| Application |
1.PTFE and fibre can protect the shaft while in operation.
2.It is suitable for the machine required harmless to people because
of Lead-free.
3.Goodload capacity and anti-wear.
4.Bronze and steel have good thermal conductivity.
5.Anti-corrosion because of surface plating.
6.It is widely used in general machines,and suitable for food machine,pharmaceutical
machine,tobacco machine etc.It will subsitute SF-1 in future because of environment protection. |
