The bearing pedestal for the rotating shaft 12 includes journal and axial thrust bearings 16 and 26, respectively. Both of the journal and thrust bearings have passages 70 and 80, respectively, and recesses 74 and 82 in the respective pad faces for flowing high pressure lubricant between the pads and the shaft to displace the shaft and pads relative to one another to minimize the required breakaway torque and metal-to-metal contact. Each thrust bearing includes a plurality of circumferentially spaced pads 26 and lubricant directors 30 between the pads. The lubricant director includes a rib 34 extending generally tangentially and radially outwardly to channel lubricant from a preceding pad to a succeeding pad in the direction of shaft rotation and to channel the lubricant for flow tangentially from the thrust bearing into an annular cavity 39 for return to sump 42. An end seal assembly 40 includes an element 44 having internal and external labyrinth seals 54 and 55 straddling an annular groove 50 opening onto the shaft. An annular recess 48 is provided along the inner surface of element 44 to receive lubricant splashed from the tangential flow and direct it into the cavity. Drain back openings 56 and 59 flow lubricant from the labyrinth seals into the cavity 39.

A bearing assembly for a rotatable shaft having annular and cylindrical bearing faces, comprising: journal and thrust bearings, said thrust bearing including a pad for disposition in opposition to the annular shaft bearing face; means defining a cavity about said thrust bearing; means forming part of said thrust bearing for directing lubricant from adjacent the shaft between said thrust bearing pad and the shaft bearing face into said cavity; an end seal assembly including an element carrying a labyrinth seal surrounding the shaft at a location spaced axially of the shaft bearing face and on the side thereof remote from said thrust bearing for deflecting lubricant migrating along the shaft past the thrust bearing, said element having a recess for receiving the deflected lubricant from the labyrinth seal and opening into said cavity for flowing the deflected lubricant into the cavity; and said element having a lubricant catcher groove spaced axially from said labyrinth seal on the side thereof remote from the shaft bearing face, said groove opening along said shaft, said element having an opening in communication with said groove and said cavity for flowing into said cavity lubricant leaking along the shaft past said labyrinth seal and into said groove.
