A slewing bearing includes an inner annular body formed of unhardened stainless steel and coupleable with a fixed member and having an inner race with an unhardened race surface. An outer annular body is disposed about the inner body and is formed of unhardened stainless steel, is coupleable with a rotatable member, and has an outer bearing race with an unhardened race surface and a plurality of gear teeth engageable by a drive pinion to angularly displace the outer body. Rolling elements are disposed between and rotatably couple the inner and outer annular bodies. An annular seal is coupled with the outer annular body and has two opposing axial ends, an axial thickness defined between the ends, a sealing lip engageable with the inner body and an outside diameter and is sized such that the ratio of the outside diameter to the axial thickness is greater than fifty.

A sealing device and a sealing arrangement which creates an improved outer seal in front of the sealing lips, for example, wherein the outer seal can be used in a confined space and affords an enhanced sealing effect for a low coefficient of friction and/or ease of fitting

A slewing bearing includes first and second rings and rolling elements therebetween. The first ring has a shoulder, and a cap is fixed to the first ring that, with the shoulder, defines a radially outwardly facing circumferential groove. A sealing contact member is fixed to a surface of the second ring. A first seal is mounted in the groove, and a sealing member is mounted on the cap. The first seal and the sealing member each include a sealing lip in sliding frictional contact with the sealing contact member.

A centerless grinding processing in which a sliding contact surface (10) is subjected to grinding by pressing a grindstone against the sliding contact surface (10) of an inner ring (3) while rotating the inner ring (3) relative to the grindstone in a prescribed direction, and then, in the centerless grinding process, a finishing step in which grinding lines in a direction intersecting grinding lines formed on the sliding contact surface (10) are formed on the sliding contact surface (10) and/or processing for improving the surface roughness of the sliding contact surface (10) is performed is performed.

A sealing device for a bearing unit, the device having a stationary part provided with: a first metal shield, an elastomer coating, co-molded on the first shield, at least one contacting lip, radially internal, belonging to the elastomer coating. The sealing device having a rotatable part provided with a second metal shield on which the contacting lip makes a sliding contact. The second metal shield is provided with a plurality of flow baffles positioned at least on an axially exposed surface of the shield, shaped as recesses realized through the axially exposed surface and distributed along a radially outer peripheral edge of the shield.

A slewing bearing includes an inner annular body formed of unhardened stainless steel and coupleable with a fixed member and having an inner race with an unhardened race surface. An outer annular body is disposed about the inner body and is formed of unhardened stainless steel, is coupleable with a rotatable member, and has an outer bearing race with an unhardened race surface and a plurality of gear teeth engageable by a drive pinion to angularly displace the outer body. Rolling elements are disposed between and rotatably couple the inner and outer annular bodies. An annular seal is coupled with the outer annular body and has two opposing axial ends, an axial thickness defined between the ends, a sealing lip engageable with the inner body and an outside diameter and is sized such that the ratio of the outside diameter to the axial thickness is greater than fifty.

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 flanged inner ring for wheel hub bearings is disclosed, wherein a tubular supporting body for the bearing is coaxial with an axis (X), and is provided with a flange, transverse to the axis (X), is provided with a plurality of threaded through holes distributed around the axis (X), and is axially delimited by an outer annular mounting surface and by an inner surface axially facing an outer ring of the bearing.

A sealing device and a sealing arrangement which creates an improved outer seal in front of the sealing lips, for example, wherein the outer seal can be used in a confined space and affords an enhanced sealing effect for a low coefficient of friction and/or ease of fitting

The invention relates to a seal device (1) for sealing two bearing elements which rotate relative to each other about an axis (D), in particular for sealing a rolling bearing. The seal device (1) includes a sealing section (2) for sealing purposes and a fastening section (3) for holding the seal device (1) against a bearing element (21). The sealing section (2) is arranged at one end of the fastening section (3) and includes a free end (E) opposite thereof. All the sections (2, 3) have a common carrier element (4) and at least one sealing element (5), and all the sections (2, 3) extend in the radial direction (R) and/or in the axial direction (A). The fastening section (3) extends at least partly in the axial direction (A) such that the carrier element (4) and the sealing element (5) rest directly against a bearing element (21) in order to form a clamping seat in the radial direction (R) by the carrier element (4) in order to hold against a bearing element (21) and a static seal by the seal element (5) in order to seal against a bearing element (21). The invention further relates to a seal assembly (20) for a rolling bearing, in particular for a wheel bearing assembly, including a bearing element (21) and a seal device (1).
