PVB-010 Steel back self-lubricating bush (du bushing)
| PVB010 | Characteristics: |
Good wear and friction performance over a wide range of
loads,speeds and temperature without oil | |
| 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. | |
Availability: | |
?Standard cylindrical bushing, flanged bush,thrust washers and
strips are availabe | |
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. | |
