A controlled deflection roll is disclosed comprising a roll shell rotatable about a stationary beam and at least one hydrostatic support element therebetween. The support element is in the form of a piston tiltably guided in a cylindrical bore formed in the beam and the roll is provided with a seal for sealing off the intermediate space between the piston and the wall of the bore. The seal includes a sealing member disposed in a circumferential groove formed in the wall of the bore which is in seal-tight engagement with the piston and is support on at least one of its sides by an annular support member positioned in the groove and extending part way into the intermediate space. |
