ABSTRACT:
A hydrostatic support or pressure element, especially for a controlled deflection roll, comprising a sealing or closing ledge having a sealing surface which closes a gap between a plunger of the support element and the supported part in a manner such that mixed friction prevails at the sealing surface of the sealing ledge. The sealing surface has a width which at most amounts to ten or five millimeters, respectively. The hydraulically effective surface of the plunger, producing a contact or press force for the sealing surface, is equal to a surface whose boundary line extends within the sealing surface, and specifically, preferably at a distance of 0.2 to 0.5-fold of the width of the sealing surface from the inner edge of the sealing surface.
