An end thrust bearing arrangement for the shaft of a screw extruder driven by a gear drive, in which misalignment of the gear drive output shaft and the shaft of the extruder screw is compensated by a co-rotation thrust member provided between the screw and a tapered roller bearing which axially supports the shaft of the extruder screw, an end of shaft of the extruder screw projecting through the thrust member and being coupled to the gear drive output shaft to be rotated thereby, and an elastically deformable sleeve surrounding the end of the shaft of the screw and coaxial therewith, one end of the elastically deformable sleeve being attached to the thrust member and the other end being attached to the gear drive output shaft. If desired the thrust member of the elastically deformable sleeve can be formed integral one with the other.
