💡 What is a ball bearing used for in mechanical assemblies?

This handy guide explains the core roles of sealed ball bearings in hobby and industrial gear.

• Reduces friction between moving parts and supports radial loads
• Helps maintain shaft alignment in compact, space-limited designs
• Durable stainless steel shields resist dust, water, and corrosion
• Pre-lubricated grease ensures ready-to-run performance in RC projects
