SF-1P RECIPROCATING MOTION BUSHING

Structure



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
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.
