The bearing housing having a base portion defining a footprint, a shaft receiving collar, and a bearing race disposed between the shaft receiving collar and the bearing housing. The sensor bearing housing assembly having a pair of lengthwise sidewalls configured to extend upward from the base portion and an endwise sidewall configured to extend upward from the base portion. The pair of lengthwise sidewalls and the endwise sidewall being joined to form a sensor volume for receiving a sensor therein generally defined within a vertical volume bounded by the footprint of the base portion. The sensor bearing housing assembly having a cutout formed in at least one of the pair of lengthwise sidewalls and the pair of endwise sidewall to permit access to a fastener extending through a mounting hole formed in the base portion.

A sensor bearing assembly includes a bearing having an inner ring and an outer ring centered on an axis, an impulse ring secured to the outer ring of the bearing, and a sensor device for detecting rotational parameters of the impulse ring. The sensor device includes a sensor housing and at least one sensor element supported by the sensor housing and cooperating with the impulse ring. An annular spacer is configured to axially abut against a lateral face of the inner ring of the bearing and the sensor housing is secured to the spacer. An outer diameter of the sensor housing is less than or equal to an outer diameter of the outer ring.

A transmission assembly for vehicles, including a rolling bearing having a sealing device composed of a first annular screen coupled with a stationary outer ring of the bearing and a second annular screen coupled with a rotating inner ring of the bearing. Radially outer first and second L-shaped portions of the first and second screens project axially from the bearing and towards a constant velocity joint, the first L-shaped portion having a first and a second annular lip which form with the second L-shaped portion a radial sequence of labyrinth seals. A third annular sealing lip may be arranged radially downstream of the sequence of labyrinth seals and cooperates in sliding contact with the second screen. An encoder may be mounted on the second L-shaped portion and may have an annular overhang which forms with the first lip a first labyrinth seal.

A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

An encoder includes a rotatable encoder disc. A clamp is fixed to the encoder disc to rotate therewith. The clamp includes an arcuately extending body presenting a radially inner face and arcuately spaced apart ends defining a gap therebetween. The inner face extends along a clamping path and engages a rotating component to secure the clamp to the rotating component to rotate therewith. The clamp includes an adjustment mechanism for modifying an arcuate extent of the gap by shifting the ends relative to one another and, in turn, modifying the clamping path. The body defines a radially extending cutout facilitating bending of the body in association with expansion or contraction of the gap and modification of the clamping path. The clamp includes a raised boss extending from a front face thereof. The boss presents a contact face spaced axially from the front face and fixedly engaging the encoder disc.

A wheel bearing device (1) including: an outer member (2) on the inner periphery of which an outer-side rolling surface (2c/2d) is formed; an inner member (3) on the outer periphery of which an inner-side rolling surface (3c/3d) is formed; and a plurality of rolling bodies (41) interposed between the rolling surfaces (2c/2d/3c/3d) of the outer member (2) and the inner member (3). The wheel bearing device having a spline hole (3b) formed in a through hole (3h) of the inner member (3). The spline hole includes a guide groove (3G) formed on an inner circumferential surface thereof. A guide plate (8G) of a finishing broach (8) passes through the guide groove in the inner periphery of the spline hole (3b).

An arrangement for monitoring a centrifugal pump is provided. receiving the residual axial thrust of a centrifugal pump. The arrangement includes a load-relieving device configured to receive the residual axial thrust developed during pump operation, an axial bearing, and a sensor ring is associated with the axial bearing. The ring (10) is divided into segments having sensors at the segment dividing regions.

An encoder for a wheel bearing includes a carrier plate ring and a magnetic encoding ring. The carrier plate ring has a radially running first leg, and an axially running second leg arranged on an outer ring or on an inner ring of the wheel bearing. The carrier plate ring has, on the radially running first leg, cut-outs distributed over its circumference. The first leg has a fold for forming a folded portion, and the folded portion at least partly covers the cut-outs. The carrier plate ring is at least partly surrounded by the magnetic encoding ring. The encoding ring has unipolar magnetization and at least partly comes into contact in the cut-outs.
