Angular contact rolling-element bearing, especially double row ball roller bearing in tandem arrangement

An angular contact bearing, comprising:

• an outer bearing ring;
• an inner bearing ring;
• and a plurality of ball rollers arranged between the bearing rings and held at uniform distances from one another in a circumferential direction by at least one bearing cage,
• the ball rollers each have two respective lateral faces arranged parallel to one another which are flattened symmetrically from a spherical basic shape and are arranged with a vertical offset one beside the other in two rows with different reference circle diameters,
• the ball rollers of the two rows running with running faces in two respective groove-shaped raceways worked into an inner face of the outer bearing ring and into an outer face of the inner bearing ring, the raceways having pressure angle axes pitched at a pressure angle with respect to a bearing radial axis,
• wherein adjacent ball rollers of the two rows have a distance from one another which excludes mutual frictional contact through enlargement of a distance between the pressure angle axes of the raceways and through guidance of the two rows of the ball rollers in two separate bearing cages, and at least one of the raceways, arranged on the inner bearing ring, of the bail rollers of one of the two rows with a larger reference circle being configured on one side with an axial extension which utilizes the distance.
