Abstract:
1. A continuous metal extruder, comprising: a rotatable member having an extrusion screw portion for transporting metal to be extruded in an axial direction of said rotatable member, a fixed part, a spring element for biasing the rotatable member and the fixed part in relation to each other, and a thrust bearing arranged between the rotatable member and the fixed part, said thrust bearing having a first bearing race facing said fixed part and a second bearing race facing a part of said rotatable member, wherein said spring element is arranged to provide an expanding biasing force, in said axial direction, between the first bearing race of the thrust bearing and the fixed part, wherein the entire thrust bearing is axially movably mounted relative the fixed part, and wherein the spring element is able to exert said expanding biasing force so as to provide at least a sufficient force to move the thrust bearing when the thrust bearing is positioned horizontally.
