An object is to provide a self-heat-generating fixing roller that has a simple structure and good durability and that can be easily produced. A self-heat-generating fixing roller according to an embodiment of the present invention includes a columnar core bar, a heat-insulating layer stacked on an outer circumferential side of the core bar, a heat-generating layer stacked on an outer circumferential side of the heat-insulating layer and heated by supplying electricity, and a mold-releasing layer stacked on an outer circumferential side of the heat-generating layer. The heat-insulating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of pores contained in the matrix. The heat-generating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of electrically conductive fillers contained in the matrix.

A ball bearing for the scroll of a scroll compressor, having an outer race, an inner race and a plurality of balls disposed therebetween, characterized in that the balls are held and guided in a ball bearing cage, wherein the ball bearing cage is formed as an externally guided plastic cage with a reinforcing structure made of metal as a hybrid cage.

An insulated bearing has an outer ring and/or inner ring as an insulated ring. The insulated ring has a body with a surface having a material removal portion. An insulating layer is overmolded on the body and molded into the material removal portion. A method of manufacturing the insulated bearing includes having a gate used for an injection molding machine for overmolding the insulating layer arranged so the weld seam of the insulating layer after overmolding avoids the main force-loading area of the insulated ring and/or is formed in the insulating layer where the thickness of the insulating layer is at a maximum. The insulated bearing solves the problem of electrical corrosion of bearings used in high-voltage environments. The insulated bearing achieves good electrical insulation and also prevents axial and/or circumferential movement of the insulating layer, improving the electrical performance and life of the insulating layer and the bearing.

An electrically insulated bearing ring has an electrical insulation layer, the electrical insulation layer including a composite having a synthetic resin as a matrix, a fiber filler for increasing the strength of the composite and a thermally conductive filler for increasing the thermal conductivity of the composite. An electrically insulated rolling bearing incorporates the electrically insulated bearing ring.

Various implementations of a clevis may include a continuous fiber reinforced thermoplastic that may be least partially looped around a first opening in the clevis and a second opening in the clevis. Implementations of a clevis may include a stem and the continuous fiber reinforced thermoplastic may extend into the stem.
