FIELD: manufacturing technology.
SUBSTANCE: invention relates to sliding ring seal for devices used for transfer of fluid media, such as liquid, gas or their mixtures with solid particles, in particular for fans and pumps, as well as for other devices axial shafts sealing. Sliding ring seal comprises first rotating friction surface (1), having first diameter and designed for rotation together with rotary transfer facility (18), and second rotating friction surface (6), having second diameter and designed for rotation together with rotary transfer facility (18). First fixed friction surface (2) is located near first rotating friction surface (1) and is attached to fixed structure, and second fixed friction surface (7) is located near second rotating friction surface (6) and is attached to fixed structure. Diameter of second fixed friction surface (6) is larger than that of first rotating friction surface (1), and these friction surfaces (1, 6) are located relative to rotating shaft (19) so, that second friction surface (6) is located further from central axis of rotating shaft (19), than said first surface and said fixed surfaces are located nearby said rotating friction surfaces.
EFFECT: higher reliability of device.
