A water lubricated composite thrust bearing of a nuclear main pump has a stainless steel base and an engineering plastic layer. The stainless steel base is provided with a concave-convex surface connected to the engineering plastic layer. The concave-convex surface and the engineering plastic layer are compositely molded by means of thermoplastic compound molding. A ratio of the area of the concave-convex surface to the area of an orthographic projection of the concave-convex surface on the stainless steel base ranges from 1.2 to 2. By means of the concave-convex surface and a specific bonding property obtained after fusion of a rough face and the engineering plastic layer, the concave-convex surface is bonded with the engineering plastic layer, thereby forming a reliable composite thrust bearing that is physically connected onto a whole.

A bearing for an internal combustion engine may include a steel support layer. A coating layer containing a Cu alloy may be laid over the steel support layer. A Ni-based anti-diffusion barrier layer may be laid over the coating layer, and an anti-friction layer containing a matrix of SnZn and Zn precipitates may be laid over the anti-diffusion barrier layer.

A connecting rod for connecting between a crankshaft and a piston, includes a small end with a cylindrical hole adapted to for receiving a piston pin, a big end having a crank pin bore adapted for receiving a crank pin of a crankshaft and a stem portion extends between the small end and big end. The stem portion can have an I-beam cross-section with a pair of legs and a web extending between the pair of legs. The web includes oppositely facing surfaces defining a thickness that is less than a thickness of the pair of legs. The web includes at least one grooved/recessed portion that is recessed relative to the oppositely facing surfaces of the web.

This ball joint is provided with: a ball stud having a stud part one end of which is coupled to a stabilizer device or a suspension device, and the other end of which is integrally joined to a ball part; a housing made of a metal material having a space, one end of which is open and which swingably and turnably supports the ball part of the ball stud; and a ball seat interposed between the housing and the ball part. A swaged section for swaging the ball seat is a lump having a mountain-shaped cross-section into which an opening rim part thinner than a trunk section of the housing is deformed by a compressive load.

To provide a rolling bearing having excellent rust prevention capability and capable of being used for a long period of time in a highly corrosion environment. A rolling bearing 1 utilized for a power generator which generates power from natural energy or for generator equipment has one or more bearing members which form the bearing having a rust prevention film formed in a predetermined region of a surface of a base material. The rust prevention film is formed by a porous film with a sacrificial anode action against the base material in the whole of the predetermined region. The porous film in a part or the whole of the predetermined region is subjected to sealing treatment which impregnates the porous film with a sealing treatment agent from a surface of the porous film. A surface of a sealing treatment body obtained from the porous film subjected to the sealing treatment is subjected to first coating treatment which coats the surface of the sealing treatment body with epoxy resin coating. A coated surface formed by the first coating treatment is subjected to a second coating treatment which coats the coated surface with urethane resin coating. The sealing treatment agent is formed by diluting the epoxy resin coating at a dilution rate of between 15 and 25%.

An outer casing for a control cable 10 has an inner tube 12, which includes a crystalline resin, and an outer tube 14, which includes an outer resin layer 16 covering the outer periphery of the inner tube and, in the outer resin layer, includes plural metal wires 18 buried in parallel with the axial direction of the inner tube and at equal intervals in the circumferential direction of the inner tube.

A sliding element with one substrate and at least one layer of a sliding layer material applied to the substrate is described. The sliding layer material can consist of a sliding coating with at least one cross-linkable bonding agent or at least one high-melting thermoplastic material or which consists of a material with a matrix of at least one high-melting thermoplastic material or at least one duroplastic material. This sliding layer material contains Fe.sub.2O.sub.3 with a preferred proportion 0.1 to 15% by volume.

An outer ring (2) is provided with a stationary ring-side flange (2a) along a circumferential direction. The stationary ring-side flange (2a) is provided with a plurality of mounting holes (2b) which is arranged at unequal intervals and which is used to fasten the outer ring (2) to a knuckle (N) through knuckle bolts (Bt). The stationary ring-side flange (2a) includes first flange part (30) located in a region in which a distance between adjacent mounting holes (2b) is larger and second flange part (40) located in a region in which a distance between adjacent mounting holes (2b) is smaller. A radial thickness of the first flange part (30) is a greater than a radial thickness of the second flange part (40).

A slide bearing can include a metal support, a primer layer, an adhesive layer applied directly thereto, and a sliding layer applied to the adhesive layer. The primer layer can include an oligomeric condensate of at least one silanol selected from the group having the formula:

##STR00001## wherein x is 1 or 2, y is 0 or 1.

The moieties R.sup.1 and R.sup.2 can be the same or different. The moieties R.sup.1 and R.sup.2 can be selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, and a functionalized alkyl group R(CH.sub.2).sub.z, wherein z is at least 1. Slide bearings comprising a primer system based on silanol oligomeric condensates show improved peel strength than their analogous slide bearings lacking the primer system.
