal axial load to remove the looseness resulting from radial play.
