work not shown supported by the heat resisting rolls 3 is carried on the ceramic sleeve 6 that is caused to rotate by the support roll 4 in an entirely unconventional manner the rotating force of the support roll 4 is transmitted by friction to the ceramic sleeve 6 rather than by fasteners such as pins or keys therefore nicks or cracks that can occur in the vicinity of such fasteners are entirely absent from the heat resisting roll of the present invention preferably at least one of the two sliding surfaces i e the inner surface of the sleeve and the outer surface of the support roll is finished to such a roughness that r max u2267 25 u03bcm by suitable adjustment of the roughness of the outer surface of the body 5 of the support roll 4 or the roughness of the inner surface of the sleeve 6 or alternatively by adjusting the weight of the sleeve a sufficient friction is developed between the support roll 4 and the sleeve 6 to enable the sleeve 6 to rotate in synchronism with the line speed therefore the sleeve 6 is also free from brittle fracture that would occur due to impact from the driving of the sleeve by means of keys or pins as another feature of the present invention a radial clearance 7 is provided.
