FIELD: engineering.
SUBSTANCE: invention relates to a rotary component (1) with one degree of freedom, containing at least two concentric rings (10, 20) movable during rotational motion relative to each other around the central axis, wherein a friction area (40) is formed between said rings including: an outer ring (10) with an inner friction surface (12) and an inner ring (20) with an outer friction surface (22) and an inner friction surface (24) intended to accommodate a movable part guided by the component (1) during rotational motion, oscillatory motion and/or translational motion. The friction area (40) between the rings (10, 20) accommodates the lubricating material (L), wherein the component (1) comprises a sealing agent (60) intended to prevent leakage of the lubricating material (L) from the friction area (40).
EFFECT: provided rotary component, in particular, with excellent resistance to wear and formation of scratches and with an extended service life.
