A bracket assembly for receiving the shaft end of a distribution roller in a printing, duplicating or like machine. A pin head structure is mounted on a framework of the machine. The pin head structure includes an axially inwardly facing abutment surface against which the shaft end of the roller can abut when in proper position in the machine. A latch member is movably mounted on the pin head structure for radially containing the roller in its proper position and for allowing removal of the roller in the radial direction. The latch member is movable from a first position disposed axially outwardly of the abutment surface to permit the roller to be radially moved into and out of its proper position in the machine, and a second position disposed axially inwardly of the abutment surface overlying the shaft end to contain the roller in its proper position in the machine.
