    groove ball bearings are the most common type of bear-ing, and can handle both radial and thrust loads. Due to their low-frictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the ball and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and
