Abstract
A conveyor-belt cylinder has a jacket (1) mounted on a shaft (4) by way of a base (2) and a roller bearing (3) at each end. Each base and bearing is secured by an annular spring (15) and sealed with a labyrinth seal comprising an inner ring (7) and an outer ring (8). The spring is inserted in an annular groove (16) in the shaft. A terminating cap (12) engages the outside of an outward-facing annular flange (10) on the inner seal ring and of another outward-facing annular flange (11) on the outer seal ring. The seal rings constitute stitute a prefabricated assembly in conjunction with the terminating cap. The side of the inner seal ring facing the bearing has an annular recess that accommodates the spring.
