Since a sheet metal spinner plate on the wheel flange leads to a better sliding sealing contact than the usually untreated wheel flange inner side, a spinner plate is mounted adjacent to the wheel flange before installation of the wheel bearing on the wheel hub.

In this way it is possible to dispense with a special design of the centrifugal plate and the wheel bearing flange as well as the bearing part, as provided by DE 10 2013 218 635 A1, in order to achieve a reliable, stationary fit of the centrifugal plate.
