ABSTRACT:
A center-free rolling bearing assembly for machine tools comprising a disk-shaped outer ring, two adjacent outer raceways on the inner radial edge of the outer ring which converge conically together in an axially and radially inward direction, an inner ring, two conical inner raceways on the lateral surface of the inner ring, one in parallel with each outer raceway, and a row of cylindrical rolling elements between each outer raceway-inner raceway combination. The rolling elements of each row are guided laterally by the side surfaces of inner and outer guide flanges forming a single piece with the inner ring. The outer raceways form a single piece with the outer ring and the inner raceway form a single piece with the inner ring. At least one of the two outer guide flanges are formed by an outer flange ring which can be fixed in place on a seating section of the lateral surface of the inner ring, so that the rolling elements can be installed between the two outer and inner raceways.
