A roller bearing for rotationally mounting a high-speed shaft, such as a shaft for a turbocharger, includes a cage. The cage has two rings and a plurality of connecting elements and cavities for the rolling bodies. The connecting elements extend axially between the cage rings, and the cavities are located between the connecting elements. The cage is made from a metallic material and is formed according to a shaping method, wherein two tangentially adjacent ends of the cage are interconnected in a material fit.

The invention relates to a process for producing a rolling bearing cage, in particular for large rolling bearings, wherein a steel strip with openings for in each case one rolling body is provided and bent to form a ring, wherein, for thermal coating with a thermoplastic powder, the ring is then heated to a temperature above a minimum coating temperature, wherein the ring is then dipped into a fluidized bed comprising the thermoplastic powder, wherein, during the residence time of the ring in the fluidized bed, plastic powder adheres to the ring, melts and forms a continuous coating, and wherein the ring is removed from the fluidized bed after the coating. The invention also relates to an apparatus for carrying out the process.

A rolling element cage for a linear guide system includes two receiving portions and a connecting portion connecting the two receiving portions, wherein each of the two receiving portions includes two extended top surfaces. The two receiving portions each include a plurality of apertures. Each aperture includes a side surface connecting the two top surfaces. At least one of a plurality of bearing rolling elements is receivable in each of the plurality of apertures of the rolling element cage, so that the side surface of the aperture or a transition between one of the two top surfaces and the side surface can be brought into contact with a rolling element surface of the bearing rolling element which is receivable in the aperture. The transition between one of the two top surfaces and the side surface includes, at least in sections, a broken edge, an edge including a chamfer or a rounding.

A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.

A rolling bearing strip for a power operated rotary knife providing bearing support for rotation of a rotary knife blade with respect to a blade housing. The rolling bearing strip includes: a plurality of rolling bearings disposed in spaced apart relation; and a flexible separator cage for positioning the plurality of spaced apart rolling bearings, the flexible separator cage including interlocking first and second ends, the first end of the separator cage including a wall defining a projecting member and the second end of the separator cage including a wall defining a receiving member, the first end projecting member and the second end receiving member being in opposed facing relationship and the first end projecting member extending into the second end receiving member to secure the first end to the second end and form an annular, continuous rolling bearing ring.

A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.

A ball bearing includes an inner ring including an inner ring raceway surface on an outer periphery, an outer ring including an outer ring raceway surface on an inner periphery, a plurality of balls arranged between the inner ring raceway surface and the outer ring raceway surface, and a retainer including a plurality of pocket holes which respectively store the plurality of the balls, and arranged between the inner ring and the outer ring. Grease is sealed between the inner ring and the outer ring. The inner periphery of the outer ring is contacted with outer peripheral surface of the retainer so as to guide the retainer. The inner periphery of the outer ring includes a grease storage groove which communicates with the outer ring raceway surface, only on one side in an axial direction of the outer ring with respect to the outer ring raceway surface.
