A rolling bearing having an inner raceway and an outer raceway and a plurality of rolling elements arranged therebetween. The rolling bearing is media-lubricated or oil-free lubricated. The lubricant forms an elasto-hydrodynamic lubricant film between the rolling elements and the raceways. At first use of the rolling bearing, at least one surface of the rolling bearing is coated with a protective fluid, preferably an oil-based preservative fluid. Also, a refrigerant compressor having such a rolling bearing.

The present invention is directed at products and methods related to the manufacture of a bearing with a bearing liner and the bearing liner on its own. The bearing liner within the bearing includes a fabric with a bonding side polymerized resin composition dispensed on one side and a sliding side polymerized resin composition disposed on a second side that contains dispersed lubricant. The liner preparation also offers the ability for the liner to conform to a selected bearing surface.

A connection element providing a first ring and a second ring, the two rings rotating relative to one another about a central axis, the first ring having a contact portion with a contact surface interacting with the second ring for the relative rotation, and a fastening portion configured to be rigidly secured to a support. The contact portion is made of a first material and the fastening portion is made of a second material, different to the first material, the first material having a hardness strictly greater than that of the second material, and the second material having a structural fatigue strength strictly greater than that of the first material.

A solar tracker bearing apparatus mountable to an upright support post for rotatably supporting a torque tube beam of a solar tracker assembly and including: a rotatable bearing assembly supported for rotation about an axis of rotation by a stationary saddle assembly. The rotatable bearing assembly includes a central portion and first and second spaced apart arcuate peripheral portions, the central portion defining a beam slot, the first arcuate peripheral portion including a first arcuate rim bearing and the second arcuate peripheral portion including a second arcuate rim bearing, and the first and second rim bearings being spaced apart in a direction parallel to the axis of rotation of the rotatable bearing assembly. The stationary saddle assembly includes a first arcuate bearing race slidably supporting the first arcuate rim bearing and a spaced apart second arcuate bearing race slidably supporting the second arcuate rim bearing.

A shaft assembly includes a composite tube and an impact shield. The composite tube has a longitudinal centerline axis and the impact shield may be disposed around the composite tube and may extend along a length of the composite tube. A gap may be defined between the composite tube and the impact shield. Generally, shaft assembly is configured to inhibit impact damage to the composite tube and/or facilitate visual detection of damage from impacts. The shaft assembly may further include a shock absorbing sleeve disposed in the gap between the composite tube and the impact shield.

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 system or a kit of multiple composite driveshaft assemblies for vehicles is provided, with the with the different composite driveshaft assemblies having different performance characteristics. The different performance characteristics of the composite driveshaft assemblies may be achieved by varying, for example, filament material(s), filament winding depth(s), and filament wind angle(s).

A link includes an outer composite portion substantially encircling at least two bearing pockets and a central substantially incompressible portion disposed between the at least two bearing pockets.

A composite vehicle driveshaft assembly includes a composite tube and a yoke bonded to one of the ends of the tube. The yoke has an inner sleeve that is concentrically received in the end of the tube. The sleeve has an outer peripheral surface that faces the inner peripheral surface of the tube with a cavity formed therebetween. An adhesive injection passage is formed in the yoke and extends at an acute angle from an inlet that is formed in an axial surface of the yoke to an outlet that is formed in the outer peripheral surface of the sleeve and that opens into the cavity. Also disclosed is a method of bonding a yoke of such a driveshaft assembly to a composite tube.

A rolling-element bearing assembly includes a first bearing ring and a second bearing ring that define a bearing interior between them, a plurality of rolling elements disposed in the bearing interior to allow a relative rotation of first and second bearing rings, and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier that is connected to the first bearing ring such that they rotate together and a seal element that is connected to the seal carrier such that they rotate together, and the seal carrier comprises a fiber-reinforced plastic.
