💡 What is a ball bearing used for in everyday machinery?
Ball bearings support rotating shafts with low friction and handle radial loads across a wide range of devices. They’re handy in machines where smooth, quiet operation matters.
- reduces friction and supports rotating shafts in many machines - handles radial loads in motors, conveyors, gearboxes, and appliances - shielded design keeps out dust and moisture for longer life - ideal for compact spaces where precise alignment matters
