A deep groove ball bearing providing an inner ring, an outer ring and a plurality of balls being arranged between the inner ring and the outer ring. The inner ring and the outer ring each include a raceway for the plurality of balls. Each raceway encompasses the plurality of balls symmetrically. The deep groove ball bearing is lubricated by a lubricant being arranged on each axial side of the plurality of balls. The raceways are offset in the same axial direction from the axial center of the inner ring and the outer ring such that the raceways are offset to the axial side of the deep groove ball bearing where the shear rate acting on the lubricant is higher than on the other axial side of the deep groove ball bearing.

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.

A cage has an annular portion positioned on an axially first side of balls and a plurality of cage bars provided to extend from the annular portion toward an axially second side. Pockets each housing a corresponding one of the balls correspond to areas each located on the axially second side of the annular portion and between two cage bars adjacent to each other in a circumferential direction. Each of the balls is exposed from axially-second-side ends of the corresponding cage bars over an axially-second-side range. An axial dimension of the range over which the ball is exposed from the axially-second-side ends is 30% or more and 50% or less of the diameter of the ball.

The present disclosure discloses a polymer joining ring for a bearing assembly and is configured to retain a first inner ring and a second inner ring together to the bearing assembly. The polymer joining ring includes an outer surface and an inner surface. The outer surface includes a W or E shaped geometry throughout and includes a pair of flanges extending radially outwards at corners from outer surface, and a semi-circular protrusion extending at middle of the polymer joining ring. The pair of flanges are placed in tapered narrow grooves of the first inner ring and the second inner ring, and the semi-circular protrusion is placed in a triangular shape space produced between the first inner ring and the second inner ring can be tightly connected to each other. The joining ring is made of a polymer material that facilitates ease in assembling and accurate positioning of the inner rings.

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 deep groove ball bearing providing an inner ring, an outer ring and a plurality of balls being arranged between the inner ring and the outer ring. The inner ring and the outer ring each include a raceway for the plurality of balls. Each raceway encompasses the plurality of balls symmetrically. The deep groove ball bearing is lubricated by a lubricant being arranged on each axial side of the plurality of balls. The raceways are offset in the same axial direction from the axial center of the inner ring and the outer ring such that the raceways are offset to the axial side of the deep groove ball bearing where the shear rate acting on the lubricant is higher than on the other axial side of the deep groove ball bearing.

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.

A bearing unit having a radially outer ring provided with at least one raceway, a radially inner ring provided with at least one raceway, at least one row of rolling elements interposed between the radially outer ring and the radially inner ring, at least one containment cage for keeping the rolling elements of the rolling element row in position, and a seal interposed between the radially inner ring and the radially outer ring. An anchoring element mechanically locks the seal in a first seat of the radially inner ring, and the anchoring element is housed in a second seat of the radially outer ring.

A sealing device for a hub/wheel assembly with a roller bearing, the sealing device comprising a guard, made of plastic, which is coupled to an outer ring of the bearing so as to seal off the bearing, and which has a cylindrical mounting wall having an outer lateral surface coupled to an inner lateral surface of a collar of the outer ring. The sealing device includes a snap-engagement tooth for engaging with the collar made along the outer lateral surface so that the snap-engagement tooth snap-fits in a contoured annular groove made along the collar about the axis and an annular gasket made of thermoplastic elastomer being co-injection-molded inside a gripping seat made in the cylindrical mounting wall on the same side as the snap-engagement tooth, substantially at a corner defined between the cylindrical mounting wall and an annular reading wall transverse to the cylindrical mounting wall.
