It is particularly used in gear box for automobiles, generators, lifters, cranes and machines for metallurgical industry.

SF-1D hydraulic bushing is developed on the basis of SF-1P and meanwhile considering the working principle of oil pump and damper.It shows better performance under working condition of without oil lubrication.It is the substitution of and parallels in performance with DP4 type product abroad.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. Load capacity:140N/mm2 Temperature:-195~+280°C Speed limit:3m/s Friction coef(μ):0.04~0.20 PV limit(dry):3.8N/ mm2.m/s PV limit(oil):50N/ mm2.m/s
