A sealing device for a bearing unit, the device comprising:
- a stationary part comprising:
- a first metal shield,
- an elastomer coating co-molded on the first metal shield,
- at least one contacting lip, wherein the at least one contacting lip is radially internal of the first metal shield, wherein the elastomer coating comprises the at least one contacting lip;
- and
- a rotatable part comprising:
- a second metal shield on which the contacting lip makes a sliding contact,
- wherein the second metal shield comprises a plurality of flow baffles positioned at least on an axially exposed surface of the second metal shield, wherein the plurality of flow baffles are shaped as recesses on the axially exposed surface of the second metal shield and distributed along a radially outer peripheral edge of the second metal shield;
- wherein the flow baffles are uniformly distributed along the radially outer peripheral edge of the second metal shield and are configured as plastic deformations of the radially outer peripheral edge of the second metal shield.
