摘要： This invention relates to an improved vehicle wheel hub (12) and bearing unit assembly (10) and method for producing the same wherein an outer brake rotor mounting surface of the wheel hub and bearing assembly is subjected to a microfinishing process. The method for producing the vehicle wheel hub and bearing assembly comprises the steps of: (a) providing a vehicle wheel hub (12) including an inboard end (16), an outboard end (18), and a main body (20) having a radially outwardly extending flange (22), the flange having an outer surface which defines an outer brake rotor mounting surface (22B) of the vehicle wheel hub; (b) providing a bearing unit (10) to rotatably support the vehicle wheel hub relative thereto; (c) assembling the bearing unit onto the vehicle wheel hub to produce a vehicle wheel hub and bearing unit assembly which defines a longitudinal axis (X); (d) preloading the bearing unit; (e) providing a microfinishing assembly (50) having a microfinishing wheel (52); (f) supporting the vehicle wheel hub and bearing assembly (10) on the microfinishing fixture; and (g) operating the microfinishing fixture (40) whereby the microfinishing wheel (52) engages the outer brake rotor mounting surface (22B) of the vehicle wheel hub and bearing unit assembly (10) to produce a finished vehicle wheel hub and bearing assembly, the outer brake rotor mounting surface of the finished vehicle wheel and bearing unit assembly being microfinished relative to the longitudinal axis of the vehicle wheel hub and bearing unit assembly.
