FIELD: mechanics.
SUBSTANCE: invention relates to sealing technology. Sealing ring is implemented with sealing edge, which sealed enveloping sealed shaft with radial tightness, herewith sealing edge on directed to shaft surface allows surface profile, implemented in the form of recurrent facility of device. Sealing edge on its free end allows at least one enveloping projection, which projects the surface profile.
EFFECT: invention improves reliability of sealing.
