SF-1P Reciprocate Self- lubricating Bearing
Material Features:
SF-1P is particularly suitable for bushes in reciprocating motion, and the properties are similar to that of the foreign product designated as DD2. It is wear resistant, so it can keep the lubricating oil clear after long period of working. Meanwhile it can protect the mating surface from wearing. It is used widely as oil damping vibrating absorber of automobiles, motorcycles and various hydraulic cylinders, hydraulic motors and pneumatic elements.
Application Feature:
1. It is efficient even under sudden break off the lubricating oil, wear resistant, and so can keep the lubricating oil clear after long period of working.
2. It can protect the mating surface from wearing.
3. It is particularly suitable for bushes in reciprocating motion.
4. It is suitable for the machine requiring harmless to people because of lead-free.
5. It is used in shock absorber of motorcycles and various hydraulic cylinders, hydraulic motors and pneumatic elements etc.
