YLB-1D hydraulic bushings

Introduction
YLB-1D Hydraulic bushing is developed on the basis of YLB-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 YLB-1P,YLB-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 auto mobile motor damper and oil pumps, etc.

Metallurgical structure
1.PTFE with oil fibre 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm
Typical Application

Developed for high duty, oil lubricated, hydraulic applications...
Automotive suspension struts, shock absorbers guide bushing, hydraulic cylinders, gear pumps and motors and axial and radial piston pumps and motors. It is designed for use mainly under lubricated lubrications and shows excellent wear resistance, low static and dynamic friction coefficient.
