Bearing set with an angular ball bearing and cylinder roller bearing receiving axial forces

technical field [0001] The invention relates to a bearing set for a narrowly and precisely guided shaft or the like in the axial direction, for example a rotor or other machine components. Background technique [0002] In all areas of machine construction in which impellers, such as fan wheels etc., must be axially guided very narrowly relative to the surrounding structure, especially when supporting axially very precisely guided shafts , for example on drive shafts, bearing sets consisting of various bearing types are used. [0003] Bearing sets consisting of four-point contact ball bearings (so-called QJ bearings) and radial bearings with ribs on the outer ring (so-called NU bearings) are usually used. Such a bearing combination is known, for example, from the publication WL 00 200 / 5 DA S.150 of the FAG company OEM and Trade AG. In this case, the combination is used for a combined shaft-mounted transmission and herringbone gearing. [0004] A disadvantage here is that f...
