Introduction: |
SF-1W is a new type
bushing without lead composition which is developed aiming at increasing demands
on environmental protection.Besides its wide application on general
machines,SF-1X is particularly suitable for food machine,Pharmaceutical
machine,tobacco,machine etc.
|

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
