Bearing unit, e.g. for downward drilling motors, has bearing holders with conical running tracks and axes of symmetry that are inclined with respect to main axis of at least one inner ring and/or first outer ring

摘要

The unit has at least one inner ring (1,2) and a coaxial first outer ring (4), whereby an outer contour (15) of the at least one inner ring and an inner contour (10) of the first outer ring form a number of bearing holders (30) with conical running tracks and axes of symmetry (17) that are inclined with respect to a main axis of the at least one inner ring and/or the first outer ring.
