Self-Lubrication Gear Oil Pump Bushing (Split Plain Bearing)

Gear oil pump bushes.

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

Introduction: 
Gear oil pump bushing is a new kind of GFB-1 which composes of a specially designed surface layer of PTFE formulations and is specifically applied for the high PV bushes of gear oil pumps.

Gear oil pump bushing is to be used in hydrodynamic or boundary lubricating condition of medium or high pressure gear oil pumps such as P=16-25Mpa, V= 3.5-5m/s. It shows the benefit of low friction coefficient, wear resistant and anti-impact properties. At hydrodynamic lubrication, the PV limit reaches to 120N/mm2@m/s. It is a best choice for various kinds of gear pumps as well as plunger pumps, vane pumps and so on.

Technical: 
Load capacity: 140N/mm2 
Temperature: -195~+280° C 
Speed limit: 10m/s 
Friction coef(u): 0.03~0.18 
PV LIMIT(Dry): 4.3N/mm2. M/s 
PV LIMIT(OIL): 60N/mm2. M/s

Application: 
1. Low friction under oil condition. 
2. Wear resistant and anti-impact. 
3. At hydrodynamic lubrication, the PV limit reaches to 120N/(mm*mm)*m/s. 
4. It is the best choice for the bushes in various kinds of gear pumps 
As well as plunger, vane pumps and so on.
