The invention relates to a wheel end assembly for a vehicle, comprising a central wheel support member such as a spindle or a steering knuckle, and an outboard wheel end bearing arranged concentrically around the central wheel support member. The outboard wheel end bearing comprises roller elements accommodated between an inner race-forming part and an outer race-forming part surrounding the inner race-forming part. The inner race-forming part is configured to be supported by the central wheel support member. The central wheel support member comprises a first rotational lock portion. The inner race-forming part comprises a second rotational lock portion configured to engage with the first rotational lock portion to prevent the inner race-forming part from rotating relative to the central wheel support member. The invention also relates to a vehicle comprising such a wheel end assembly.

A flexible cartridge assembly can include a flexible shell that includes a flexible portion disposed between a compressor-side portion and a turbine-side portion, where the flexible portion includes a series of arc-shaped cutouts disposed axially along at least a portion of the flexible portion; a compressor-side bearing assembly; and a turbine-side bearing assembly.

An outer ring (26) for a bearing assembly includes an annular backing member (54) having a body, and an annular race member (50). The body has a first portion defining a radial inner surface (98) and a radial outer surface, and a second portion defining an axially-facing base surface (110) and a radially-facing end surface (118). The annular race member has a radial outer face (58) and a radial inner face, and a first axial end face and a second axial end face (70) that both extend between the radial outer face and the radial inner face. The annular backing member is in press-fit engagement with the annular race member such that the radial outer face of the annular race member engages the radial inner surface of the annular backing member and the second axial end face of the annular race member engages the axially-facing base surface of the annular backing member such that the members are unitized.

In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

A support ring assembly for a railway axle having a support ring configured to be inserted between a rolling bearing and a collar of the railway axle, the support ring having an annular seat, a surface of a radially inner side wall fitted with a radial clearance over the collar and an end wall that abuts against the collar, an annular insert fitted into the seat by means of an annular shield and having an elastomeric annular element having at least two annular protuberances that engage with the collar, the annular element configured to engage with the collar so as to occupy the radial clearance.

An intermediate shaft includes a first hollow shaft portion in which a plurality of grooves are formed in a longitudinal direction thereof, a second hollow shaft portion coupled at one end thereof to a first slip member, provided to be accommodated inside the first hollow shaft portion, and slipped into the first hollow shaft portion when a collision occurs, and a shaft portion to which a second slip member is coupled, provided to be accommodated inside the second hollow shaft portion, and slipped into the second hollow shaft portion when the collision occurs. A first press-in portion is formed on an inner circumference of the first hollow shaft portion to protrude therefrom, thereby pressing and supporting the first slip member.

A bearing device includes a first ring and a second ring mounted for relative rotation and an insulating sleeve mounted on the second ring. The insulating sleeve incudes a socket and an electrically insulating liner, the liner contacting the second ring. The socket includes an outer surface and an inner surface opposite the outer surface, and the outer surface and the inner surface delimit a radial thickness of the socket. The insulating liner is overmolded on the second ring of the bearing and on the outer surface and/or the inner surface of the socket. The socket and the insulating liner are shaped such that the insulating liner is prevented from moving circumferentially relative to the socket.

A method for performing uptower maintenance of a wind turbine in order to replace the main bearing on the turbine shaft is disclosed. Embodiments of this method to perform maintenance may include installing a rotor lock to resist rotation of the main shaft during maintenance, providing a lifting device in order to elevate the main shaft, removing the main bearing from its main bearing housing, and installing a replacement split main bearing. A crane may also be installed uptower to assist in the maintenance.

A combined insulator and conductor assembly is for a bearing disposable between a shaft and a housing and includes an annular insulator disposeable about the bearing outer ring. The insulator is configured to prevent electric current flow between the outer ring and the housing and includes one or more axial mounting tabs. An electrical conductor has an outer radial end, an inner radial end and at least one retainer, the at least one retainer being engageable with the at least one mounting tab to releasably couple the conductor with the insulator. Each retainer includes a radially-extending prong engageable with a separate tab. The conductor outer radial end or/and a portion of the conductor between the outer and inner ends is conductively engageable with the housing and the conductor inner radial end being conductively engageable with the shaft so as to provide a conductive path between the shaft and the housing.

A bearing arrangement for a turbomachine includes first and second roller element bearings. The first bearing and the second bearing are disposed on opposite axial ends of an intermediate sleeve of the rotating group. The first bearing has a first inner race with a first inner radial surface and a first outer radial surface. The first inner radial surface has a first interference fit with a shaft of the rotating group. The first outer radial surface has a second interference fit with the intermediate sleeve. The second bearing has a second inner race with a second inner radial surface and a second outer radial surface. The second inner race receives the shaft with a clearance fit. The second outer radial surface has a third interference fit with the intermediate sleeve. The second inner race is coaxially aligned with the first inner race and the shaft via coaxial alignment of the intermediate sleeve and the first inner race.
