Abstract
A wheel hub and bearing assembly for use on the ends of a stationary axle and particularly on tractor and trailer axles. A wheel hub, a pair of bearings, a bearing spacer and seals are assembled and installed on the axle end. The bearing spacer is positioned between the pair of bearings and has one or more vanes mounted thereon for redirecting the flow of lubricant disposed in a cavity in the wheel hub between the bearings in a bi-axial flow direction towards each spaced bearing to lubricate and cool the bearings.
