8 Wheel Hub Bearings - Scroll Down

Wheel hub bearings are sealed rolling-element bearings fitted in a kart wheel hub so the hub can rotate on the axle or stub with low friction. They are specified by inner diameter (common kart sizes include 17 mm, 5/8 in, 3/4 in, and 25 mm), outer diameter, and width to match the hub bore.
