A method for the manufacture of bearings, of the type in which rolling members are retained between two pairs of races. A cage constituted by two pairs of races and intermediate rolling members is placed within a mould which has two wedge like elements. As the mould is closed these two elements expand the cage radially outward. Plastics material is then injected into the mould on either side of the cage to encase same.
