Construction hybrid gas bearing• The hybrid bearing combines the advantages of

gas-static and gas-dynamic. • By combining of the operation modes, it is

possible to achieve complete absence of dry friction during the whole cycle of work. • Use of fluidic control system and the special

geometry of the segments allows the bearing to withstand overload up to 6 g.
