Abstract: A conveyor frame and conveyor roll assembly comprising spaced conveyor frame elements defining opposed, noncircular axle receiver slots or openings, as the case may be. A conveyor roll and axle assembly includes a conveyor axle formed of cylindrical stock, such as tubing, and having the extremities thereof formed to a noncircular configuration adapted to be received in nonrotatable relation by the axle receiver slots or openings and defining a cylindrical intermediate portion having stop surfaces at each extremity thereof. Bearings are provided having inner and outer bearing races and rotatable bearings therebetween. The inner race of each of the bearings is received in nonrotatable relation with the noncircular extremities of the conveyor roll axle and is adapted to be engaged by the stop surfaces of the axle to limit axle movement relative thereto.
