                 Abstract: The structure design of water-lubricated bearings has a significant influence on their friction and wear
                 performances, as well as lubricity. A new type of bionic water-lubricated bearing has been designed in order to improve
                 its tribological properties. There were Nepenthes Alata structures on its bearing bush, which were mainly two types:
                 crescent textures on the surface of slippery zones and ridged textures on that of the peristome. The flow field analysis
                 was carried out by ANSYS Fluent used the simplified lubricating film model of the bearing. By the variation of
                 rotational speeds, loads and surface textures of different shapes and sizes, the optimization of the anti-friction
                 performance and the load-bearing capacity of water film were explored and the mechanism was analyzed. It was found
                 that the crescent texture of CC1006 and the ridged texture of DR0102 had the best comprehensive optimization of anti-
                 friction performance and load-bearing capacity of water film respectively by comparing the maximum pressure and load-
