A self-loading type of controlled deflection roll includes, in a preferred embodiment, a pivot assembly which is pivotally mounted to a support shaft near either end of the roll. The roll includes a roll shell having an extension attached to either end which extends co-axially outwardly from the roll shell. These axial extensions of the roll shell are supported by non-self-aligned bearings on the pivot assemblies near either end of the roll. Intermediate the end of the roll shell and the bearings is a heat barrier which prevents hot hydraulic fluid within the interior of the roll from contacting or heating the bearings which rotatably support the roll shell about the self-loading assembly. The bearings can, therefore, be provided with a lubricant which is sealed and shielded from the temperature of the hydraulic fluid within the roll.
