A method of manufacturing a hub unit bearing (1) includes the step of applying an axial load to a shaft end of a hub body (21) so that a staking portion (26) for inner races (22a, 22b) is formed in the hub body (21). The load is adjusted based on at least one of first information acquired before applying the load and second information acquired while applying the load.

The invention relates to a wastegate actuator mechanism comprising an elongated link plate and a pin which are rotatable relative to each other. The wastegate actuator mechanism further comprises a sliding assembly including a bushing fixedly connected to the link plate and a sleeve fixedly connected to the pin. Assembly of the wastegate actuator mechanism involves pressing the bushing into the eye of the link plate and allowing material of the link plate to deform and to be received in recessed portions of the bushing in the process and/or arranging the sleeve on the pin and allowing material of the pin to deform and to be received in recessed portions of the sleeve in a process of forming an end section of enlarged diameter on the pin.

A preload inspection method for a bearing device for a vehicle wheel comprises: a first bearing preload value calculation step for calculating a first bearing preload value; a first rotating torque measurement step for measuring a first rotating torque; a caulking step for swaging the small-diameter stepped part to the inner ring; a second bearing preload value calculation step for calculating a second bearing preload value; a second rotational torque measurement step for measuring a second rotational torque; a third bearing preload value calculation step for calculating a third bearing preload value by adding, to the first bearing preload value, a preload change amount based on a differential torque between the first rotating torque and the second rotating torque; and a determination step for determining the suitability of the preload from the second bearing preload value and the third bearing preload value.

The present invention may provide a motor comprising: a rotation shaft; a rotor including a coupling hole in which the rotation shaft is disposed; a stator disposed outside the rotor; and a housing for receiving the rotor and the stator, wherein the housing comprises: a body; a bracket disposed on one side of the body and including a hole and a bearing pocket part disposed along the circumferential direction with respect to the center of the hole; and a bearing disposed in the bearing pocket part, wherein the inner surface of the bearing pocket part includes a first surface, a second surface, and a third surface, and wherein the first surface comes in contact with the outer circumferential surface of the bearing, the second surface comes in contact with the upper surface of the bearing, and the third surface is disposed between the first surface and the second surface in the height direction of the bracket while being spaced apart from the outer circumferential surface of the bearing.

A wheel bearing includes a first seal member disposed between an outer ring and a first outer peripheral surface of a first cylindrical portion of an inner ring and configured to seal between the outer ring and the inner ring; and a second seal member press-fitted to a second cylindrical portion of the inner ring. The second seal member includes a slinger comprising an outer axial end portion spaced apart from the first seal member and a first end surface of the inner ring; a first seal lip coupled to the outer axial end portion of the slinger and comprising a first seal portion in contact with a portion of the first seal member and a second seal portion in contact with a portion of the first cylindrical portion; and a second seal lip coupled to the slinger so as to be spaced apart from the first seal lip.

A plurality of press rolls (33) each having an inclined roll central axis (β) are used. Each of press rolls (33) and a hub ring (22z) are relatively rotated while pressing a roll processing surface portion (34) of each of the press rolls (33) against a plurality of locations of a tubular portion (25) of the hub ring (22z) in a circumferential direction to plastically deform the tubular portion (25).

A bushing collar assembly on a vehicle includes a subframe formed of a first material and a bushing collar formed of a second material. The subframe has an engagement face. The bushing collar has a sleeve shaped main body defining axial end faces. At least one of the axial end faces has a plurality of spaced apart nubs disposed thereon that are configured to deform and fully embed into the engagement face of the subframe upon application of a predetermined compressive force.

A ball joint assembly, a ring for use in a ball joint assembly, a seat for use in a ball joint assembly, and a method of assembly a ball joint are provided. The ball joint assembly includes a ball stud with a spherical portion and a tapered portion, wherein the spherical portion is positioned in a seat. The ring is formed as an annulus shape and includes a ring projection positioned at an outer surface of the ring, the ring for mounting between the seat and a housing of the ball joint assembly to press-fit high load to the seat. The ball joint assembly includes a seat for attaching to the ball stud at the spherical portion and to support the ring with high stress. The seat includes a seat projection comprising a portion of the seat extending beyond an outer surface of the seat towards the housing.

A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (α) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).
