Abstract: A planet gear bearing in a planetary gearset including a planet carrier having two side walls which are arranged parallel to one another and accommodate a plurality of planet gear pins in a plurality of axial holes opposite one another on the same axis is disclosed. A plurality of planet gears are rotatably mounted on the planet gear pins by radial rolling-element bearings inserted into central planet gear holes. Stop elements are arranged between the side walls of the planet carrier and the axial sides of the planet gears and act as wear protection of the planet carrier and the planet gears, and as an axial stop for the radial rolling-element bearings of the planet gears. The stop elements are axial needle bearings, which each include an axial bent-up disc and an axial needle ring formed by a plurality of bearing needles and an axial needle cage.

Abstract: an axial cage (1) for cylindrical rolling bodies which substantially is formed of a thin-walled washer (2) with a W-shaped profile, the individual profile legs of which are formed by an inner radial rim (3) formed on the inner edge of the washer (2), an outer radial rim (4) formed on the outer edge of the washer (2) and a U-shaped center crimp (7) connected by way of inner and outer axial profile sections (5, 6) to the radial rims (3, 4) and having the same radial extent as the rims (3, 4). A number of evenly spaced rectangular cage pockets (8) are cut from the central crimp (7) and the adjacent axial profile sections (5, 6), between which pockets an equal number of pocket webs (9) are formed connecting the rims (3, 4) with one another, by which webs the cylindrical rolling bodies (10) are retained in the cage pockets (8) at uniform distances from one another and are also guided in the circumferential direction.

A plurality of planet gears (7) are rotatably mounted on the planet gear pins (6) by radial rolling-element bearings (11, 12) inserted into central planet gear holes (8). The radial rolling-element bearings are permanently lubricated via axial and radial lubricant supply lines (9, 10) within the planet gear pins (6). In addition, stop elements (15, 16) having the shape of annular discs are arranged between the side walls (2, 3) of the planet carrier (1) and the axial sides (13, 14) of the planet gears (7) and are designed as wear protection of the planet carrier (1) and the planet gears (7), and as an axial stop for the radial rolling- element bearings (11, 12) of the planet gears (7).

Abstract: An axial bearing assembly which essentially is formed of two axial rolling bearings (1, 2) between which a circular ring-shaped carrier component (3) is arranged. Each of the axial rolling bearings (1, 2) has a first ring-shaped bearing disk (6, 7) seated against one of the axial sides (4, 5) of the carrier component (3) and a second ring-shaped bearing disk (8, 9) for fastening to additional components of the surrounding construction which are arranged axially on both sides of the carrier component (3) and which each consist of a thin steel plate. A plurality of rolling elements (14, 15) arranged next to each other additionally roll between the axial inner sides (10, 11 and 12, 13) of the bearing discs (6, 7, 8, 9) and are held at a uniform spacing from each other by a respective bearing cage (16, 17) and together therewith form a needle roller and cage assembly (18, 19).

Abstract: A radial cage in which roll forming is carried out in such a manner that straight side sections of all axial crossbars continue to have at least approximately a material thickness of a starting material for the radial cage, while side rings of the radial cage and axial center sections of the axial crossbars are implemented by rolling down during roll forming to each have material thicknesses that are smaller than the material thickness of the straight side sections and that reduce their centrifugal mass.

Abstract: A radial cage in which side rings have a material thickness of a starting material for the radial cage, straight side sections of each axial crossbar are implemented with a greater material thickness that increases their strength, and an axial center section of each axial crossbar is implemented with a smaller material thickness than the material thickness of the side rings, thus reducing centrifugal mass.

Abstract: A radial needle bearing unit for supporting a shaft, which has an outer sleeve with at least one radially inwardly directed rim, and a cage guiding hearing needles. For sealing purposes, a sealing element is disposed in an annular space delimited by the rim and the cage. The sealing element is an outwardly expanding sealing ring made of a polymer material resting radially outwardly against the inner lateral surface of the outer sleeve and radially inwardly against the lateral surface of the shaft, so that a radial/radial seal is formed. The outer sleeve has, at least in one peripheral location, a holding lug which is formed by stamping or cutting and protrudes the lateral surface of the outer sleeve in a spring-loaded manner.
