  • Ball Bearing Geometry Information: Raceway

    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.
