A bearing arrangement includes a bearing outer element that defines a first plurality of races opening radially inwardly, a bearing inner element that defines a second plurality of races opening radially outwardly, and a bearing middle element defining a third plurality of races at its radially outer surface thereof and a fourth plurality of races at its radially inner surface thereof. Rolling elements are receivable in the races. The bearing middle element includes an axial protrusion at least at one end thereof that can be received in a housing with respect to which the bearing outer and inner elements are rotatable.
