A bearing component including a substrate; a sliding layer overlying the substrate; and a metal mesh comprising filaments embedded in the sliding layer, the metal mesh having a woven structure such that the filaments overlap each other at intersections, where a plurality of intersections include a first filament overlying a second filament, the first filament being mechanically so as to interlock with the second filament.

Embodiments of the invention are directed to compact bearing assemblies configured to operate in small spaces and/or in harsh environments, bearing apparatuses including such bearing assemblies, and method of operating such bearing assemblies and apparatuses. For instance, one or more compact bearing assemblies may at least partially rotatably secure a shaft of a power generation unit to a housing thereof. Also, a first compact bearing assembly may connect or couple to the shaft and may rotatably engage a second compact bearing assembly, which may be connected or otherwise secured to the housing.

A journal bearing is provided that supports a rotating shaft to be rotatable around a central axis and includes: a bearing main body that has a sliding contact surface that is in sliding contact with the rotating shaft, an outer circumferential surface that is directed outward in the radial direction to face a side opposite to the sliding contact surface, a recess that is recessed from an outer circumferential surface of the bearing main body inward in the radial direction, and a groove that continuously extends from the recess; a sensor main body that is housed in the recess; and a sensor wiring whose one end is connected to the sensor main body and in which a part thereof in a length direction is housed in the groove.

Sealing device for a wheel-hub unit provided with a rolling bearing and having a central axis and being provided with a screen joined together with an outer ring of the bearing to sealingly isolate the bearing and having a cylindrical mounting wall coaxial with the central axis and engaged with a collar of an outer ring of the bearing, and an annular reading wall, arranged transversely with respect to the axis, connected to the cylindrical wall and facing a phonic wheel mounted inside the bearing; the annular reading wall having a thickness variable radially depending on an angle of oscillation of the phonic wheel between an undeformed position. An annular front surface of the phonic wheel is equidistant from a plane perpendicular to the axis, and a possible deflected position, in which the annular front surface of the phonic wheel is arranged equidistant from an annular reading wall.

A sliding element for an engine may include a polymer-based overlay layer disposed on a metallic substrate. The polymer-based overlay layer may include a polymer-based matrix and a metal particulate. The metal particulate may be a surface treated metal particulate.

A coated bearing component comprising a metallic part and a coating deposited on the metallic part. The coating is a multi-layer coating having a sensor active layer made of a material having electrostrictive properties. The sensor active layer is directly coated on the metallic part. The bearing component can be integrated into a bearing.

A sliding component includes a pair of sliding parts each having an annular sliding face to relatively slide on each other. At least one of the sliding faces has a plurality of dimples disposed thereon. The dimples have substantially the same opening diameter, and are provided independently of each other. The ratio between the depth h and the diameter D of the dimples is set in a range of 1/500 to 1/10. The dimples are arranged randomly such that the area ratio of the dimples within a 120 unit angle in a circumferential direction of a sliding face is in a range of 8% to 50%.

A laminate includes a metal substrate and a sliding layer overlying the metal substrate. The sliding layer can include a polymer fabric. The polymer fabric can include first polymer P1. The sliding layer can further included a melt-processable matrix polymer. The melt-processable matrix polymer can include a second polymer P2. In embodiments, either P1 or P2 is a fluoropolymer. The sliding layer can further include a filler. In embodiments, the total amount of fluoropolymer and filler in the sliding layer is at least 30 vol %.

A method of forming a bearing ring having improved hardness is disclosed herein. The method generally includes a duplex hardening process in which the bearing ring is first subjected to a heat treatment. After the heat treatment process, the bearing ring undergoes a nitriding treatment in predetermined portions, including at least a raceway and a cage pilot surface.

Anti-friction composite material having: (A) polyimide substrate and (B) a coating layer containing a binder resin and a solid lubricant.
