ABSTRACT:
A roll mandrel has a tubular center section and a plunger slidable in each end, each of the plungers having a plurality of journal sections of different diameters. The plungers are slidable to adapt the mandrel to a variety of spaced brackets that may have different bearing section diameters, at least one of which is radially open. The plungers are held in adjustable axial position by the friction of O rings against the inside of the central tube.
