Orange POM Boundary Lubricating Bearings , Marginal-Lubrication Bearing SF-2


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 frequent
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.
