The presence of lubrication in the ball bearing is essential to reduce the friction and wear between the balls and the raceway. Therefore, the lubrication performance of the ball bearing can be analyzed through numerical simulation models, such as the finite element method, and experimental tests.The wear of the ball bearing refers to the gradual loss of material from the contact surfaces. The wear is mainly caused by the sliding and rolling contact between the balls and the raceway.
