💡 What is a ball bearing used for in small mechanical projects? Ball bearings reduce friction, support loads, and enable smooth rotation for high-speed parts. - They’re handy in RC cars, hobby robots, and 3D printers. - They tolerate moderate speeds with low friction for longer life. - Shielded ZZ variants keep dust out and maintenance low. - Pre-lubricated versions get you running quickly without extra grease.
