The number of scientific articles dealing with hydrostatic bearings has jumped significantly over the last decade due to the huge increase in the development of the Far East industry. With new numerical calculations and simulations, the shape of the bearing pads, the fluid film thickness can be optimized and the behaviour of special hydrostatic bearing designs can be tested. Considering the research results revealed, new directions for optimization, new applied fluids and further development directions are emerging.
