The auxiliary ring may include a seal assembly and may be connected to the at least one outer ring with a snap fit.

Rolling-element bearing unit and assembly method

A wheel bearing unit includes an outer ring and first and second inner rings and a plurality of rolling elements disposed between the inner and outer rings. At least one of the inner rings has an annular groove formed between an axially outer end of its radially outer surface a radially outer end of its outwardly facing axial end. A seal element such as an O-ring is mounted in the annular groove, and the O-ring is configured and mounted such that a first portion thereof extends axially outwardly of the first outwardly facing axial end and a second portion of the O-ring extends radially outwardly of the radially outer surface.

Wheel bearing unit and pre-assembly method

A rolling-element bearing unit for a wheel bearing assembly of a vehicle includes a rolling-element bearing with an outer ring, a an inner ring, a bearing interior between the outer ring and the inner ring and a plurality of rolling elements in the bearing interior. The inner ring has an inner ring surface facing the bearing interior and a first and a second axial end surface. A first seal assembly includes a retainer fixed on the bearing outer ring and a seal element configured to slidingly seal against the bearing inner ring surface or against a slip sleeve carried by the bearing inner ring. The retainer is an angle bracket having an axially extending annular leg and a radially inwardly extending annular flange, and radially inwardly extending flange projects radially inwardly beyond the bearing inner ring surface, for example, over a step in the first axial end surface.

Rolling-element bearing unit for wheel bearing assembly

A rolling-element bearing unit for a wheel bearing assembly of a vehicle includes a first rolling-element bearing having an outer bearing ring and an inner bearing ring and rolling elements disposed between the outer bearing ring and the inner bearing ring and a first seal element having a seal-element base body having a first support member mounted to an axial outer surface of the inner bearing ring and a first seal lip pressed against a radial end surface of the outer bearing ring to hold the outer bearing ring in position relative to the inner bearing ring. Also a wheel bearing assembly including two such rolling element bearing units.

Rolling-element bearing unit

A bearing unit configured to support a first component for rotary movement with respect to a second component includes a first bearing having an inner ring and an outer ring and a second bearing having an inner ring and an outer ring and a separator axially disposed between and connecting the outer ring of the first bearing and the outer ring of the second bearing in an interference fit manner or in a friction fit manner to form a preassembled unit. The separator may be annular and have a plastic base body with axial openings in which metal spacers, cylindrical rods, for example, are mounted.

Bearing unit and separator

A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.

Pin for guiding a gear wheel, and planetary transmission containing the same

A bearing device includes a first bearing element and at least one second bearing element that is movably supported relative to the first bearing element and at least one seal unit that includes at least one attachment element that plays a role in attaching at least one seal element of the seal unit to the first bearing element. The attachment element includes at least a part of an antilock braking system (ABS) ring. The ABS ring may include through openings and be usable with a sensor that senses a magnetic field generated by the ABS ring.

Bearing device and manufacturing method thereof

A bearing arrangement is provided with an area to be supplied with lubricant from a lubricant reservoir via a lubricant line. The lubricant reservoir has a number of individual reservoirs in which a portioned amount of lubricant is contained with closure to the lubricant line. A mechanism is provided for allowing the closure to the lubricant line to be optionally cleared.

Bearing arrangement

A guide rail for a linear bearing has at least one rail element with a guideway for rolling bodies. The rail element is connected to a plastic body or borders the plastic body, with the plastic body forming the base body of the guide rail. To increase the precision of the guide rail, especially when used in an environment involving a wide temperature range, the rail element is connected to a metallic support frame which is surrounded at least partially by the material of the plastic body.

Guide rail for a linear bearing

An injection molding tool for producing a cage for a linear bearing in which several rolling elements are positioned in the cage in the direction of its longitudinal extent in the assembled state includes two tool halves each provided with protrusions. The protrusions extend into the cavity of the tool during the injection molding process and form a portion of a receiver pocket for receiving a rolling element. To make the injection molding process simple and economical, the protrusions are fixedly connected with the tool halves, with the protrusions being are shaped in such a way that, when acting together, they form holding elements for retaining the rolling elements in the receiver pockets in the cage when the injection molding tool is closed. The holding elements are thus integrated into the basic geometry of the cage. A rolling bearing cage for a linear bearing is provided with a plurality of receiver pockets for holding rolling elements next to each other in a manner arranged along the longitudinal extent of the bearing. The cage is also provided with holding elements integrated into the basic geometry of the cage for retaining the rolling elements within the receiving pockets.

Linear guide assembly comprising at least two guide rails, which are moveable in the longitudinal direction with respect to each other and have prismatic shaped raceways, a plurality of rolling elements guided in a cage, at least one gear wheel for the positive guidance of the cage is connected to the cage, which wheel engages in toothed racks, each of which is connected to a guide rail, the gear wheel comprising a disk, having axial projections distributed around the periphery at least one of the end surfaces and rows of uniformly spaced recesses, into which the projections on the disk can engage.

Linear guide assembly with positively guided cage

A bearing unit includes a housing provided with a cylindrical bore and a linear bearing positioned within the cylindrical bore. The linear bearing includes a cage in which are arranged a plurality of endless ball rows each defined by a longitudinally extending ball track for load-bearing balls, a longitudinally extending return track for non-load-bearing balls, and deflection tracks connecting ends of the longitudinally extending ball track and the longitudinally extending return track. Each longitudinally extending ball track opens radially outwardly with a track plate being arranged to cover the longitudinally extending ball track for the load-bearing balls. The cylindrical bore of the housing is provided with a plurality of recesses each located in an area of the cylindrical bore facing one axial end of one of the track plates to permit radial deflection of the one axial end of the track plate.
