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 tendency to gradually replace SF-1P
with SF-1D, the latter will cover a wide application in automobile, motor
damper and oil pumps, etc. ¡¡ |

Application |
¡¡ |
| 1. PTFE and lead
can protect the shaft while the machine in operation. 2. Bronze have good thermal conductivity, it'll divert heat while the machine operating. 3. It can be applied in the machine, working long time, which examine and repair is incapable, because the bronze can lubricate itself. 4. It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing. 5. Good load capacity 6. It is widely used in steel metallurgy industry, such as bushed for filler grooves of successive casting machines, cement grouting pumps and screw conveyers of machine etc. 7. It can be composed in steel housing , or fabricated into flange bushes which result in function for motion both on flange and I.D. |

Size Specification    Application Case |
| 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 t 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, motor damper and oil pump etc. |
