the figure shows a flat Diohtsoheibe 1 made of elastic, oil-resistant Material (e.g. plastic) «a U-shaped seat on the shaft 2 Thrust ring 3 and the ring 5 pressed in the groove 4 in the outer race, U-shaped Retaining ring 6. Only the one on the outside of the bearing, initially axially or diagonally, is used to assemble the outer retaining plate Flange of the retaining ring (indicated by dashed lines in the drawing) naoh Insertion into the mounting groove on the inside of the bearing in its end position pressed (shown in solid lines in the newspaper). The pressure pressure of the flat Diohtsoheibe 1, which according to the innovation on both, radially dispersing Borders 7 of the thrust ring 3 rests in a sliding manner in the axial direction, can be adapted to the respective requirements by moving the U-shaped stop ring 3 axially on the shaft 2.

The advantages of the present innovation are that here a sliding contact takes place on both front sides of the diaphragm disk, which ensures a long-term, good seal, and even if it becomes brittle of the Diohtungswerkstoffs get a very effective labyrinth seal remain. In addition, the U-shaped thrust ring not only serves to seal both sides, but also acts as one Slinger off. On the one hand, the run-up ring, which is now U-shaped, hurls the water that hits it from the outside (resp. Dirt), i.e. it keeps it away from the actual sealing surface and, on the other hand, is caused by the radial one on the inside of the bearing Board prevents the grease from escaping close to the outside. After all, such a wire arrangement is cheap to manufacture and, as described above, easy to assemble.

Of course, the idea of innovation is not limited to what has been explained and in the drawing illustrated embodiment of a water pump bearing, but can be used mutatis mutandis for sealing an annular gap in shafts, roller bearings and the like. It does not matter whether the Diohtsoheibe comes into sliding contact on the outer edge or on the inner edge.
