The invention relates to a sealing system supporting-rotating shaft and can be used in pump, compressor engineering, in mixing devices. Proposed block supporting-sealing system of the rotating shaft, comprising a housing, a sealing and supporting units, the latter of which consists of the rotating and non-rotating parts, the sealing shaft by reacting at its end an antifriction ring of the sealing assembly and the rotating part of the support assembly, sealingly mounted on the a shaft, by means of two rubber rings, the rotating part of the support assembly is made of antifriction material and directly contacts the stationary part supporting ties and made of antifriction material, wherein the entire length of the outer surface of the rotating part of the supporting unit or the entire length of the inner surface of the fixed part of the support unit formed with longitudinal grooves, wherein the O-rings mounted on the edges of the rotating part of the support assembly. On the opposite side of the support assembly may be mounted a second sealing unit, identical to the first, forming a seal on the shaft Scheme double seal. The grooves may be formed on the inner surface of the screw portion of the rotary support assembly. 2 nezav.p. f-ly, 2 zav.p. f-ly, 4 Fig.
