Abstract: A bearing chocking assembly for mill rolls includes an inner ring engageable with the bearing structure and having on its outer face axially inclined wedge-shaped cam surfaces. These surfaces are arranged to come into contact with similar mating surfaces on the inward face on an outer ring. Both of the rings have circumferential flanges with axial holes around their entire circumference to enable the flanges to be bolted together upon being rotated to effect axial positioning of the assembly. The inner ring rests on a surface of the mill roll shaft and is secured in place by a split thrust ring disposed in the shaft groove. This assembly enables a mill roll to be removed for regrinding and replaced without separating the rings from one another and avoids the need for removing a split inner adjustment ring from the groove. Provision of flanges with holes around their entire circumferences allows for fine adjustments over a wide range of positions.
