A bushing utilizes a fabric reinforced thermoset composite sleeve incorporated within an outer shell in a construction enabling the sleeve to be press-fitted within the shell and held therein by a constriction in the shell bore which is embraced by the bearing liner. Following installation of the bearing sleeve, the sleeve bore may be reamed to provide a uniform inside diameter.

Semi-tubular portions of two partition members partitioning a bushing body into an outer rubber portion and an inner rubber portion are asymmetrically arranged with respect to a reference plane containing a central axis of the bushing body and parallel to two attachment surfaces of a bracket. In addition, each of the semi-tubular portions is configured to have a length equal to or larger than a diameter of a stabilizer bar, the length being from one end to the other end in a circumferential direction of the semi-tubular portion in a projection view obtained by projecting the semi-tubular portion to a horizontal surface in a vertical direction.

The invention discloses a bearing bush with a functionally graded bionic texture as well as a preparation method and a water lubricated bearing thereof. The bearing bush is characterized in that the surface of the bearing bush is provided with the bionic texture capable of realizing functional gradient, and the bionic texture comprises a radial ridge-shaped hydrophilic surface texture imitating acommon nepenthes lip and a crescent hydrophobic surface texture imitating a waxy region. According to the bearing bush, antifriction between the bearing bush and two sliding surfaces on a shaft is realized, and a lubricant is directionally conveyed from the end part to the middle part, so that the lubricating state of the middle area of an inner ring bearing bush is improved.

The present invention pertains to a bearing shell for a ball-and-socket joint, wherein the bearing shell has a core component consisting of a first material, which is completely enclosed by a jacket component consisting of a second material.

A manufacturing method of a water lubricated bearing taking hard rubber as a liner belongs to the field of a manufacturing method of a bearing. The problem that the existing manufacturing method of the rubber bearing is inapplicable for the water lubricated bearing taking the high-hardness rubber as the liner is solved. The method comprises the following steps of: mixing and milling the hard rubber by a double-roller mill, winding the mixed and milled hard rubber on a central spindle, arranging the mixed and milled hard rubber on a mold base, covering an upper cover of the mold on the mixed and milled hard rubber, arranging the mold on a vulcanizing machine, vulcanizing for 20-30min under the condition of 120 DEG C to 180 DEG C, opening the mold, de-molding, obtaining the water lubricated bearing lining blank product, performing machine finishing to the water lubricated bearing lining blank product, then arranging the product in a bearing sleeve, and obtaining the water lubricated bearing taking the hard rubber as the liner. Aiming at the defect that the hard rubber is hard to flow, a novel sleeve mold and the vulcanizing technique are used for preparing the water lubricated bearing; and the preparation method is simple, and high in efficiency, and is beneficial for mass production.

A method and a device is provided for producing a flat or arc-shaped sliding element with a very large radius of curvature. The sliding element has a sliding layer based on a fiber reinforced plastic with a plastic matrix and a reinforcing element containing at least one thread. The reinforcing element is deposited on a polygonal winding core by means of a guide with the addition of a synthetic resin forming the plastic matrix. The flat or arc-shaped segments formed between the edges are separated from the tubular, polygonal winding body thus formed after it has set.

A multi-layer seal and washer that provide a seal between a vane stem and a casing in a turbine engine are disclosed. The seal and washer are fabricated from materials such as Teflon fibers and glass fibers and are impregnated with a polyimide resin. The seal and washer are durable and have a low coefficient of friction.

A small-bored cylindrical bearing member which can enhance the maintainability for a lubricating oil therein. The member has blind grooves in a seamless cylindrical central body portion of the interior hollow cylindrical surface of the bearing member. A method of manufacturing the cylindrical bearing member having blind grooves with blocked-in end portions extending in the longitudinal direction of the cylindrical portion and spaced from the ends of the member. The grooves can be easily formed in the central body portion of the inner circumferential cylindrical surface of the central body portion with the blocked-in ends spaced from the opposite ends of the seamless bearing member. The seamless member is first formed with a tapered or flared portion at one open end which is later narrowed into a round cylindrical form. Before narrowing the tapered or flared portion, the blind grooves are formed by a groove punch pushed through the open end into the central body cylindrical portion. After narrowing, the blind grooves have blocked end portions spaced from the opposite ends of the bearing in the longitudinal direction.

A suspension coupling for use in a vehicle suspension system the suspension coupling including a knuckle and bushing assembly wherein the knuckle member is a cast aluminum piece having a passage for receiving a two-piece bushing having a formed, metal inner member and a molded, elastomeric outer member having extension members at each end. The bushing member is press-fit into the knuckle member and exhibits higher stiffness in the radial and axial directions and lower stiffness in the torsional and conical directions.

The invention provides an elastic metal-plastic bush and a manufacturing method thereof. The elastic metal-plastic bush comprises a bush base (10), a composite resin layer (20) and a plurality of connecting columns, wherein the composite resin layer (20) is fixed on a connecting surface of the bush base (10), each connecting column comprises a first end and a second end which are arranged oppositely, the second ends are fixedly connected with the connecting surface of the bush base (10), the height of the connecting columns is smaller than the thickness of the composite resin layer (20), and the bush base (10) and the composite resin layer (20) are fixed through the connecting columns.
