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
