Two hybrid ball bearings and a compressor bearing assembly with two hybrid ball bearings and for a rotatable support of a rotor of the compressor against a stator of the compressor. The two hybrid ball bearings are arranged front-to-front or back-to-back, with optimum axial play, depending on the inner diameter of an annular inner race member of one of the hybrid ball bearings and a pitch diameter of one of the two hybrid ball bearings, for a long bearing life designed in conjunction with an optimal compressor operating performance. |
