A wheel bearing for a motor vehicle is provided with an outer ring, an inner ring arranged at least partially inside the outer ring, and with a longitudinal axis extending in the axial direction of the outer ring and of the inner ring from a vehicle inner side to a vehicle outer side. The inner ring is provided with a flange section on its end facing the vehicle inner side having a first section at the point that is farthest from axial center of the outer ring, and with a second section which forms a contact surface for attaching a brake disk. The flange section is formed stepped in such a way, so that the contact surface for attaching the brake disk is arranged offset relative to the section of the flange section at the farthest point from the axial center of the outer ring in the axial direction toward the vehicle inner side, and so that an at least a partially circumferential projection is located on the side opposite the contact surface for attaching the brake disk.

A rolling-element bearing transmission includes a first rolled-on element, at least one second rolled-on element and a third rolled-on element. Each of the rolled-on elements has a raceway configured to support a plurality of rolling elements. A first set of rolling elements is disposed between the first rolled-on element and the at least one second rolled-on element and a second set of rolling elements is disposed between the at least one second and the third rolled-on elements. Each of the rolled-on elements comprises or supports at least one transmission element, and the at least one transmission elements are disposed and configured to form a transmission.

A bearing system includes: a rotatable shaft, a circumferential channel in the shaft with an axially extending profile surface at least part of which is inclined relative to the shaft axis; a bearing, around the shaft in use; a split ring in the circumferential channel in contact with the inclined profile surface, the split ring includes a first part having an outer diameter, and a second part having a greater outer diameter than the first part to provide a thrust surface; a collar, including an internal bore to accommodate the first part of the split ring in use; and a bearing locator for exerting an axial locating force between the split ring and the bearing to locate the bearing on the shaft. An axial thrust load exerted on the split ring by the shaft is transmitted to the collar by the thrust surface, and the split ring is urged along the inclined profile surface so as to produce a radial load on the split ring which is resisted by the collar.

To provide a rolling bearing having excellent rust prevention capability and capable of being used for a long period of time in a highly corrosion environment. A rolling bearing 1 utilized for a power generator which generates power from natural energy or for generator equipment has one or more bearing members which form the bearing having a rust prevention film formed in a predetermined region of a surface of a base material. The rust prevention film is formed by a porous film with a sacrificial anode action against the base material in the whole of the predetermined region. The porous film in a part or the whole of the predetermined region is subjected to sealing treatment which impregnates the porous film with a sealing treatment agent from a surface of the porous film. A surface of a sealing treatment body obtained from the porous film subjected to the sealing treatment is subjected to first coating treatment which coats the surface of the sealing treatment body with epoxy resin coating. A coated surface formed by the first coating treatment is subjected to a second coating treatment which coats the coated surface with urethane resin coating. The sealing treatment agent is formed by diluting the epoxy resin coating at a dilution rate of between 15 and 25%.

A double row ball bearing includes: an outer ring; an inner ring; a plurality of first balls disposed between the outer ring and the inner ring to form a first ball row; a plurality of second balls disposed between the outer ring and the inner ring to form a second ball row having a pitch circle diameter larger than that of the first ball row; an annular first cage having a plurality of first pockets in which the first balls are held; an annular second cage having a plurality of second pockets in which the second balls are held; and an annular portion that covers, together with the outer ring, a portion of each second ball held in the second pocket from the radially outside, the portion being exposed on the outside of the second pocket and oriented radially outward.

A rolling bearing assembly including a nut for providing a preload is disclosed. A first plurality of rolling elements is supported between an inner bearing ring and an outer bearing ring. A first one of the inner bearing ring or the outer bearing ring includes an extension in an axial direction including a first engagement surface, and a second one of the inner bearing ring or the outer bearing ring includes a first axial end face defining a first axial bearing surface. A nut includes a second engagement surface configured to matingly engage with the first engagement surface, and a second axial end face of the nut defines a second axial bearing surface. The first axial bearing surface and the second axial bearing surface form an axial bearing.

Provided is a bearing device for a vehicle wheel comprising: an outer-side seal that is resistant to deterioration over time and can prevent foreign matter. This bearing device for a vehicle wheel comprises an outer-side seal member 7 that closes an outer-side opening end of an annular space formed by an outer ring 2 and a hub ring 3. The outer-side seal member 7 including a core metal 8 which is fitted to the outer ring 2, a seal member 10 which is joined to the core metal 8, and a metal ring 9 which is fitted to the hub ring 3 and with which the seal member 10 is in sliding contact. An annular space S is provided between the metal ring 9 and the hub ring 3, and the annular space S being filled with a sealing material 20.

A drive pinion fastening assembly including a drive pinion, a pinion sleeve, an external spline, and a pinion fastener. The pinion sleeve is disposed on and engaged with the drive pinion. The external spline is formed on one of the drive pinion and the pinion sleeve for engaging the power transmission component. The pinion fastener is disposed on and engaged with the drive pinion. The pinion fastener militates against axial movement of the pinion sleeve with respect to the drive pinion.

A slew bearing that includes an inner ring. The slew bearing also includes a first outer ring positioned about a first portion of the inner ring. The slew bearing also includes a second outer ring operably engaged with the first outer ring, wherein the second outer ring is positioned about a second portion of the inner ring opposite to the first outer ring. The slew bearing also includes at least one set of ball operably engaged with the inner ring and one or both of the first outer ring and the second outer ring. The inner ring of the slew bearing is configured to rotate about the first outer ring and the second outer ring.
