Abstract
A multiple-row and axially biased angular ball bearing with a one-piece outer ring and an inner ring that has two inner ring halves. In order to facilitate an easy and precise setting of the desired pretensioning force and to produce a transport-safe mount cartridge, it is intended that the axial distance of at least two close-end contact surfaces of the angular ball bearing should be equal to zero in the pretensioned state, and that the axial distance of at least two close-end contact surfaces of the angular ball bearing should be greater than zero in a nonpretensioned state.
