💡 What is a ball bearing used for in industrial machinery?

In general, bearings support rotating shafts and minimize friction in mechanical systems.

• Helps carry radial and axial loads
• Improves efficiency by reducing wear
• Available in steel, ceramic, and hybrids for different temps
• Selection depends on load, speed, lubrication, and enclosure
