Collection: 1-3/8" Axle Bearings

1-3/8 inch axle bearings are rolling-element housings sized for a 1-3/8" (34.925 mm) kart rear axle, a common imperial axle diameter in many racing karts. Free-spin designs let the axle rotate in the bearing with less drag than a locked or seized unit, so the driveline can turn more freely when the kart is rolling.
