Bearing Stiffness, Zhejiang Waxing Electromechanical Co.ltd.

10/4/2020· Bearing Stiffness. A second source of motion is elasticity in the bearing itself. For example, the balls in a ball bearing are like stiff rubber, and under load deform from round to a slightly flattened shape. The race is also elastic and develops a slight dent where the ball presses on it. The stiffness of a bearing is how the distance between
