A conveyor construction includes a frame, a drive section stationarily mounted to the frame, and a tensioning section mounted for longitudinal movement relative to the frame. The drive and tensioning sections each include a spindle, and a belt is engaged with the spindles. The frame defines an upper support surface disposed below the upper run of the belt, and mating engagement structure is provided on the belt and the upper support surface for preventing lateral movement of the belt relative to the upper support surface. The drive and tensioning sections include spaced side members, each of which defines an inwardly opening cavity for receiving a bearing assembly for rotatably supporting the spindle. The bearing-receiving cavity faces the spindle, and each side member defines outer wall structure which engages and supports the belt outwardly of the spindle. The belt overlies the outer wall structure of each side member and the adjacent belt-engaging portion of the spindle, so as to seal the inwardly facing opening and prevent ingress of moisture or other contaminants into the bearing-receiving cavity.

[ We claim:] [1.] A spindle mounting arrangement for a conveyor construction including a belt and a spindle about which the belt is trained, comprising a spindle mounting member including end wall structure and laterally extending wall structure which cooperate to define an inwardly open cavity, and a bearing arrangement disposed within the cavity for rotatably mounting the spindle to the spindle mounting member, wherein the laterally extending wall structure defines an outwardly facing belt engagement surface and defines an opening to the cavity which faces the spindle, and wherein the end wall structure and the laterally extending wall structure of the mounting member are configured so as to enclose the cavity from the exterior of the mounting member, wherein the belt engages the spindle and the belt engagement surface defined by the laterally extending wall structure to prevent access to the cavity from the opening to the cavity defined by the laterally extending wall structure.
