A bearing assembly can support a rotating shaft on a vehicle structure and can include a rolling element bearing that has an inner race configured to be press fit on the rotating shaft. An outer race can surround the inner race and be configured to be mounted on the vehicle structure. A plurality of rolling elements can be located between the inner race and the outer race. A retaining ring can be configured to be press fit on the rotating shaft and abut the inner race when the rolling element bearing and the retaining ring are press fit on the rotating shaft. The press fit between the retaining ring and the rotating shaft can contribute to the press fit between the inner race and the rotating shaft such that the retaining ring and the rolling element bearing together distribute a load input by the rotating shaft to the vehicle structure.

A hub bearing unit includes an inner ring having inboard and outboard axial ends and a bearing inner race on an outer surface. An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis and the other ring is fixedly coupled with a frame. An annular displacement limiter extends radially from one ring and has a circumferential stop surface spaced radially from a surface of the other ring. The stop surface engages with the ring surface when the ring displaces radially relative to the other ring. A seal includes an annular sealing member coupled with one ring and is sealingly engageable with the limiter or is mounted on the limiter and sealingly engageable with one ring or a rigid seal member coupled with one ring.

An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis and the other ring is fixedly coupled with a frame. A plurality of rolling elements is rollable upon the inner and outer races. A displacement limiter extends radially from one ring and has a frustoconical stop surface spaced radially from a surface of the other ring. The limiter stop surface engages with the ring surface when the ring displaces radially and/or axially relative to the other ring to prevent brinelling impacts on the bearing races. Preferably, the displacement limiter is located axially between the rolling elements and the ring inboard ends.

An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.

Provided is a seal for a bearing arrangement for sealing an interior space between at least two parts of the bearing arrangement rotatable relatively to each other, and in which the interior space contains a lubricant, whereby the seal includes a seal part which is shaped for conveying the lubricant with a direction component pointing into the interior space.

A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. The cage includes an annular portion and a plurality of cage bars. Each of the balls is received a pocket between each pair of cage bars that is adjacent in the circumferential direction. A portion of the pocket in a second axial direction opens with a dimension that is smaller than a diameter of the balls. The cage bar includes a flat surface that is continuous with an inner peripheral surface of the annular portion, and an inclined surface that extends away from the inner ring toward the second axial direction from the flat surface.

A bearing includes an outer ring with a first outer roller race, a second outer roller race, and a radially inward facing outer ball race. The bearing includes a first and second inner rings that axially abutting one another at an abutment interface. The first inner ring has a first inner roller race, the second inner ring has a second inner roller race that are disposed in an interior area coaxially with the outer ring. A plurality of first rollers rollingly engage the first outer roller race and the first inner roller race. A plurality of second rollers rollingly engage the second outer roller race and the second inner roller race. A plurality of balls rollingly engage the outer ball race and the inner ball race.

Preferably, the displacement limiter is located axially between the rolling elements and the ring inboard ends.

A sealing device for a hub/wheel assembly with a roller bearing. The sealing device includes a guard, made of plastic. The guard is coupled to an outer ring of the bearing to seal off the bearing. The guard has a cylindrical mounting wall with an outer lateral surface coupled to an inner lateral surface of a collar of the outer ring, and a snap-engagement step for engaging with the collar made along the outer lateral surface so that it snap-fits in a contoured annular groove made along the collar about the axis. An annular gasket is made of elastomer and co-injection-molded inside an annular groove made in the cylindrical mounting wall on the same side as the snap-engagement step.
