A system having a rolling bearing providing at least an outer ring, at least an inner ring and at least a seal, which seals an inner space of the rolling bearing on a first axial end of the rolling bearing against ingress of liquids and dust. The system further provides a transportation safety device, which is attached to the rolling bearing and restricts swiveling of the inner ring relative to the outer ring in comparison to a state of the rolling bearing in which the transportation safety device is detached from the rolling bearing.

A bearing assembly includes an outer ring, an inner ring, a cage between the inner ring and the outer ring, a plurality of rolling elements disposed in the cage, and at least one seal unit configured to seal an interior of the bearing assembly on one side with respect to an outer space. The seal unit includes a carrier element and an elastomer element attached to the carrier element, and a ring is mounted axially between the plurality of rolling elements and the carrier element, in the carrier element, for example, which ring is spaced from the cage and distinct from the cage.

A method of making an axle sleeve may comprise forming a main body comprising a cylinder, and forming an expansion member whereby a diameter of the main body may be varied.

A multi-row rolling bearing unit including an outer ring and at least two inner rings, between which rolling bodies are guided, and an elastic securing ring which engages in annular grooves of the inner rings, the securing ring having a U-shaped cross-sectional profile with two flanks which engage in the annular grooves.

An installation unit for installing a bearing unit includes a carrier having an interior and the bearing unit mounted in the interior. The bearing unit includes a first rolling-element row and a second rolling-element row, and both the first rolling-element row and the second rolling-element row are at least partially disposed inside the carrier. The bearing unit is slidingly mounted in the carrier such that, when an end opening of the carrier is aligned with an opening in a bearing housing, applying a force against the bearing unit will slide the bearing unit out of the carrier and into the opening in the bearing housing. Also, a method of installing the bearing unit in the opening in the housing using the installation unit.

A ball joint (100) to be fitted to a knuckle (200) is provided wherein, a shaft section (11) has an annular projection (11a), a dust cover (30) has a seal main body which is made of an elastic body and which integrally includes: a body section (31); a fixed section (32) which is provided in the body section (31) on one end side; and an inner circumferential seal section (33) and a dust seal section (34) which are provided in the body section (31) on another end side, and the ball joint (100) is provided with a positioning member (40) which is mounted to the shaft section (11) in advance before the ball joint (100) is fitted to the knuckle (200) and which positions an end of the dust cover (30) on the other end side with respect to the shaft section (11) so that the inner circumferential seal section (33) is positioned at an opposite side of the spherical section (12) across the annular projection (11a).

Provided is a transport jig to be packed together with a double-row self-aligning roller bearing having an intermediate flange when the double-row self-aligning roller bearing is transported. The transport jig is formed in a ring shape having inner and outer diameters that allow the transport jig to be radially accommodated between an outer circumferential surface of an end portion of an inner ring and an inner circumferential surface of an end portion of an outer ring of the double-row self-aligning roller bearing, has a shape such that one side surface of the transport jig comes into contact with an end surface of each rolling element of the double-row self-aligning roller bearing and another side surface of the transport jig protrudes beyond end surfaces of the inner and outer rings, and is formed from a material softer than the rolling elements.

A device for supporting and installing a bearing assembly includes an inner ring having an inner ring axial face, an outer ring having an outer ring axial face and an outer diameter, and a plurality of rolling elements positioned between the inner ring and the outer ring. The device comprises a sleeve having an inner diameter sized and configured to receive and support the outer ring along the outer diameter, and a disc positioned within the sleeve. The disc includes a disc outer diameter sized and configured to permit sliding of the disc along the sleeve inner diameter in an axial direction of the sleeve, and a disc face surface sized and configured to engage the inner ring axial face, or the outer ring axial face, or both when the bearing assembly is received in the sleeve.
