A bearing assembly 100 includes a first rolling-element bearing 110, a second rolling-element bearing 120 and an intermediate ring 130. The first rolling-element bearing 110 comprises an inner ring 112 that is connectable to a shaft 102 in a torsion resistance way. The inner ring 112 of the first rolling-element bearing 110 has a raceway 114 for rolling elements 116 of the first rolling-element bearing 110. The second rolling-element bearing 120 comprises an inner ring 122 that is connectable to the shaft 102 in a torsion resistance way. The inner ring 122 of the second rolling-element bearing 120 has a raceway 124 for rolling elements 126 of the second rolling-element bearing 120. The intermediate ring 130 is disposed axially between the inner ring 112 of the first rolling-element bearing 110 and the inner ring 122 of the second rolling-element bearing 120. The intermediate ring 130 has a maximum outer diameter 132 smaller than a maximum diameter of the raceway 114 of the inner ring 112 of the first rolling-element bearing 110 and smaller than a maximum diameter of the raceway 124 of the inner ring 122 of the second rolling-element bearing 120.
