FIELD: technological processes.
SUBSTANCE: invention relates to the field of rolling equipment, namely to sealing devices of working rolls supports, and may be used, for instance in sealing devices of bearing supports of machines and mechanisms. Sealing device of forming roll support comprises bearing unit, nozzle, arranged on shaft journal, cover of bearing with seat for installation of sealing collar, including body, radial and end grips with working edges interacting with according surfaces of nozzles. End grip is connected to radial grip in its end part and is arranged with curvilinear shape, which faces radial surface of nozzle with its concave side, end surface of which is arranged as inclined. Ratio of rigidities in end and radial grips makes 1:3.
EFFECT: invention makes it possible to preserve sealing properties of collar in process of measurement of relative position of rubbing surfaces of roll, and also to increase durability of sealing device and to increase efficiency.
