A APDL program is developed for analyzing the contact stress of journal bearing pair of roller cone bit. The 25 contact stress cases of different clearance fit(including clearance of large bearing is bigger, equal to and smaller than that of small bearing) journal bearing pair of the 8 1/2XXX roller cone bit are analyzed. The result is that the maximum contact stress is less when the clearance of large journal bearing pair is smaller than or equal to that of small journal bearing pair.
