A bearing unit has a housing, shaft pin and not less than two roll bearings as bearing hollow rollers mounted with gap on hollow axles with radial openings, system for gas supply under pressure, this is connected through radial openings with gaps between bearing hollow rollers a and hollow axles, and closed flexible link. In the housing of bearing unit not less than one tension unit is installed, this consists of tension plug with feeders, it is placed with controlled gap on hollow pin with radial openings. Flexible link surrounds each of tension units and is placed between the pin of the shaft and hollow bearing rollers. Contact of flexible link with each of tension plugs is realized through gas layer formed by working medium supply to feeders of tension plug.
