Hydraulic Cylinder Bearing LFB - 0306 Self Lubricating Bushing SF-1T for Gear Pump
Description:
SF 1T is composed of a specially designed surface layer of PTFE formulations and is specifically applied for the high PV bushes of gear oil pumps.
It is to be used in hydrodynamic or boundary lubricating condition of medium or high pressure gear oil pumps such as P=16-25 Mpa,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.
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:
