An electrical submersible pumping system includes thrust bearings and radial bearings fabricated from a micro-grained polycrystalline diamond compact (“USPCD”) material that is ultra-strong; and where the USPCD is produced using a catalyst free process. In examples, all components of the bearings are formed from the ultra-strong USPCD material. Pads are in the bearings that have a contact surface, and the pads selectively tilt about a tilt member in response to variations in an opposing contact surface. The tilt members are attached to or otherwise associated with the pads, and are in contact with a resilient member that improves tilting response of the pads. The resilient members are encased in jackets that cover surfaces of the resilient members not in contact with the tilt members. The jackets are set in channels formed in structure of the bearings.

A self-aligning bearing support assembly for supporting a radial load rotary or linear bearing. The bearing support assembly has a main axis (A) and includes an outer sleeve and an inner sleeve at least partially received in the outer sleeve. The inner sleeve has an axially extending bore for supporting a rotary or linear bearing or for forming a bearing surface of a bearing. Three or more circumferentially separated chambers are formed between the inner sleeve and the outer sleeve. Each chamber is confined in all directions by walls of the assembly. A lump of a substantially incompressible material fills each of the at least three chambers with the chamber concerned substantially completely enclosing the lump.

To reduce the effect of a steering operation on feeling. A rack bush comprises: a bush body that is accommodated in a cylindrical housing, supports a load exerted on a rack bar while allowing the rack bar to move in the direction of an axial center O, and can be extended and retracted in a radial direction; and an elastic ring mounted on the bush body. The bush body has a mounting groove for mounting the elastic ring, the mounting groove being formed peripherally in an outer peripheral surface, and the mounting groove having a large-diameter part where the circumferential radius of a groove bottom is a first radius r1, and a small-diameter part where said radius is a second radius r2 that is less than the first radius r1. This configuration allows the formation of an elastic ring protruding part, in which the elastic ring protrudes greatly from the outer peripheral surface of the bush body, and an elastic ring embedded part, in which the elastic ring is embedded in the outer peripheral surface of the bush body.

A laminated elastomeric journal bearing has an outer sleeve having an inner surface, at least a portion of each end of the inner surface being a concave surface of revolution, and an inner sleeve having an outer surface, at least a portion of each end of the outer surface being a convex surface of revolution. Alternating layers of elastomer and metal are located between the sleeves, with adjacent surfaces of the layers and the sleeves being adhered to each other.

A positioning unit for technical applications in motor vehicles, in particular a locking system, a door positioner or a sliding door drive, having a housing, a drive arranged in the housing, a control element which can be acted upon by the drive, and a bearing location for the drive, in which the bearing location is formed at least partly of plastic, wherein the bearing is designed as a separate bearing location, and at least part of the drive is insertable into the bearing location.

A rubber bush with an inner part (2) which extends in an axial direction (x), an outer sleeve (3) which surrounds the inner part (2) at a spacing and comprises two half shells (4, 5) which are configured as identical parts, and a rubber body (6) which is arranged between the inner part (2) and the outer sleeve (3), wherein the half shells (3, 4) are connected to the inner part (2) by the rubber body (6) and, at their circumferential-side ends which face one another, have projections (7, 8) and depressions (9, 10), into which the projections (7, 8) are insertable.

A gas bearing for a compressor includes a bearing portion and a sealing portion mounted to a bearing housing of the compressor via one or more dampers, and the sealing portion being fixedly connected to the bearing portion, and a vent with an inlet in the bearing. The bearing portion has an inner radial surface for radially supporting a shaft of the compressor. The sealing portion has a sealing surface. The inlet of the vent disposed between the inner radial surface and the sealing surface. The sealing surface and a rotating surface form a path that extends along the sealing surface. The path extending from a pressurized volume of the compressor to the vent, and the pressurized volume containing a fluid.

A bearing structure (100) of the present disclosure includes: a rotating shaft (11); a dynamic bearing (12) including a foil (22) and a foil holder (21), the foil (22) being disposed around the rotating shaft (11) to constitute a bearing surface, the foil holder (21) holding the foil (22); a bearing support member (13) disposed around the dynamic bearing (12) to support the dynamic bearing (12); and at least one elastic body (14) disposed between the bearing support member (13) and the foil holder (21).

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 gas bearing for a compressor includes a bearing portion and a sealing portion mounted to a bearing housing of the compressor via one or more dampers, and the sealing portion being fixedly connected to the bearing portion, and a vent with an inlet in the bearing.
