Abstract
Stub idler roll units for flexible sidewall belt conveyors are mounted to support the return run of a sidewall belt. The stub idler roll unit includes a stub roll fixed to and forming an integral part of a support shaft. The shaft extends from the roll and is journaled in a pair of re-lubricable, sealed bearings, secured with a tubular bracket having a mounting plate for mounting of a roll unit to the conveyor. A tubular bearing housing is secured within the bracket and has end recesses to receive a bearing and end washer. The outer end of the shaft is threaded and the shaft and roll is clamped to the housing by jam nuts on the outer end of the shaft, the washer abuts the housing to take the clamping load and insure adequate operating clearances. The shaft has an axial passageway extending from the outer end of the shaft and provided with a lubricating fitting. Internally, the shaft passageway has an offset extension to a chamber between the bearings for supplying lubricant to the bearings with a low pressure grease gun. The bracket has a mounting plate with laterial slots for positioning the roll with respect to the belt sidewalls.
