In the gearing transmission, with a gearbox (3), the projecting shaft (1) is keyed to a disc (18) covering the bearing opening at the gearbox (3) with a small running play, and act as a support surface for an axial profile sealing ring (19). The ring (19) has a larger outer dia. than the outer roller bearing (4), and is let into the end side of the gearbox (3). The profile sealing ring (19) is of polyurethane, or similar wear-resistant material, with an outer sealing lip (23). The stripping ring (8) is of polyurethane or the like.
