Hydrostatic bearings can achieve no direct contact between metals, so as to achieve pure liquid friction and reduce friction between them. Servo cylinder guide sleeves can use static pressure support to reduce friction and increase cylinder life. However, in special conditions, the hydraulic cylinders are often subjected to radial eccentric load, and the oil film properties of the new asymmetric hydrostatic support structure are studied. Fluent software was used to simulate the flow field of the traditional four pad hydrostatic bearing and the new asymmetrical hydrostatic bearing structure respectively to compare the distribution of pressure cloud and the changes of friction at different inlet pressures, different piston rod speeds, and different eccentricities. By analyzing the pressure cloud diagram, the bearing performance of two different hydrostatic support structures was compared. The simulation results show that the friction force of the new asymmetric hydrostatic support structure is small, and it can be selfadaptive balanced when the piston rod is subjected to radial eccentric load.
