Belt conveyor roller assembly - has hub with lubricated tapering portion between sealing flanges at ends

摘要

The roller is particularly for plate-type belt conveyors, and comprises a hub (12) with a sealing flange (14) at one end. A separate covering sealing flange (18) is positioned at the other end. A roller section (26) rotates on the hub, which has a tapering portion (44) between the ends, to which there leads from one end a lubricant drilling (50). Hub and roller can have bearing faces working together, the tapering portion forming an annular passage (48) between them.
