SF-1T Gear Pump Bush

SF-1T Gear Pump Bush

Metallurgical

structure

1. PTFE/Pb Composition, 0.01-0.003mm, anti-abrasion material, which will form a lubricating film during operation.
2. Bronze powder layer, 0.2-0.35mm, which further strengthen the combination of the steel plate and PTFE layer and transfer the heat more quickly.
3. Low carbon steel, bear high load transfer heat.
4. Copper/Tin plating layer, anti-corrosion.

  TECHNICAL DATE

  APPLICATION CHARACTER

1.Low Friction under oiI condition
2.Wea r resistant and anti-impact．
3.At hydrodynamic lubrication，the PV limit reaches to 120N/mm2·m/s
4.It is the best choice for the bushes in various kinds of gea r pumps as well as plunger, vane pumps and so on.
