The ball socket assembly includes a housing with an inner bore, and a bearing is received in the inner bore. The bearing is made as a monolithic piece of a plastic material and has a curved bearing surface which surrounds a ball cavity. The ball socket assembly also includes a ball stud with a ball portion and a shank portion. The ball portion is received in the ball cavity of the bearing and has an equator. The curved bearing surface of the bearing is in slidable contact with the ball portion on opposite axial sides of the equator. The plastic material of the bearing comprises 8-12 mass percent polytetrafluoroethylene, 2-6 mass percent carbon fibers, and the remainder acetal.

A suspension arm includes a ball stud including a spherical ball; a bearing in which the ball is accommodated; a housing having an inner peripheral portion, an outer peripheral portion, and a lower end portion that connects a lower end of the inner peripheral portion and a lower end of the outer peripheral portion, and configured to accommodate the ball and the bearing in a state in which the ball and the bearing are spaced apart from the inner peripheral portion; an arm body coupled to a portion of the outer peripheral portion of the housing; and an insert molding part formed on an outer peripheral portion of the bearing, the inner peripheral portion of the housing, and the lower end portion of the housing to couple the bearing with the housing. A convex-concave portion is formed on the inner peripheral portion of the housing along a circumferential direction.

A plain bearing for a steering spindle of a steering column for a motor vehicle. The bearing includes an inner ring with an axially continuous bearing opening for slidably receiving the steering spindle. A prestressing element is configured to exert a prestressing force on the inner ring to clamp the inner ring on the steering spindle and thereby to assign a defined, uniform braking torque.

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 resin sliding bearing includes: a bearing surface for slidingly bearing a shaft; and a hollow that communicates with the bearing surface through to a different surface of the bearing.

A bearing material including a substrate, and a sliding layer overlying the substrate, where the sliding layer includes fillers including wollastonite in a wt % range between 10 and 30%, barium sulfate in a wt % range between 5 and 15%, and pigment in a wt % range between 0.1 and 5%.

A link arm member of the present invention is used in a vehicle for connecting a suspension and a stabilizer, and includes: a support bar that is sealed by plastically deforming a hollow metal pipe at both ends thereof; and a housing part made of resin that is arranged at each end of the support bar and has a receiving hole for receiving a ball part of a ball stud to which the suspension or the stabilizer is fixed, wherein the housing part is formed by insert molding with the support bar.
