Recently, as for the rod guide bush bearing materials for shock absorbers, lower friction and the improvement of durability are required along with ride quality and longer life of automobile. Usually, lead is contained in bearing materials. However, the addition of the lead in bearing material is being restricted from the earth environmental problem. Bearing materials for shock absorbers are composite material consists of steel backing and covered with polymer surface layer. This basic material structure hasn't been changed till now, though it has been improved by changing its components and compositions based on the customer's requirement. Bearing material with both lower friction and excellent wear resistance has been developed in this study.
