A bearing carrier for a shaft of an electric motor has a carrier member supporting two bearings supporting the shaft. The carrier member has a single bearing seat accommodating the two bearings to ensure the two bearings are coaxially mounted. A spacing member axially separates the two bearings. The spacing member has a central passage through which the shaft extends with radial play, as well as two end surfaces parallel with each other, orthogonal to the axis of the passage and axially separated by a distance which corresponds to the desired mounting distance between the bearings. During assembly, the bearings and spacing member are mounted on the shaft to form a preassembled group. The preassembled group is pressed into the bearing seat of the carrier member, with one bearing being pressed against a stop formed at one end of the bearing seat.
