<p>PURPOSE: To provide a unitized wheel hub and bearing assembly for use on the ends of stationary axles and particularly on tractor and trailer axles. CONSTITUTION: A wheel hub 12, a pair of bearings 14, 16 and at least one seal 18, 20 are assembled with a mounting sleeve 22 which is sized to be capable of being fitted on the end 40 of an axle. The inclusion of a custom designed mounting sleeve permits the structure of unitized assemblies to be used with existing axles as well as with new ones. This unitized construction allows pre-adjustment of the bearings and when two seals are employed, the bearings can also be prelubricated.</p> |
