💡 What is a bearing ball and what does it do?

A bearing ball is a precise rolling element used to minimize friction and support loads in bearings.
- Rolling element in radial bearings reduces friction during rotation
- Materials range from steel (like S-2) to ceramic for different tasks
- Handy in rock bits, drilling tools, linear slides, and precision assemblies
