ABSTRACT:
An axial bearing includes a ring, pads and a base. Multiple, independent pads are orientated in a curved or circular configuration with respect to one another. The pads are retained by recesses in the base. If the pump is installed in a centrifugal pump, the base is preferably integrated into a front impeller shroud. Each pad conforms in shape and size to a corresponding recess's shape and size. Each pad has a side which faces a face of the ring. Axial clearances between the base and the pads may be controlled by varying the pad heights. Fractured pads can potentially be retained in the recesses. The user may remove individual pads during repair and inspection of the axial bearing.
