ABSTRACT:
An intermediate thrust bearing is positioned between the rotating cutters and its bearing pin of an earth-boring bit. The intermediate bearing is so configured to take outthrust loads, without rotation, that are directed axially against a radially disposed surface of the roller cone journal as the rock bit works in a borehole.
