ABSTRACT:
A replacement drive roll having an integral bearing for easy replacement and universal usage in a printing machine. The roll member has a bearing having a nonround outer race for retention in a frame member and a nonround inner race for engagement with a driveshaft on one end. The opposite end has a locking member for preventing axial movement along the shaft. The roll assembly has elastomer bands stretched around the outer circumference to form the drive surface of the roll. The roll unit is easily replaced and can be used in numerous locations thereby reducing parts inventory requirements.
