Gear Pump Bearing , Bronze Self Lubricating Bushing SF-1T for hydraulic equipments

Description:

1. SF-1T bushing is specially designed for gear pumps.

2. It is made on the basis of SF-1X, suits for working condition of high PV value of gear pump.

3. It has good performance of anti-fatigue and anti-punching.

4. It shows the benefit of low friction coefficient, wear resistant and anti-impact properties.

5. At hydrodynamic lubrication, The PV limit reaches to 120N/mm2.m/S.

Fearture:

• Maintenance-free!
• No lubrication required (PTFE composite)
• Minimum wall thickness, minimum space requirements
•  Accommodation of heavy loads
• Wide range of temperatures
• Good sliding properties
•  High wear resistance

Structure:

1.PTFE with lead 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
