摘　　要：Aiming at the new characteristic of water hydraulic system, a kind ofhydrostatic bearing with a concentric gap damper is introduced. The lubricative film thickness ofthe hydrostatic bearing possesses inflexibility and the loading capacity is just determined by thegeometrical dimension of the piston-slipper subassembly and has no relation with system pressure,viscosity and temperature of water and speed of rotor. Theoretical analyses and the verification ofscheme done at the test rig show that the hydrostatic bearing with a concentric gap damper isespecially fit for water hydraulic components.Aiming at the new characteristic of water hydraulic system, a kind ofhydrostatic bearing with a concentric gap damper is introduced.
