This wheel hub kit replaces wheel hub N15022 used on Bradley Mowers TS2000N and TS2006N sulkies. The hubs feature premium ball bearings that will outlast the original roller bearings multiple times. Unlike the original bearings which wear due to the fact that the bearings are not sealed, these hubs feature bearings that are oversized and sealed. Kit may be used to replace old wheel bearings or to upgrade the wheel bearings on a new sulky.
