FIELD: testing equipment, namely bearing unit of three freedom degree dynamic bed for simulating angular motions of spatial crafts. SUBSTANCE: bearing unit is in the form of spheric gasodynamic bearing having rotor and stator and multipoint supply of gas such as air through nozzles. Stator has annular grooves communicating with single discharging collector. Tore-shaped collector is mounted on said discharging collector; tore shaped collector is in the form of two fluid-tight ring halves. Each ring half at one side through pipelines by means of throttling washers is communicated with additional compensation groove provided on stator and at other side through throttling valves mounted in pipeline it is open to atmosphere. EFFECT: increased load carrying capacity, improved operational stability of bearing. 1 cl, 1 dwg
