Based on the Reynolds equation,a finite length non-eccentric radial sliding bearing hydrodynamic lubrication model was established. Three different kinds of single surface texture and three different mixed surface texture lubrication model were established. Programming with MATLAB,the performance of load carrying capacity of non-eccentric radial sliding bearing with different types and different area density of surface texture were respectively compared and analyzed.The results showed that compared with the single surface texture,the enhancement degree of load carrying capacity of mixed arrangement surface textures would depend on its arrangement type. Furthermore,it has been found that there were optimum parameters and arrangement type of surface texture of non-eccentric radial sliding bearing to reach the max maximum of load carrying capacity.
