ABSTRACT:
A mill roll is supported at its roll necks on tapered roller bearings, each having several cones and corresponding cups and rows of tapered rollers between the raceways of each cone and cup. Each bearing also has rib rings located at the ends of its cups to provide surfaces against which the large diameter ends of the rollers in its several sets bear. The cups and rib rings are clamped together within a chock, and they, in turn, capture the several rows of rollers. The cone raceways taper downwardly away from the roll body and lie within a single conical envelope having its center along the axis of rotation for the bearing. This arrangement allows the chock, which carries the cups, rib rings and rollers, to be passed over the cones on the roll neck. The roll body is ground while the roll is supported on the bearings that are within the chocks and with the bearings in a condition of preload. This eliminates practically all eccentricity, so runout is maintained at a minimum. The bearings B are also maintained under preload during mill operation.
