It is specified for this purpose that the inner ring of the rolling bearing has a greater axial length with respect to the axial length of the outer ring of the rolling bearing by a section of the inner ring that corresponds to the axial length of the outer ring and has the length being adjoined by additional sections, wherein the axial lengths of these sections differ in size.

Abstract: A reduction in the setting of rollers in a self-aligning roller bearing is provided. The self-aligning roller bearing has inner and outer bearing rings and rollers arranged at least in one roller row. The rollers have a curved lateral surface the direction of the rotation axis and has a radius, and roll over curved raceways of the bearing rings. The raceways are each assigned a groove point around which the curved raceway extends at a radial distance in the direction of the rotation axis. A pressure line intersects the rotation axis at an angle of 90° at a point where these rollers have their largest roller diameter, and the radius of the curved lateral surface is smaller than both radial distances.

Abstract: A radial rolling bearing (10) with rolling bodies (24) which are received in at least one cage (26, 28) and which are arranged between an inner ring (20) and an outer ring (22). The radial rolling bearing (12) is radially separable, and the radially multipart inner ring (20) can be fixed on a shaft (16) using two clamping rings (36, 38) which are attached to the axial ends of said inner ring. The inner ring (20) is designed without rims on the axially outer sides, and the clamping rings (36, 38) take on the function of inner ring rims, the rolling bodies (24) running against inner run-on surfaces (50) of the clamping rings (36, 38) in the axial direction. On the basis of the at least partial positioning of the clamping rings (36, 38) axially below the cages (26, 28) or the outer ring (22), the clamping rings (36, 38) take on two additional functions in addition to the actual clamping ring main function of fixing the inner ring (20) on the shaft (16).

Abstract: A sealed anti-friction bearing (1), including an annular sealing washer (11, 12) which seals a rolling-body chamber (7) in the axial direction, wherein the sealing washer (11, 12) has a fastening section (14) for connecting it fixedly to a bearing ring (2) of the anti-friction bearing (1) so as to rotate with it, and wherein the sealing washer (11, 12) is anchored with its fastening section (14) in a circumferential groove (22) of the bearing ring. According to the invention, it is provided that the fastening section (14) has a first clamping element in the form of a barb (19) and a second clamping element in the form of an annular bead (20), and that the barb (19) and the bead (20) enter into a non-positive connection with oppositely lying surfaces of the groove (22).

Abstract: A toroidal bearing (1) including a multiplicity of barrel-shaped rolling bodies (7) which roll about a bearing axis (8) between an outer ring (2) having a raceway (3) and an inner ring (4) having a raceway (5) is provided. According to the invention, on a circumferential surface (9) facing away from the raceway (3, 5) thereof, the outer ring (2) and/or the inner ring (4) has at least one lubricating groove (10), wherein the lubricating groove (10) is connected to the raceway (3, 5) via at least one lubricating bore (11).

Abstract: A printer or copier has an intermediate carrier for applying toner to the recording medium. Used toner is scraped off the intermediate carrier and carried away by a conveyor helix. The conveyor helix is of a spring wire and a resistance element is provided extending between coils of the conveyor helix to intermittently catch and release the spring wire so as to cause wobbling of the conveyor helix and prevent sticking of the used toner.
