1.PTFE with CU 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm |
| Introduction |
| 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,and so 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 |
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. |
