Production Description:

WZB-1D hydraulic bushing is developed on the basis of SF-1P and meanwhile considering the motionway of oil pump and damper. It is the substitute of and parallels inperformance with abroad DP4. In addition to covering the same usage of SF-1P. SF-1Din particular fits frequently reciprocating motion with a high side force. Itis a tendency to gradually replace SF-1P with SF-1D, the latter will Cover a wideapplication in automobile, motor damper and oil pumps,etc.
