Abstract

The invention relates to a rolling bearing arrangement with: a housing (10), a shaft (20), a first rolling bearing and a second rolling bearing for rotatably supporting the shaft in the housing, wherein the first rolling bearing is designed as a fixed bearing in which an outer ring (32) of the first rolling bearing is positionally fixed in the housing and an inner ring (34) of the first rolling bearing is rigidly connected to the shaft, wherein the second rolling bearing is designed as a floating bearing in which the outer ring (42) of the second rolling bearing is arranged axially displaceably in the housing and the inner ring (44) of the second rolling bearing is connected axially displaceably to the shaft, and wherein both the outer ring (42) and the inner ring (44) of the second rolling bearing are each pressed in the axial direction towards the first rolling bearing by a pre-tensioning means in order to prevent a rotation of the outer ring (42) relative to the housing and a rotation of the inner ring (44) relative to the shaft.
