Pvb-010 steel back self-lubricating bush (du bushing) Structure: 1.Ptfe/pb 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 availabe Lead free type is also available All special designs are produced according to your requirement Applications: Lifting equipment, hydraulics and valves, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, construction equipment, meterial handing equipment, packaging equipment, automotive field, scientific equipment, drying ovens, office equipment, etc.
