Kart Axle Bearings, Axle Keys & 50mm Sprocket Hub | SVKarting

Rear axle parts for 30 mm, 40 mm and 50 mm axles. Heat-treated, low-drag axle bearings in all three sizes, precision machined 50 mm axle keys for OTK, Parolin and KR karts, and the threaded aluminum 50 mm sprocket hub with a fast-change design that keeps the bolts locked in the carrier.

If the axle does not spin freely and quietly with the chain off, the bearings are costing you speed; most racers replace them at the start of the season and after any bent-axle incident. Rear sprockets and guards are in sprockets and chain guards; seat stays that bolt to the bearing cassettes are in chassis parts.
