Bearings are used to support rotating parts, such as wheels, axles, or driveshafts. They are available in a variety of sizes and styles to suit nearly any application or driving condition. Bearings are infinitely smoother and more efficient than bushings. Keeping your bearings oiled increases their lifespan and efficiency - use specific bearing oil or any light oil (such as 3 in 1).
