FIELD: machine building.
SUBSTANCE: invention refers to a bearing assy used as a support for a tubular element, in particular, to a lower bearing of the sliding tube of shock-absorber strut of the aircraft landing gear. Bearing (2') assy comprises body (3') supporting the first and the second annular supporting portions with the supporting surfaces, which contact with inner tubular element (1') in the areas distanced from each other in the axial direction. The annular supporting portions are represented either by separate supporting rings (4") installed in body element (3') with the supporting surfaces of different diameters, or by one supporting ring (4"), which can bend in the radial direction and is supported in such a way that the second annular supporting part can bend under effect of a load in the radial direction, while its supporting surface will occupy a position with a diameter bigger than the diameter of the supporting surface of the first annular supporting part (4"). Supporting ring (4") is installed in body (3') in seat (5") with shaped base (7") or conical base (9").
EFFECT: removal of a pinpoint contact between a tubular element and a supporting ring reducing wear and pressure.
