💡 What are the advantages of ceramic balls in bearings?
Ceramic ball bearings offer:
-
Higher speed ratings due to lower rotational mass and friction.
-
Longer life span, especially in poorly lubricated or corrosive environments.
-
No electric arcing, making them ideal for electric motors and sensitive devices.
