By using pinondisk type friction pairs under fluid lubrication,friction experiments were carried out for the bearing steel with microcrosshatch grooved surface pattern at two different angles of 90° and 135°.The sliding directions of experiments were passed over the middle of angles of 45°,90° and135°separately.The Stribeck curves were used to analyze the friction characteristics of the surfaces with different angles of microcrosshatch grooved pattern under different test conditions.The friction coefficient graphs were used to analyze the friction properties of these microcrosshatch grooved surfaces.The results show that the friction coefficient is changed with changing of the surface pattern and sliding direction.The microgrooves have a considerable effect on friction reducing performance under the mixed and hydrodynamic lubrication condition,and friction coefficient produced by microgrooves and sliding directions is influenced by lubrication condition.The best friction reducing effect are obtained for the sample with microgroove surface pattern of 135° angle when testing at the sliding direction of passing over the middle of 135° angle
