A roll for use in glass manufacture, such as in the production of non-dusting TFT glass, includes a hollow silica cylinder. A rod extends through the interior of the silica cylinder. A cooling volume is contained within the cylinder and extends around the rod. End caps are mechanically fixed to the roll. Pulling flats are fixed in place by inner and outer end plates. A compression fitting secures at least the outer end plate to the roll. The rod may serve to reinforce the roll and may be secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion.
