FIELD: mechanical engineering. SUBSTANCE: proposed system of two articulated objects with provision of two degrees of freedom at rotation relative to axes X and Y contains bearing with inner enclosed race on geometric axis X and installed inside enclosing race according to ball joint type. Inner enclosed race and outer enclosing race are coupled at rotation relative to axis Z by means of two support surfaces located between two enclosing surfaces in outer race, said surfaces being made detachable. EFFECT: increased mechanical strength, reduced overall dimensions. 7 cl, 6 dwg
