  • Idler roll bearing assembly
    Patent number: 6641512
    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.
