Abstract
A unitized wheel hub and bearing assembly for use on the ends of stationary axles and particularly on tractor and trailer axles. A wheel hub, a pair of bearings and at least one seal are assembled with a mounting sleeve which is sized to be fitted on an axle end. The inclusion of a custom designed mounting sleeve permits the building of unitized assemblies to be used with existing axles as well as with new ones. The unitized construction allows pre-adjustment of the bearings and when two seals are employed, the bearings can also be pre-lubricated.
