14 The door suspension system comprises a rail support (1) attachable to a crosspiece (2) of a door and having a part shaped as a rigid substantially flat plate (3) which supports a rail (4). A pair of brackets (8) comprising each a connector (9) are attached to supporting means (10) which have an opening (11), in which the rail (4) is partially introduced. Said connectors (9) have a substantially C-profile embracing the flat plate (3) and the rail (4). A support piece (12) is attached to the connectors (9) and provided with connection means (13) for the suspension of a door (14) of a lift. A magnetic way (16) is attached to the plate (3) and an elongated primary (15) of a linear motor is attached to the strip (12) in such a manner that the attraction force between the magnetic way (16) and the primary (15) cancels at least partially the weight of the door (14). The door suspension system further comprises a bearing of substantially cylindrical shape with an axial recess. Said bearing is mounted in said opening (11) of the supporting means (10) and said rail (4) is introduced in said recess.
