PTFE sleeve bearings is wall wrapped bearing made of triple layer composites material which consists of a steel backing,a sintered porous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer. PTFE is a popular self-lubricating bearing which is always applied to different kinds of machines.
1.It has good general applicability and can be applied to many kinds of machines.
2.It has no pollution,low noise but a long life.
3.The weight is very light.
4.PTFE and Lead filler is transferred to the mating shaft to improve running properties.
5.PTFE layer has good lubrication which can make machine work smoothly.
6.The price is very reasonable.
