Abstract:
A double row roller bearing which has an outer and inner bearing ring and ball rollers, which have lateral faces and are arranged next to each other in rows, arranged between the bearing rings. The rollers roll in raceways incorporated into the inner face of the outer bearing ring and outer face of the inner hearing ring. The raceways run in parallel and have pressure angle axes that are pitched at a pressure angle relative to a bearing radial axis. The rollers have a distance relative to each other which excludes mutual frictional contacts. For this purpose, the distance of the pressure angle axes of the raceways is enlarged and both rows of rollers are guided in separate bearing cages, while the raceway of the rollers of the row with the larger reference circle arranged on the inner bearing ring has a one-sided axial extension using the distance.
