Material Features:

SF-1D Hydraulic bushing is developed on the basis of SF-1P and meanwhile considering the motion way of oil pump and damper. It is the substitute of and parallels in performance with abroad DP4. In addition to covering the same usage of SF-1P, SF-1D in particular fits frequently reciprocating motion with a high side force. It is a tendency to gradually replace SF-1P with SF-1D, the latter will cover a wide application in automobile, motor damper and oil pumps, etc.

 

Application Feature:

1.PTFE with oil fibre can protect the shaft, while machine in operation.

2.It is of low friction coefficient, anti-wear.
3.Good running in property.
4.It fits well in motion of circumrotation, sway and to-and-fro.

5.It can be used in food machine, pharmaceutical machine etc. due to lead- free.
6.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 pumps etc.
