A rolling bearing includes: an inner ring; an outer ring; and a plurality of rolling elements provided between the inner ring and the outer ring, wherein: one of the inner ring and the outer ring is a rotating ring; the other one of the inner ring and the outer ring is a firm ring; the firm ring is attached to a prescribed member; and a black oxide film having a mesh-shaped crack is formed on at least one surface of a fitting surface of the firm ring and a side face of the firm ring, the fitting surface facing the prescribed member in a radial direction of the rolling bearing, the side face making contact with the prescribed member in an axial direction of the rolling bearing.

An apparatus mounts a plain bearing shell of a plain bearing in a bearing seat of a component. The apparatus has an attachment region for releasably attaching the apparatus to the component. The apparatus has a supporting region for supporting the plain bearing shell during an insertion of the plain bearing shell into the bearing seat of the component. During the insertion into the bearing seat, the plain bearing shell can slide along on the supporting region, with the result that the plain bearing shell does not come into contact with an outer edge of the bearing seat.

A parking cable has a plurality of plastic split type liners, which reduces frictional resistance between the inner cable and a conduit among the components of the parking cable. The plurality of split type liners is press-fitted and disposed to a desired position in an inner diameter of the conduit. The plastic split type liners may serve as a guide that ensures force for smoothly moving the inner cable and also improve in-line assembly properties. A method of manufacturing the parking cable includes press fitting the plurality of split type liners between the inner cable and the conduit.

A wheel bearing unit includes a first inner ring having an axial end side, a second inner ring having an axial end side contacting the axial end side of the first inner ring at a joint, and a seal unit that seals the joint between the first inner ring and the second inner ring. The seal unit includes at least one seal element and at least one further component that exerts pressure on the at least one seal element, and the at least one further component is at least partially comprised of sheet metal.

The invention provides a fixed rolling element bearing assembly comprising: a housing; an inner race for attaching to a rotating shaft; a cage and rolling element assembly positioned around the inner race; first and second positional locators for positioning the cage and rolling element assembly between inner edges thereof; a thrustwasher adjacent an outer edge of either of the first or second positional locator and fixably connected to the housing.

A retaining element for retaining a component within a receiving part, the retaining element including: a neck portion to be received within a notch formed in the receiving part; a first head portion coupled to the neck portion end and defining a first shoulder; a second head portion coupled to another neck portion end and defining a second shoulder, wherein the first and second shoulders oppose one another and are to abut first and second surfaces of the receiving part so as to engage the retaining element with the receiving part; wherein the first and/or second head portions include a retaining tab having a retaining surface, wherein the retaining tab has a receiving position for receiving the component and retaining position for retaining the component; wherein, in the retaining position, the retaining tab extends beyond the neck portion so the retaining surface abuts the component surface to retain the component.

A clamping ring (6) includes: a ring main body (10) including a cut (13) formed in a part in a circumferential direction and a pair of circumferential-direction end portions (14a and 14b) opposed to each other across the cut (13); and bolt holes (11a and 11b) passing through the pair of circumferential-direction end portions (14a and 14b). The clamping ring (6) further includes a misalignment preventing part (16) configured to prevent misalignment of a center of gravity (CG) of the ring main body (10) from a center line (C1) of an inner peripheral surface (10a) of the ring main body (10).

An apparatus (10) for preloading a bearing assembly (14) on a shaft (12) includes a first annular threaded member (56) positioned about the shaft (12) and a second annular threaded member (68) positioned about the shaft (12). The first and second threaded members (56,68) have intermeshing threads such that rotation of the second threaded member (68) causes axial translation of the first threaded member (56) to apply a first axial force to the bearing assembly (14) to preload the bearing assembly (14). An actuator is operable to rotate the second threaded member (68) relative to the first threaded member (56) to apply the first axial force to the bearing assembly (14).

Disclosed is a secondary clamping device for a wheel. Two bearings and a spacing ring are closed in a base by a bearing end cover, a shaft sleeve is mounted on the bearings, a linear bearing and a gland are fixed on the shaft sleeve, a positioning pin is fixed at the top of the floating shaft, two ends of the spring A are respectively connected with the positioning pin and the linear bearing, and the positioning pin can move up and down under the action of the spring A. A pull rod is fixed on the gland, the outer wall of the floating column is connected with the inner hole of the shaft sleeve, two ends of the spring B are respectively connected with the gland and the floating column.

A bearing unit (10) has a radially outer ring (31), a radially inner ring (33), an eccentric locking collar (40), a row of rolling bodies (32), and a sealing device (50). The sealing device (50) is arranged on the same side as the locking collar (40) and is interposed between the radially inner ring (33), the radially outer ring (31) and the locking collar (40). The sealing device (50) includes a metal shield (55) stably connected to the radially outer ring (31), and an elastomeric component (60) co-molded on the shield (55) in a radially inward direction. The elastomeric component (60) has a plurality of lips, of which at least one lip (64, 65) is in contact with the locking collar (40).
