FIELD: machine building.
SUBSTANCE: flange and support with hemispherical opposed working surfaces are shaped. Ion-beam etching is used to produce aerodynamic profile at support working surface of diameter D as grooves of equivalent spherical helical lines. Variable depth in groove cross-section is defined by monotone increase in thickness of mask element with cut-outs in direction from connector to support pole. Variable depth in groove cross-section is ensured by making the mask second element as a fixed shield perpendicular to ion flow axis.
EFFECT: high quality and precision of bearing and its aerodynamic profile.
