A cluster roller assembly used in material handling includes a body member for mounting a driven shaft. The body member includes a periphery having a plurality of roller support positions. A roller is supported at each roller support position. A central bore extends through either end of the roller and defines an axis of rotation. A bearing recess is formed at either end of the roller and a pair of rolling element bearings are each fitted within the bearing recess and each has an inner race. A roller shaft extends through the central bore and the rolling element bearings and engages at either end a pair of support legs for supporting the roller between the support legs. In one aspect, a spacer engages the rolling element bearing and the inner race to pass the thrust of the roller through the spacer to the body member. The rolling element bearings can be sealed.
