We have been developing a micro reducer with small, high accuracy and low cost. This micro reducer is composed of plastic plain bearings and mold plastic gears with shaft. One of the problems in this R & D gear system is how to reduce friction and wear between mold plastic plain bearings and mold plastic plain shafts or metal plain shafts. We tried to solve this problem by the combination of materials and lubricants. The much longer Operating life of a micro reducer is inquired. We developed the micro reducer much longer operating life. In this paper, effects of lubricating grooves on the plastic bearings are examined, and much longer life for the micro reducer is described.
