FIELD: belt conveyer roller supports.
SUBSTANCE: proposed roller has cylindrical shell, bearing units, external seals, axle and inner pipe separating the shell cavity from bearings. Chambers formed between external seals and bearings are filled with porous material impregnated with oil. In case of pressure differential between outside atmosphere and atmosphere in inner cavities of rollers, dust-laden air overcomes action of seals and enters the said chambers where dust is held reliably.
EFFECT: increased service life of bearing units.
