2085882 9119854 PCTABS00008 A controlled deflection roll (10) has a unique liquid barrier and heat shield (72) which includes a chamber (82) filled with cooling fluid. In a preferred embodiment, the barrier comprises two chambers (82, 84) and a space (68) in fluid communication with both chambers (82, 84) for circulating cooling fluid between the chambers and into and out of the roll. The barrier (72) is interposed between the interior cavity (20) of the roll (10) containing the extremely hot hydraulic fluid which actuates the apparatus for controlling the deflection of the roll (10), and the bearings (54, 56) which rotatably align the roll shell (18) relative to the space (68). The barrier (72), thus, functions to thermally insulate the bearings (54, 56) from heat, whether by radiation or by direct contact with the hydraulic fluid.
