💡 What is a ball bearing used for in machinery and how to pick the right one?

Ball bearings reduce friction and support loads in rotating parts. Here are quick considerations:

• bearing type: double-row deep groove offers higher radial load capacity
• size and rating: match bore, outer diameter, and width to shaft and housing
• material and lubrication: chrome steel with grease or oil lubrication
• seals vs open design: open bearings allow lubrication access; sealed variants protect from contamination
