The head (11) (40) of a belt conveyor roller is press-fit into a cylindric shell (10) of the roller. The head (11) (40) defines a bearing chamber (12) for a frictionless bearing (14-15; 42) which is closed by a ring assembly (21, 29) welded to the head and provided, in the ebmodiment disclosed, with a stainless steel lamella (33, 59) the opening (60) of which bites into the resilient outer cylindric surface (61) of a hub section (28, 53), to provide a virtually hermetical enclosure of the bearing chamber (12, 41) thus increasing the safety of the operation by isolating the possible point of ignition or explosionon seizure of the bearing (14-15; 41) of the roller. The roller equipped with the assembly of the present invention thus presents a further improvement in the art of belt conveyors for use in hazardous environments.
