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.
