Metal-polymer composite bearing with POM material (DX bushing)

1.Part name: SF-2 bushing
2.Material:Steel backing + Sintered bronze + PTFE
3.Appearance:Tin or Copper plated

Boundary Lubrication Bushing SF-2 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.

SF-2 It made of high quality low carbon steel backing with sintering porous bronze in the interlayer and rolled POM&PB compound on the surface. It can offer the good load capacity and wear-resistant. The product is applied to vehicle chassis, forging and pressing machine, metallurgical machinery, and hydraulic industry and rolling steel industry and so on.

SF-2H It made of high quality low carbon steel backing with sintering porous bronze in the interlayer and rolled POM compound on the surface. It can offer the good load capacity and wear-resistant. The product is applied to vehicle chassis, forging and pressing machine, metallurgical machinery, and hydraulic industry and rolling steel industry and so on.

SF-2S
SF-2L It made of high quality low carbon steel backing with sintering porous bronze in the interlayer and rolled POM compound on the surface. It can offer the good load capacity and wear-resistant. The product is applied to vehicle chassis, forging and pressing machine, metallurgical machinery, and hydraulic industry and rolling steel industry and so on. SF-2L is with blue PTFE and SF-2S is with orange PTFE.
