The invention relates to a radial needle bearing unit with integrated radial and axial sealing and, optionally, axial support, with an outer sleeve (5) having at least one inward-pointing flange (9) and with a cage (8) which guides the needles (7) and, in conjunction with a stop disc (18) and an elastic ring (17), these being situated within the outer sleeve (5), forms an axial support and an axial seal. In this arrangement, an inner sleeve (6) is provided with at least one outward-pointing flange (12) in the vicinity of an inward-pointing flange (9) of the outer sleeve (5), the cage (8) is provided with at least one outward-pointing flange (14) and is guided in a centred manner in the immediate vicinity of the flange on the inner sleeve (6), and arranged between the flange (14) of the cage (8) and the adjacent flange (12) of the inner sleeve (6) is an outward-expanding sealing ring (17), and arranged between the flange (12) of the inner sleeve (6) and the flange (9) of the outer sleeve (5) is an axial slide ring (18). <IMAGE> |
