Ball Bearing Geometry Information: Raceway Curvature, Radial and Axial Play, Ball Contact Angle, Land and Pitch Diameters, Free Angle of Misalignment || Dynaroll Ball Bearings

When a bearing is running under load, force is transmitted from one bearing raceway to the other through the balls. The contact area between a ball and the raceway (contact ellipse) may be very small, so that even moderate loads can produce very large stresses. These stresses can affect bearing performance and life dramatically, so that it is important to consider the internal geometry of the bearing before making a selection for a given application.
