ABSTRACT:
A bearing apparatus for permitting axial rotational and angular movement of a doctor journal of a papermaking machine, includes a housing which defines a cylindrical bore for the reception therein of the doctor journal. An annular bearing ring defines an inner and an outer surface with the outer surface being cylindrical and having a diameter slightly less than the diameter of the bore such that when the ring is disposed within the bore, axial sliding of the bearing ring within the bore is permitted. A sleeve is disposed within the bearing ring with the sleeve defining an internal channel for supporting the doctor journal. The sleeve also defines an external face which closely conforms to the inner surface of the bearing ring such that angular movement of the sleeve within the bearing ring is permitted while axial movement of the sleeve relative to the bearing ring is inhibited.
