Abstract: 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.

Abstract: The invention relates to a planet carrier (1) with planet pins (2) that are supported in at least one wall section (10) of the planet carrier (1), the planet carrier (1) having at least one axial bearing (6) supported on the wall section (10), with the axial bearing (6) being supported on the wall section (10) by means of at least one axial disc (9), the planet carrier (1) furthermore having at least one lubricating oil feed (11) overlapping the planet pins (2) to the planet pins (2), with the lubricating oil feed (11) having at least one oil retaining disc (13, 22) located on the planet carrier (1) and thus overlapping the lubrication openings (12) to the hollow planet pins (2).

Abstract: A rotating passage feed system for admitting pressure means into two machine parts (hub part (2), shaft (3)) which rotate relative to one another about a common axis. Conduits (17) that convey the pressure means are located in the shaft (3) and are joined to pressure means connections (6) via tapped holes while a connecting part (5) in which ring channels (8) are provided is also joined thereto. A central sleeve (9) is joined to the connecting part (5) in a non-rotatable manner. The connecting part (5) and the central sleeve (9) are produced in an inexpensive manner as lightweight structure formed from sheet metal through a shaping process.

Abstract: A planet gear pin (4) is secured against axial displacement relative to a planet gear carrier (1) using an elastically deflectable or deformable retaining element (9, 9a, 9b) arranged in a location hole (10) in the planet gear pin (4).

Abstract: An angular thrust disc has a Z-shaped cross sectional profile, a free end of whose radially outer angular portion comprises radially inward directed projections arranged axially spaced from a free end thereof and made by chipless stamping, which projections engage into a peripheral groove of a shaft or a housing, and a free end of a radially inner angular portion of the angular thrust disc comprises circumferentially spaced and radially outward directed crimpings and recesses which form an installation safeguard and permit an admission of oil into the thrust bearing.
