Abstract
A bearing assembly is for supporting a shaft in a housing, preferably a rotor shaft of a centrifugal compressor. The bearing assembly includes at least a first bearing pair including a first rolling bearing and a second rolling bearing arranged back to back, each one of the first and second rolling bearings including an inner ring attached to the shaft, an outer ring and a plurality of rolling elements disposed between the inner ring and the outer ring. A radial gap is provided between the outer ring of the first rolling bearing and the housing and the outer ring of the second rolling bearing is in contact with the housing. Preferably, a fixing element restricts axial movement of the outer ring of the first rolling bearing with respect to the housing.
