ABSTRACT:
A bearing arrangement, designed in an X-configuration for a planet gear is provided with two angular roller bearings mounted a certain distance apart. Barrel-shaped needles have a large radius of curvature and their length is considerably greater than their diameter. Raceways of the two angular roller bearings have a circular curvature, center of which is located in the radial direction, outside the raceway diameter and in the axial direction, between inner lateral surface and axial center of angular roller bearing in question. As a result, the bearing arrangement is able to pivot slightly even though its dimensions are very small and can also absorb axial loads.
