Claim:
Method for manufacturing a bearing support, particularly for a fan casing, comprising the following steps: placing a bearing assembly in correspondence to a matrix die of an injection mold, said bearing assembly comprising at least two bearings coaxially arranged and axially spaced apart from one another by at least one spacer member, said bearing assembly defining a central axial bore; abutting a punch of said injection mold on the bearing assembly to coaxially align and axially clamp said bearing assembly so as to prevent penetrations of material to be injected inside the central axial bore and the bearings; and injecting a plastic material into the mold to form an assembly sheath over-injected on outer surfaces of the bearing assembly and an annular body produced integrally with said assembly sheath, wherein said annular body defines at least a portion of a fan casing adapted to contain an impeller.
