  • Non-lubricated rolling element ball bearing
    Patent number: 6318899
    Abstract: An all-ceramic rolling element ball bearing assembly utilizes the superior compressive strength and hardness of ceramic materials over bearing steels to provide a point contact load bearing interface between the bearing balls and races that has no relative motion in the ball/race contact zone. Without the frictional heating of a curved-line contact bearing design, the all-ceramic bearing does not require the use of a friction reducing lubricant.
