SF-1S Self
Lubricating Bushing
is of oil resistant , acid resistant, alkali-resistant and seawater
resistant. Moreover, there is no lead in the PTFE surface layer, and so is
particularly fit for bushing in foodstuff machines, alkali flow meters,
pumps motion elements in pharmaceutical machines, printing machines chemical
engineering machines and other ocean industry. This is a triple layers
composites bush, the base material being a bronze plate and film of heat
resistant power filled PTFE being calendered onto the sintered spherical
bronze interlayer.

Size Specification
Application Case |
1. PTFE with oil
fibre can protect the shaft while machine in operation.
2. It is of low friction coefficient, good anti-wear.
3. Good running in property.
4. It fits well in motion of circumrotation, sway and to-and-fro.
5. Good anti-corrosion.
6. It can be used in food machine, Pharmaceutical machine etc. due t
lead-free.
7. Besides the same function of SF-1P, SF-1D in particular fits frequently
reciprocating motion with a high side force, it is widely used in
automobile, motor damper and oil pump etc. |
