Possible Application

It is particularly suitable for bushes in reciprocating motion, and the surface layer is lately optimized formulation, and is efficient even under sudden break off of the lubricating oil. It is wear resistant, and so can keep the lubricating oil clear after long period of working. It can protect the mating metal surface from wearing, particularly suitable for reciprocating motion It is used widely as oil damping vibrating absorber of automobiles, motorcycles and various hydraulic cylinders, hydraulic motors and pneumatic elements
