Product Description

 

Oiless Composite Bushes , Self Lubricating Bushing SF-1P, for Hydraulic Cylinders

 

 

Description:

  • SF 1P is particularly suitable for bushes in reciprocating motion.
  • 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.
  • 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.
