A radial needle rolling bearing, which has a thin-walled outer sleeve with radial rims that are axially inwardly directed on both sides, a plurality of needle bearings rolling on the inner lateral area of the sleeve and on the outer lateral area of the shaft to be supported, and a cage guiding the bearing needles in the circumferential direction in an evenly spaced manner. At least on one side, in addition to the needle cage, an additional stop disc is inserted into the needle sleeve. The disc is delimits axial movability of the needle cage together with a radial rim or a further stop disc inserted into the sleeve. Between the stop disc and the other radial rim, a sealing element is arranged, which seals the bearing. The sealing element is a labyrinth seal, which can be assembled from two individual mutually engaging sealing rings that have complimentary profile cross-sections. |
