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.
