Temperature control for shell type rolls

In a shell type roll mounted for rotation on a non-rotatable beam received in the inner race of a triple race bearing, the middle race of the bearing being flexibly connected to the shell roll for rotation therewith under conditions of axial misalignment and the outer race of the bearing being carried by a support, means acting between the beam and the shell roll whereby the shell roll is maintained in a substantially constant nip load condition along its length and the beam bends from the support provided by the inner race;

• the improvement comprising temperature control means for the shell roll including passages extending lengthwise in the shell roll adjacent its periphery, conduits extending through the middle race to a central axial bore in an extension of the middle race, flexible means connecting the passages and the conduits to accommodate conditions of misalignment between the middle race and the shell roll, and means including a rotary joint connecting portions of the central bore to an inlet and an outlet for circulating temperature control fluid through the roll passages.
