Ceramic ball bearings are applied in high-performance applications. They have a lower friction at high rotation than traditional bearings. This partially due to the characteristics of silicon nitride and partially due to the tight tolerances of the balls used. Silicon nitride and zirconium oxide are the most common material used for ball bearings. In some cases, a PEEK cage is used to position the precision balls.

Benefits of ball bearings:

• Lower friction
• Non-magnetic
• Longer lifetime
• Less weight
• No lubrication needed
