A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.

A device for stabilizing pressure inside a gear's housing or a wheel's hub includes a bladder, and a conduit coupled to the bladder and coupleable to a volume containing a lubricant. The bladder includes a chamber having a volume, and is configured such that the chamber's volume increases as a fluid enters the chamber, and decreases as fluid leaves the chamber. The conduit includes a first end positionable adjacent the lubricant containing volume, a second end coupled with the bladder, and a passage between the first and second ends, and is configured to hold fluid disposed in the passage and direct the fluid between the first and second ends. When the conduit is coupled to the lubricant containing volume, the volume of the bladder's chamber, the passage of the conduit and the lubricant containing volume are isolated from the ambient environment.

A manufacturing method of a wheel bearing device, the wheel bearing device including an outer ring member, an inner shaft member that includes a shaft portion that has an inside raceway and a flange portion, a plurality of rolling elements, a seal provided at an end portion of the outer ring member on the first axial side and including an axial lip, and a lip contact surface provided on the side of the inner shaft member and contacted by the axial lip, includes: processing the outside raceway with a distance in an axial direction from a first reference position being managed, a first reference position being set on the outer ring member; and providing the seal at a predetermined position, in the axial direction, of the outer ring member with respect to the first reference position.

Disclosed is an assembly to be mounted at an end portion of an axle of a vehicle, the axle including a differential carrier housing containing a differential and drive shafts, each having one end connected to the differential and a second end to connect to a wheel of the vehicle. The assembly includes a cover to be mounted at the end portion of the axle and fastened to a wheel hub, and a stop elastically compressible in the axial direction and fastened to the cover so as to face and contact one end face of a drive shaft. The stop includes a first part having a first cross-section S1 and configured to absorb in compression axial movements of the drive shaft, and a second part having a second cross-section S2 smaller than the first cross-section S1 and configured to provide a substantially point contact with the drive shaft end face.

A hub structure includes an axle housing, a hub having an insertion hole in a vehicle width direction through which the axle housing is inserted, and an inner bearing disposed between the hub and the axle housing in the insertion hole and rotatably supporting the hub with respect to the axle housing, and an oil seal disposed between the hub and the axle housing in the insertion hole on an inner side relative to the inner bearing in the vehicle width direction. A spacer is provided between the inner bearing and the oil seal in the insertion hole. The spacer has an outer end surface that is contactable with an inner end surface of an inner race of the inner bearing.

A bearing assembly configured to rotationally support a first component relative to a second component includes at least one bearing and at least one closure element configured to close an opening in the first component, which opening is disposed axially adjacent to the bearing. The closure element may be a cured body of foam that conforms to the shape of the opening or a ring mounted on the first component such that it covers the opening.

A wheel hub having an axis of symmetry and including a flange transverse to the axis of symmetry and provided with a plurality of fixing holes for attaching a wheel, a tubular body extending axially from the flange for supporting a rolling bearing, and a centering device arranged on a side of the flange opposite to that of the tubular body and in a position concentric with the axis of symmetry of the wheel hub, for retaining a wheel rim or a brake disc. The centering device being provided with a given number of flattened areas extending circumferentially and axially on a respective continuous tubular body projecting axially from the flange.

A split torsion axle is configured to provide the advantages of a torsion axle while also allowing for the independent adjustment of related wheel assemblies positioned on opposite ends thereof. The split torsion axle also provides for additional stability provided by having a continuous axle member spanning the width of the trailer or vehicle upon which the split torsion axle is deployed. To provide these capabilities, the split torsion axle comprises a first torsion axle beam and a second torsion axle beam, which are rotatably coupled to one another by a central joint. The central joint comprises a first spindle coupled to the first torsion axle beam, a second spindle coupled to the second axle beam, and a bearing assembly rotatably coupling the first and second spindles to one another. Both the first torsion axle beam and the second torsion axle beam are configured to be coupled to respective wheel assemblies.

The present invention relates to a roller for use in an agricultural or mowing machine, the roller comprising a pair of tapered roller bearings and a pair of roller bearings, wherein the tapered roller bearings are closer to the midpoint of the roller than the roller bearings. An agricultural or mowing machine comprising the roller is also described.
