💡 What are the advantages of ceramic balls in bearings?
Ceramic ball bearings offer:

1. Higher speed ratings due to lower rotational mass and friction.

2. Longer life span, especially in poorly lubricated or corrosive environments.

3. No electric arcing, making them ideal for electric motors and sensitive devices.
