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.
