ABSTRACT:
Stub idler units for a flexible sidewall belt conveyors support the return belt run. Each unit includes a stub roll fixed to and forming an integral part of a solid shaft. A pair of re-lubricable, sealed bearings are mounted within opposite ends of a tubular bearing housing secured within a tubular mounting bracket. The shaft is journaled in the bearings clamped to the housing by a locking nut on the shaft end. A lubrication passageway is formed in the mounting bracket and housing and provided with a lubrication fitting. The passageway connects to the chamber between the bearings lubricating the bearings. A flexible hydraulic grease line is attached to the far side mounting bracket in place of the grease fitting. The grease line extends across the conveyor belt to the near side of the conveyor and terminates in a grease fitting for re-lubrication of the far side stub idler. The line is supported at the two mounting brackets by suitable shaped support elements mounted to the mounting brackets.
