Claim:
1. A bearing assembly system installed in a rock crusher having a main frame, a main shaft, an eccentric and a crushing head, said bearing assembly system comprising: (a) a first bearing ring, said first bearing ring being disposed around the main shaft and on the eccentric; (b) a second bearing ring, said second bearing ring being disposed adjacent to the first bearing ring and the main frame; (c) a third bearing ring, said third bearing ring being disposed around the main shaft and on the eccentric; (d) a fourth bearing ring, said fourth bearing ring being disposed adjacent to the third bearing ring and on the crushing head; (e) a means for conveying fluid to at least one of the first bearing ring and the second bearing ring and to at least one of the third bearing ring and the fourth bearing ring, said means for conveying fluid being adapted to convey a pressurized fluid; wherein at least one of the first bearing ring and the second bearing ring and at least one of the third bearing ring and the fourth bearing ring comprises a substantially closed fluid depression that is adapted to receive and collect the pressurized fluid, said substantially closed fluid depression comprising an inner circumference fluid depression wall that substantially prevents the pressurized fluid from being conveyed radially inwardly from the bearing rings and an outer circumference fluid depression wall that substantially prevents the pressurized fluid from being conveyed radially outwardly from the bearing rings; and wherein the first bearing ring and the second bearing ring are adapted to be hydrostatically separated before start-up; and wherein the bearing assembly system conveys thrust loads directly to the main frame.
