Abstract: An assembled idler roll having an outer shell and end bearing assemblies. The bearing assemblies each have an outer race and an inner race. The inner race is press fitted onto a roller shaft to an initial position which is spaced inwardly from a final desired position. The outer shell of the roll is restrained and the shaft is reciprocated along its longitudinal axis to determine the degree of axial movement. The inner race of the bearing assembly is moved from its initial position to its final position as determined by the degree of axial movement.

Abstract: An idler roll assembly for conveyors is provided which is particularly adapted for one-shot lubrication. The assembly includes roll mounting bearings having inner races which are mounted on a tubular roll mounting shaft and inner and outer grease seals which define a bearing chamber. Lubricant is admitted to the bearing chamber from a bore in the tubular roll mounting shaft and through a radial passageway which communicates with another passageway defined by the inner bearing race and a channeled portion of the shaft. The outer grease seal is a labyrinth seal comprising a first labyrinth portion fixed with respect to the roll and a second labyrinth portion fixed with respect to the shaft. A grease release lubricant passage is defined between the second labyrinth portion and the shaft.

Abstract: An idler roller assembly for use with a belt conveyor having a roll cylinder supported by spaced roll heads with anti-friction roller bearings whose shaft is larger in the center than at the ends to reduce shaft deflection. The hub supports a pair of spaced seals that frictionally contact the ends of the shaft to seal the bearing assembly.

Abstract: A conveyor pulley that is mounted on a shaft having a bushing keyed thereto. The bushing has a flange that is bolted to a pair of discs and a plate member. The bushing is tapered to provide a wedging fit with the discs and the plate. One of the discs is disposed between the remaining disc with its outer peripheral edge welded to the pulley's rim. The respective discs and plate are welded together at a substantial distance from the shaft.
