Angular contact roller bearings include an inner bearing ring with an inner raceway, which is arranged on the outer shell surface of the inner bearing ring so as to be inclined with respect to the bearing axis of rotation. An outer bearing ring has an outer raceway, which is arranged on the inner shell surface of the outer bearing ring so as to be inclined with respect to the bearing axis of rotation. An integrally formed rim delimits each, and a multiplicity of roller-type rolling bodies are arranged between the bearing rings and roll on the raceways of the bearing rings and are held with uniform spacings to one another in a circumferential direction by a bearing cage.

The disclosure relates to a method for producing an angular contact roller bearing with unilaterally delimiting rims. The disclosure also relates to multiple variants of a device for assembling the angular contact roller bearing. The method may include conically forming an inner raceway into a cylindrical section of an outer shell surface of an inner bearing ring such that the inner raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, conically forming an outer raceway into a cylindrical section of an inner shell surface of an outer bearing ring such that the outer raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, and assembling the inner and outer bearing rings and a multiplicity of roller-type rolling bodies, which roll on the raceways of said bearing rings, in accordance with an eccentric assembly method.

Angular contact roller bearings are disclosed. The bearing may include an inner bearing ring with an inner raceway, which is arranged on the outer shell surface of said inner bearing ring so as to be oblique with respect to the bearing axis of rotation (AL), and comprising a rim which delimits said raceway at its smallest diameter. An outer bearing ring has an outer raceway, which is arranged on the inner shell surface of said outer bearing ring likewise so as to be oblique with respect to the bearing axis of rotation (AL), and a rim which delimits said raceway at its greatest diameter. A multiplicity of roller-type rolling bodies are arranged between the bearing rings and roll on the raceways of said bearing rings and are held with uniform spacings to one another in a circumferential direction by means of a bearing cage. A tangent to the outer shell surface of the inner bearing ring and a tangent to the inner shell surface of the outer bearing ring are, at least in the region of the raceways, of planar form so as to run in opposite directions obliquely with respect to the bearing axis of rotation (AL). The raceways of the two bearing rings are each formed in conical fashion into said shell surfaces and the rims which are thus formed and which delimit the raceways in each case on one side are thus each formed integrally with the bearing rings.

A spherical roller bearing having a specific pitch circle diameter (PCD) that includes an outer ring, an inner ring, a plurality of roller elements arranged in first and second roller rows, each roller element providing an axially inner end, and a cage for guiding the roller elements in the first and second roller row, the cage having a plurality of cage pockets. One of the roller elements disposed within each cage pocket. Each respective cage pocket has a bottom that faces the axially inner end of the roller element in each cage pocket. A radially inner end of the cage pocket bottom contacts the axially inner end of the roller element only at a location radially equal to the specific PCD, the cage pocket bottom angled such that the cage pocket bottom abuts the axially inner end of the roller element at an angle such the contact is not flush.
