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. A tubular roll element is provided and the outer portions of each of the bearings is positioned in nonrotatable relation within the extremities of the roll element for drop-in type axle installation the noncircular extremities of the axle may be of the same length. For free-hole type installation, one of the noncircular extremities of the axle is of greater length than the other extremity enabling the axle to be moved through the receptacle hole of the conveyor frame sufficiently to allow the opposite extremity of the axle to be inserted into the hole receptacle of the opposite frame member.
