Orange POM Boundary Lubricating Bearings , Marginal-Lubrication
SF-2 is triple-layer self-lubricating material that can fill
modified POM plastic as surface layer
1.Part name: SF-2X BUSHING
2.Material:Steel backing + Sintered bronze + PTFE
3.Appearance:Tin or Copper plated
Boundary Lubrication Bushing SF-2X is composed of three layers:
steel backing, sintered bronze
layer and modified POM layer. It fits well for low speed, high load
normal temperature occasions with rotational ,oscillating or
stop-start motion. It can works long time under boundary
lubrication circumstances, if oil or grease is added, its working
life can be prolonged further.
This kind of bushing can be applied in auto chassis, forging
machine, metallurgical machine, civil engineering, power station,
strip rolling industry etc.
