ABSTRACT:
A roll for use under high or low temperature conditions, for example a conveyor roll in a flat glass annealing lehr, comprises a tire of a different material from collars on the roll between which the tire is held. The tire and at least one collar have matching frusto-conical surfaces which are designed so that differential thermal expansion between the tire and the retaining collars causes sliding movement only of frusto-conical surfaces relative to each other.
