    SF-1 Plain Steel Bushing

     

    SF-1 Plain steel bushing is a type of DU bushing. It's also called Teflon bearing, DU bush and PTFE lined dry sliding bearing, SF-1 bearing, and oil free bushes. SF-1 self-lubricating bearing has a common structure with other DU bearing.

    Material structure:

     

    1. PTFE / Pb or fiber mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.

    2. Porous bronze 0.2~0.3mm provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.

    3. Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.

    4. Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.

    Characteristics:

    · Good wear and friction performance over a wide range of loads, speeds and temperature without oil

    · Also perform well with lubrication

    Maintenance-free, long life

    Availability:

    · Standard cylindrical bushing, flanged bush, thrust washers and strips are available.

    · Lead free type is also available

    · All special designs are produced according to your requirement

    Applications:

    PVB010 DU bearing is widely used in Lifting equipment, Hydraulics and valves, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, construction equipment, material handing equipment, packaging equipment, automotive field, scientific equipment, drying ovens, office equipment, etc.
