Roller with brush roll between mandrel and sleeve

摘要

A heat resistant roll is useful for supporting and conveying articles for transport at high temperature. The roll has a mandrel core and a sleeve. The sleeve is enlarged over the core to define a radial clearance therebetween. The mandrel and the sleeve have differing coefficients of thermal expansion. Interposed between the mandrel and the sleeve is a brush roll. The brush roll maintains engagement with both the mandrel and the sleeve during thermal expansion.
