A bearing assembly includes an inner bearing ring, an outer bearing ring and rolling bodies located between the inner bearing ring and the outer bearing ring. A gap is defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring. The radially inner surface of the outer bearing ring includes a first radial surface portion that is offset a greater distance from a center of the bearing than a second radial surface portion. The first and second radial surface portions are connected by a sloped surface. A sealing arrangement located in the gap. The sealing arrangement includes a first annular body including an elastomeric sealing protrusion to contact the sloped surface of the outer bearing ring.

A method for manufacturing a hub unit includes: preparing a hub unit intermediate including an inner shaft, an inner ring fixed to an axial end of the inner shaft, and an outer ring rotatably arranged with respect to the inner shaft and the inner ring; preparing a magnetic seal member including a seal member and an annular magnetic member having no magnetic pole; and arranging the magnetic seal member between the inner ring and the outer ring of the hub unit intermediate. The method further includes: forming splines extending along the axial direction by cutting the inner circumferential surface of the inner shaft of the hub unit intermediate in which the magnetic seal member has been arranged; and forming magnetic poles in a circumferential direction of the magnetic member of the hub unit intermediate in which the plurality of splines have been formed.

A wheel bearing unit includes an outer ring, a first inner ring with a first axial end face, first rolling elements arranged between the outer ring and the first inner ring, a second inner ring with a second axial end face, facing the first axial end face, second rolling elements arranged between the outer ring and the second inner ring, and a sealing device for sealing an interface of the first inner ring and the second inner ring. The sealing device includes an annular retaining element and a sealing element provided on the annular retaining element. The sealing element is a sealing ring that includes first and second contact points contacting the annular retaining element, a third contact point contacting the first inner ring, and a fourth contact point contacting the second inner ring. At least one of the contact points has a flat face.

A bearing includes a first ring, a second ring and a plurality of rolling elements between the first and second rings. The first ring is a split ring formed of a first ring part and a second ring part that meet at a joint region, and each of the ring parts includes a recess that extends axially into the respective ring part from the joint region. A cylindrical seal is disposed in the recess of the first ring part and extends across the joint into the recess of the second ring part.

The rolling bearing for a blade root includes an outer ring (13) and an inner ring (12). An inner space (43) is defined between the inner surface (33) of the outer ring (13) and the outer surface (25) of the inner ring (12). At a distal end (46), the inner space (43) is closed off by a distal sealing system (47) between the outer ring and the inner ring. A system (57) for retaining the distal sealing system (47) includes a retaining body (58), and a thread/tapping system provided on a peripheral assembly surface of the retaining body and on a peripheral surface of the facing inner or outer ring. The retaining body (58) is screwable into a retention position in which an axial abutment surface (61) of the retaining body forms an axial stop for the distal sealing system longitudinally (B), in the proximal->distal direction.

A method for replacing an existing radial seal positioned around a shaft and adjacent to a bearing includes providing at least one spacer in a seal cavity of the existing radial seal. The method also includes removing a cover of the existing radial seal. The method further includes removing the at least one spacer. In addition, the method includes removing the existing radial seal from around the shaft. Moreover, the method includes replacing the existing radial seal with a new radial seal. Further, the method includes moving the spacer(s) from a first side of the seal cavity to an opposing, second side of the seal cavity to provide a new sealing location for the new radial seal. Thus, the method also includes securing the cover adjacent to the new radial seal.

A retainer is rotationally driven about a axis of a ball bearing, and convex areas having pockets provided therein along a ball pitch circle of the retainer and concave areas between adjacent pockets is detected by a sensor. Grease is discharged according to phases of the convex areas and concave areas in the rotationally driven retainer from a dispenser having grease discharge ports arranged to face an annular space.

According to one embodiment of the present disclosure, a sealing device of a wheel bearing may be disposed axially outside of rolling elements and may be mounted between an outer ring and a hub. The sealing device of the wheel bearing may comprise an outer ring slinger mounted on the outer ring, a hub slinger mounted on the hub, and a deviation-preventing protrusion which protrudes from an outer circumferential surface of the hub to hold an axial inner end of the hub slinger when the hub slinger moves inward in an axial direction. The outer circumferential surface of the hub may meet the deviation-preventing protrusion at right angles.

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.

A sealing assembly for a cup bearing of a universal joint includes a seal sub-assembly configured to be positioned in a space between a cup of the cup bearing and a trunnion of the universal joint. The seal sub-assembly includes an elastic sealing member configured to contact an outer surface of the trunnion, and a seal insert attached to the elastic sealing member and configured to contact an inner surface of the cup. The seal insert includes an extension portion configured to contact and extend away from a rim surface of the cup. The sealing assembly further includes an external shield including an inner portion and an outer portion. The inner portion is configured to contact the outer surface of the trunnion, and the outer portion is attached to the extension portion of the seal insert.
