Ball Bearing ComponentsBall bearings are comprised of four major parts: a large ring (outer ring), a smallring (inner ring), balls between the rings (steel balls), and a cage to prevent theballs from hitting each other. The modern structure dates back to around 1500, whenLeonardo da Vinci invented ball bearings to reduce friction against the axles ofhorsedrawn carts. For more than 500 years, the ball bearing has been defined by this simple structure. ProductSiteLaunchDate : 2024-04-06T09:37:32.010Z Size : F679ZZ P5 10PC UnitCount : 1
