On the hydrodynamic slide bearing, friction force acting on the slider varies with the sliding speed and this is the main constraint for accurate positioning in slide bearing. In order to reduce the friction dependant on sliding speed under oil lubrication, the effect of various micro-patterns with different shapes or directionality on friction dependant on sliding speed. In addition, the effect of sliding speed on oil film thickness and pitching angle of slider were also observed. According to the friction test results, friction dependant on sliding velocity under hydrodynamic lubrication of oil was decreased with micro-patterns. And such effect was the most outstanding in the case of that micro-grooves were fabricated on the slider surface for the 45 degrees direction for sliding direction.
