Abstract:
Two hybrid ball bearings and a compressor bearing arrangement with two hybrid ball bearings for a rotatable support of a rotor of the compressor versus a stator of the compressor. The two hybrid ball bearings are arranged face-to-face or back-to-back, are configured with an optimal axial clearance depending on the inner diameter of a ring-shaped inner raceway element one of the hybrid ball bearings respectively a pitch diameter of one of the two hybrid ball bearings for a long bearing life in connection with an optimal compressor operating performance.

Claim (Index 15):
A compressor bearing arrangement comprising:\n two hybrid ball bearings for a rotatable support of a rotor of the compressor versus a stator of the compressor, wherein the two hybrid ball bearings have an axial clearance with zero mounting loads, comprising:\n a first hybrid ball bearing, comprising a first inner ring and a first outer ring, the first outer ring having a first inner diameter on which a first plurality of balls roll thereon; \n a second hybrid ball bearing comprising a second inner ring and a second outer ring, the second outer ring having a second inner diameter on which a second plurality of balls roll thereon; \n wherein one of: (1) the first inner ring and the second inner ring, or (2) the first outer ring and the second outer ring are axially aligned and in abutting contact, and the other one of: (1) the first inner ring and the second inner ring, or (2) the first outer ring and the second outer ring are axially aligned and spaced so as to define an axial clearance therebetween, wherein the axial clearance is less than or equal to seventy micro-meters (70 \u03bcm).
