SF-1D Corrosion Resistant Industrial Hydraulic Oilless Bearing | High Load, Low Friction, Durable

Product Description:

SF-1D Hydraulic bearing 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, its 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 dampers,s and oil pumps, etc.
