Furthermore, the invention relates to a bearing-slinger arrangement with a roller bearing and a centrifugal disc, wherein the centrifugal disc can be pressed by a spring against the rolling bearing, the rolling bearing, the centrifugal disc and the spring in particular on the same diameter of a shaft preferably an electric motor sitting ( an embodiment of the second variant of the invention). The bearing-slinger assemblies described in the invention have at least the following advantages over the prior art.

According to the invention, no elaborate and costly ceramic coating of rolling bearing parts is required in both variants in order to prevent a current flashover. It is in the first variant requires a smaller axial space for fixing the centrifugal disc, as is necessary for an axial clamping connection, because there is no axial force application z. B. is necessary by means of a spring. In both variants, no separate motor shaft is required to fix and position the centrifugal disk. It can waves are used, which have a constant diameter in a respective section and thus are easier to handle in manufacturing and cheaper to manufacture.

Furthermore, the first variant of the invention, ie a preferably radial press connection between the bearing and the centrifugal disc, compared to a simple transverse compression bandage has the advantage that a loss of clamping voltage over a lifetime, a concomitant reduced driving safety and axial positional accuracy of the centrifugal disc, which a flow tendency of the plastic result, counteract by an axial positive engagement and both an outer and an inner radial clamping of the plastic part. Both variants of the invention are also less susceptible to existing particles (wear particles) and / or media (leakage, fluid).
