A bearing including a sidewall including a substrate and a low friction material extending along at least one of a radially inner surface or a radially outer surface of the sidewall, the sidewall further including: a body defining a bore about a central axis; and a flange contiguous with and extending from an axial end of the body, where the flange includes a folded over outermost peripheral edge, where the substrate has a reduced thickness at the outermost peripheral edge, the flange being configured such that the substrate is not exposed along the outermost peripheral edge.

An assembly has a radial ball bearing including a bearing inner ring, and a rotatable shaft with a shaft end region with a bearing seat. The bearing seat has a shoulder on one side, on which the bearing inner ring of the radial ball bearing is seated for supporting the shaft. The bearing seat is shortened in the longitudinal direction relative to the radial ball bearing, and extends toward a height of the radial ball bearing. The bearing seat terminates at a distance (L) from an orthogonal projection from the proximalmost points of a distalmost row of balls onto the bearing seat surface such that L=k*D, wherein k is in a range between 0.7 and 0.5.

A ball socket assembly, bearing therefor, and method of construction thereof are provided. The ball socket assembly includes a housing with an inner bore extending between a closed first end region and an open second end region. A fiber-reinforced bearing is disposed in the inner bore. The bearing has a lower portion presenting a lower bearing surface having a first radius of curvature and an upper portion presenting an upper bearing surface having a second radius of curvature that is greater than the first radius of curvature. The lower bearing surface and the upper bearing surface surround a ball cavity in which a spherical ball portion of a ball stud is disposed. The housing second end region is plastically deformed radially inwardly to impart a bias on the bearing upper portion that causes the second radius of curvature to be biased substantially equal to the first radius of curvature.

A method for acquiring a contact angle of an angular contact ball bearing includes: a first detection step of detecting a number of rotation of a first bearing ring of an angular contact ball bearing; a second detection step of externally detecting deformation of a second bearing ring associated with orbital rotation of a ball of the angular contact ball bearing; and a calculation step of obtaining a contact angle α of the ball using a detection result of the first detection step, a detection result of the second detection step, and specification data pertaining to the ball.

A turbocharger and a method of manufacturing a floating bush with which noise can be reduced, and the rotation speed can be increased. In a turbocharger in which a rotating shaft having a circular cross-section and connecting a turbine rotor and a compressor rotor is supported in a freely rotatable manner, at two axially separated positions via floating bushes, by an inner circumferential surface disposed so as to surround the rotating shaft in a bearing housing, an inner circumferential surface of each of the floating bushes has a non-circular shape in which the curvature of the cross-sectional shape varies in the circumferential direction.

Provided is a method of manufacturing a wheel bearing apparatus including an outer ring, a rolling element, a hub spindle, and an inner ring member. The hub spindle is disposed inward of the outer ring in a radial direction via the rolling element. The inner ring member fitted on the hub spindle and is secured by a clinched portion. The clinched portion is formed by clinching a spindle end portion of the hub spindle outward in the radial direction. The method includes: plating a predetermined area including the spindle end portion of the hub spindle; removing a plating of the spindle end portion of the predetermined area; and clinching the spindle end portion to form the clinched portion after removing the plating.

A thrust foil bearing includes a base plate including an insertion hole through which a rotating shaft is inserted and a support surface disposed around the insertion hole on one side of the insertion hole in an axial direction, and a back foil disposed on the support surface, in which the support surface has a plurality of inclined surfaces of which inclination angles inclined toward the other side of the base plate in the axial direction become shallower in order toward an outside of the insertion hole in a radial direction, and the back foil is divided into a plurality of divided regions in the radial direction by a slit, and the plurality of divided regions are supported by the plurality of inclined surfaces.

A device for lightening the weight of vehicle components includes a tooling provided with a seat wherein the component is formed and a plurality of moveable bodies, which are moveable between an initial position and a final position, such that in the final position one end of each moveable body penetrates the seat of the tooling to form a cavity to lighten the weight of a component of the vehicle, wherein at least one of the moveable bodies can move laterally. Such device allows lightening the weight in a more simple and productive way than in currently known systems. This is achieved because the moveable bodies do not interfere with each other during the movement thereof, such that the lightening process can be done in a single blow during a forging procedure.
