Abstract
A rotating member, such as a roll of paper is supported by a pair of shafts extending into opposite ends of an axial bore in the rotating member. The shafts, which have rubber bushings which expand outwardly into tight fit within the axial bore, are constructed to enable ready removal of the shafts from the roll, for example, to change the roll.
