Introduction |
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 Cocer a Wide application in auto mobile,motor damper and oilpumps,etc. |

Application |
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,motordamper and oil pumps etc. |
