The invention relates to a multi-layer sliding bearing (1) comprising a sliding layer (3) having a surface for contacting a component which is to be mounted. Said sliding layer (3) is made from a tin-based alloy with tin as the main alloy element and the sliding layer (3) has on the surface, at least in sections, an oxidic subcoating (6) in which the proportion of tin oxide(s) is at least 50% in wt.

A corrosion-protecting layer system, e.g., for a bearing component used in a wind turbine, includes a base layer that contains polyurethane, zinc, and vinylphosphonic acid or silane. An intermediate layer is formed on the base layer and contains polyurethane and zinc. A top layer is formed on the intermediate layer and contains polyurethane and micaceous iron oxide. A sealing layer is formed on the top layer and contains polyurethane.

The invention relates to a plain bearing composite material, comprising a supporting layer (12) made of steel, a bearing metal layer (14) made of copper or a copper alloy, which is applied to the supporting layer (12), and a functional layer (16) made of aluminum or an aluminum alloy, which is applied to the bearing metal layer (14).

The invention relates to a method for producing a bi-material sliding bearing (1) whereby a metal sliding layer (3) of at least two different particle types is deposited under reduced pressure from the gas phase on a flat, metal substrate (8), and a first particle type forms a matrix with first grains and the second particle type forms grains embedded in the matrix of the metal sliding layer (3), and the metal sliding layer (3) is produced with a thickness (4) of more than 250 m and with a Vickers hardness below 100 HV(0.025), and the metal sliding layer (3) is made of a single layer in only one pass and with a maximum grain size of at most 1 m for at least 90% of the first grains forming the matrix and with a maximum grain size for at least 90% of the embedded grains, and a maximum particle size of at most 1.5 m for the remaining grains making up 100% of all grains.

The invention relates to a method for producing a rolling bearing cage for a rolling bearing comprising at least one row of rolling elements. In the method according to the invention, a ring or a ring element made of a metallic solid material is provided and shaped by a forming process and/or a cutting, material-removing process into an annular or segmented main body of the rolling bearing cage. The main body has openings for receiving a respective rolling element, the main body being heated to a temperature above a minimum coating temperature for thermal coating with a thermoplastic material powder, wherein the main body is then immersed in a fluidized bed containing the thermoplastic material powder, wherein thermoplastic material powder adheres to the main body, melts and forms a contiguous coating while the main body is present in the fluidized bed, and wherein, after the coating, the main body is removed from the fluidized bed. The invention further relates to an axial-radial rolling bearing with the described rolling bearing cage.

A plain bearing comprising a generally cylindrical sidewall having a first axial end and a second axial end; and a curved portion disposed at the first axial end, wherein the generally cylindrical sidewall has a thickness, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the generally cylindrical sidewall, and wherein n equals 2, 3, 4, or even 5.

A bearing element may include an overlay layer which forms a bearing surface against a steel journal or the like. The overlay layer may be formed from a bearing material comprising a polymer matrix of polyamide-imide polymer material, melamine cyanurate particulate, and metal oxide particulate. A method of forming the bearing element comprising the bearing material are also provided.

A rolling bearing 1 includes an inner ring 2 and an outer ring 3 that are raceway rings, and a plurality of balls 4 interposed between the inner ring and the outer ring. The outer ring 3 is fitted to a housing 10. The rolling bearing 1 includes a surface coating film 8 on an outer ring outer diametrical surface 3a that is a fitting surface with the housing 10. The surface coating film 8 contains: a binder containing two or more kinds of thermosetting resins having different average molecular weights; and a solid lubricant. The solid lubricant contains molybdenum disulfide, polytetrafluoroethylene resin, and graphite.

A bearing unit comprising rolling elements, housed in a radially inner mounting seat of a casing. The bearing unit includes a radially outer and stationary coated ring provided with a metal ring and a liner of elastomeric material integral with a radially outer surface of the metal ring, a radially inner ring, which is rotatable with respect to an axis of rotation (X), and a row of rolling elements interposed between the coated ring and the radially inner ring. The elastomeric material of the liner is a vulcanized thermoplastic material. The liner is co-molded onto the radially outer surface of the metal ring and may include a cylindrical body and at least two annular protuberances which fit inside corresponding anchoring grooves formed on the surface of the metal ring.

An example shaft, such as a crankshaft, has a coated wear sleeve disposed thereon. The coating on the wear sleeve provides tribological and/or mechanical benefits. The coating has a lower coefficient of kinetic friction than a conventional wear sleeve. The coating may further have a relatively high hardness. The coating may include a diamond like carbon (DLC) film or a metal-doped DLC (Me-DLC) film, such as tungsten (W)-doped DLC (W-DLC) film. The coating may be deposited on a bulk portion of the wear sleeve using physical vapor deposition (PVD) or similar processes. The coated wear sleeve is configured to engage and make contact with a static seal. The static seal includes elements that make contact with the coated wear sleeve while the shaft and coated wear sleeve rotate. The reduced friction, due to the coating, enhances the lifetime of the static seal.
