  • Publication number: 20090196947
    Abstract: A continuous metal extruder that comprises a rotatable member having an extrusion screw portion for transporting metal to be extruded in an axial direction of said rotatable member, and a fixed part, is disclosed. In a method the rotational member and the fixed part are biased in relation to each other. An extruder for carrying out the method comprises a spring element for the biasing. In one embodiment there is a thrust bearing arranged between the rotational member and the fixed part, said thrust bearing has a first bearing race facing said fixed part and a second bearing race facing a part of said rotatable member. The spring element is arranged to bias the thrust bearing, and thereby the rotational member and the fixed part in relation to each other, by exerting along said axial direction an expanding force between at least one of the of the following: the first race of the thrust bearing and the fixed part; and the second race of the thrust bearing and said part of the rotatable member.
