An air cooled bearing assembly for the armature shaft of an electric motor comprises a heat sink with an axial bore and spaced outwardly extending fins along its external surface. The fins are of a greater depth over part of their length and the junction between the parts of different fin depth is round to form a seating for a resilient mounting member. Located in the bore is a bearing sleeve which is an interference fit in the bore.
