A bearing device for a beauty and health roller which presents no risk of bathwater or bathtub contamination, is hygienic, is less heavy than conventional ball bearings, is devoid of roller rattle, and exhibits a small rotational resistance of the rollers. The bearing device for a beauty and health roller is used in a beauty and health roller having a grippable body and a roller arranged at the end portion of the body, and rotatably supports the roller on a supporting shaft provided to the end portion of the body. The bearing device comprises a radial bearing 5 into which the supporting shaft is fitted and which rotatably supports the roller on the supporting shaft 2a.

A sliding member includes a substrate, a first coating film layer which is provided on the substrate, and a second coating film layer which is provided on the first coating film layer. The first coating film layer including a coating film including a composition for a sliding member. The composition for a sliding member contains a binder resin, a solid lubricant, and at least one type of resin beads selected from the group consisting of amino resin beads and urethane resin beads. The second coating film layer includes the binder resin and the solid lubricant.

A self-lubricating SLZ-type tow dolly assembly provides a self-lubricating bearing sleeve operable in an SLZ-type tow dolly. This serves to negate the need for grease fittings and manually greasing of the spindle bushing. The self-lubricating bearing sleeve press fit into a spindle bushing disposed in a spindle assembly to lubricate the spindle bolt. This facilitates rotational motion against the spindle bolt. In one embodiment, the self-lubricating bearing sleeve is a self-lubricating Igus M250 bearing sleeve that press fits into dolly pivot bushings. Rotational and linear motion creates pressure that discharges incremental amounts of the lubricant. Thus, self-lubricating bearing sleeve serves as a self-lubricating, pivot-point bearing sleeve. The self-lubricating bearing sleeve may be a plastic component with a lubricant integral therein. This allows for self-lubricating of bushing and spindle components during rotation of spindle assembly. In alternative embodiments, a trip assembly and a spindle assembly operate in the self-lubricating bearing sleeve.

The present disclosure relates to a low friction bearing liner for a solenoid may include a low friction layer. The low friction layer may include a first fluoropolymer matrix component and a first thermoplastic filler component distributed throughout the first fluoropolymer matrix component. The content of the first fluoropolymer matrix component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer. The content of the first thermoplastic filler component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer.

A bearing system includes a first bearing, the first bearing being annular in shape and defining a ring aperture, the first bearing including a first surface and a second surface, a second bearing being substantially the same in construction to the first bearing, a first surface of the second bearing contacting a second surface of the first bearing, wherein each of the bearings is constructed of nylon MDS.

A powder metallurgically produced, wear-resistant, and highly thermally conductive copper-based sintered alloy as matrix is disclosed. The sintered alloy includes a powder mixture of a copper-base powder, of a hard phase with a total share of 8 to 40% by weight, of a solid lubricant with a total share of 0.4 to 3.8% by weight, of a pressing additive with a total share of 0.3 to 1.5% by weight, and production-related impurities. The powder mixture includes at least 55% by weight of the copper-base powder.

A half thrust bearing for a crankshaft of an internal combustion engine is formed of a back metal layer and a bearing alloy layer to have a slide surface and two thrust reliefs. Each thrust relieve includes a first region, where the back metal layer is exposed, on a circumferential end surface side, and a second region, where the bearing alloy layer is exposed, on the slide surface side while the slide surface includes two third regions adjacent to the second region, and a fourth region between the two third regions. A circumferential end region consists of the first, second and third regions. In the second region and the third regions, the bearing alloy layer includes a uniform thickness portion at a radial center, and a decreased thickness portion adjacent to an inner-diameter-side end surface.

Embodiments are directed to solid lubricant assemblies for providing over temperature protection for bearings and gears in rotorcraft systems. A solid lubricant enters a fluid state above a certain temperature and is positioned so that fluid lubricant is applied to the bearings or gears.
