The bearing unit including a radially outer ring provided with respective radially outer raceways, a radially inner ring provided with respective radially inner raceways, a plurality of rolling bodies positioned between the corresponding inner and outer raceways, a sensor for detecting the speed of rotation and the associated sensor holder. A cavity is formed in the radially outer ring of the bearing unit and a protuberance is formed on the outer mounting diameter of the sensor holder, the protuberance being able to be inserted inside the cavity to perform an anti-rotation retention function and ensure the mechanical orientation of the sensor holder.

Flanged inner ring of a rolling bearing forming part of a wheel hub unit of motor vehicles, having at its axially inner end a rolling edge configured to preload axially a radially inner ring after being plastically deformed by orbital forming. The rolling edge is provided with a conical surface of an axially inner portion of the rolling edge. A first parameter is defined as being the ratio between the conicity of the conical surface expressed in degrees and the thickness of the rolling edge expressed in millimeters and assumes values ranging between 0.03 mm.sup.−1 and 2 mm.sup.−1.

A bearing device (1) for a vehicle wheel provided with: an outer member (2); and an inner member comprising a hub wheel (3), and at least one inner wheel (4) press-fitted into the small-diameter ridge (3A) of the hub wheel (3); wherein a belt-shaped part (2F) that radially protrudes by a protrusion amount (P1) is formed over a prescribed width (W1) in the outer peripheral surface of the outer member (2) so that at least part of the belt-shaped part (2F) radially overlaps the outside rolling surface (2D) which is on the vehicle-wheel-attachment-flange-facing side of the outer member (2). The present invention addresses the problem of providing a bearing device for a vehicle wheel in which the amount of deformation in an opening of an outer member can be reduced and decreases in rolling fatigue service life can be prevented while keeping overall weight increase to a minimum.

A flip device includes a bracket including a first limit member, a positioning and connection assembly including a second limit member, and a rotation-shaft rocker arm rotatably connected to the bracket through the positioning and connection assembly. The first limit member and the second limit member are configured to mate with each other to enable the rotation-shaft rocker arm and the bracket to be fixed relative to each other at a preset angle.

A rolling bearing of the present invention includes an inner ring, an outer ring and a rolling element which are all made of a steel material, and (A) a surface of the rolling element is formed with an Ag coating film, and a raceway of at least one of the inner ring and the outer ring is formed with a Cr coating film or (B) a surface of the rolling element is formed with a Cr coating film, and a raceway of at least one of the inner ring and the outer ring is formed with a Cr coating film.

A wheel bearing assembly may include a wheel hub having a hub flange; one or more inner rings configured to be mounted to one side of the wheel hub; an outer ring provided radially outward of the one or more inner rings; a spacer coupled to a vehicle-body-side end portion of an inner ring disposed on a vehicle-body-side; and one or more rolling elements provided between the one or more inner rings and the outer ring. The one or more inner rings may be configured to be held on the wheel hub by plastically deforming a vehicle-body-side end portion of the wheel hub in a radially outward direction. A plurality of recesses for accommodating rotating elements of a constant velocity joint may be formed on an inner peripheral surface of the vehicle-body-side end portion of the wheel hub in a spaced-apart relationship with each other along a circumferential direction.

A flanged inner ring for wheel hub bearings is disclosed, wherein a tubular supporting body for the bearing is coaxial with an axis (X), and is provided with a flange, transverse to the axis (X), is provided with a plurality of threaded through holes distributed around the axis (X), and is axially delimited by an outer annular mounting surface and by an inner surface axially facing an outer ring of the bearing.

A sealing device located between an inner member and an outer member that rotate relative to each other, for sealing a gap between the inner member and the outer member, includes a first sealing member that is to be mounted on the outer member and a second sealing member that is to be mounted on the inner member. Multiple water-discharging protrusions are supported by at least one of the first sealing member and the second sealing member. The multiple water-discharging protrusions protrudes in a space located between an annular part of the first sealing member and a flange part of the second sealing member and are arranged in a circumferential direction. Each water-discharging protrusion includes an inclined side surface intersecting at an acute angle with a rotational direction in which at least one of the inner member and the outer member rotates.

An electric power steering system includes: a steered shaft, a housing containing the steered shaft therein in a movable manner; a ball screw nut engaged threadedly to the steered shaft via a plurality of balls and configured to move the steered shaft in an axial direction; a double row angular contact ball bearing configured to retain the ball screw nut and to support the retained ball screw nut rotatably relative to the housing; a wall portion placed at either side of the double row angular contact ball bearing in the axial direction of the steered shaft, the wall portion being formed integrally with the housing; and an elastic member provided between the wall portion and the outer ring portion and configured to retain the double row angular contact ball bearing to be elastically displaceable in the axial direction.
