Abstract
A method for applying a protective coating to a wheel hub unit includes mounting the wheel hub unit on a platform and applying a layer of the protective coating to a front surface of a mounting flange of the wheel hub unit. A shield covers a central annular portion of the front surface of the wheel hub unit to protect the central annular portion from the layer of protective coating, which can damage markings and magnetic components formed on the central annular portion. A handling arm attaches to the shield to hold the shield in place an axial distance away from the central annular portion of the front face.

A method for applying a protective coating to a wheel hub unit, comprising:
- mounting the wheel hub unit on a platform;
- and
- applying a layer of the protective coating to a front surface of a mounting flange of the wheel hub unit,
- wherein a shield covers a central annular portion of the front surface to protect the central portion from the layer of protective coating.
A wheel hub unit, comprising:
- a radially outer annular element comprising a plurality of first raceways formed on an inner surface of the outer annular element;
- a radially inner annular element comprising a plurality of second raceways formed on an outer surface of the inner annular element;
- and
- a plurality of rolling bodies interposed between the outer and inner annular elements, wherein each rolling body of the plurality of rolling bodies engaged with a first raceway of the plurality of first raceways and a second raceway of the plurality of second raceways;
- engaging the raceways;
- a mounting flange configured to receive a wheel of a vehicle, the mounting flange comprising:
- an axial front surface comprising a central annular portion, the central annular portion comprising at least one marking;
- and
- a layer of protective coating, wherein the layer of protective coating the front surface of the mounting flange, wherein the central annular portion is free of the layer of protective coating.
A system for applying a protective coating to a wheel hub unit, comprising:
- a platform configured to receive the wheel hub bearing;
- a spray nozzle configured to apply a front axial surface of wheel hub bearing with the protective coating;
- a disc-shaped shield configured to cover a central annular portion of the front axial surface of the wheel hub bearing and prevent application of the protective coating to the central annular portion;
- and
- a handling arm configured to hold the disc-shaped shield during application of the protective coating to the front axial surface of the wheel hub.
