After the rolling process is completed, PTFE mixtures are filled in the interstice of the bronze layer. Under normal operation, Part of the PTFE mixture on the top layer will be removed and transferred to the mating surface, forming a physically lubricating film, which will reduce the friction cone. and protect the mating shaft.

Self-lubricating bearing
metal composite self-lubricating material with high-quality low carbon steel as the substrate, the middle spherical sintered porous copper powder layer, the surface tie with PTFE wear-resistant lubricating material as bearing working layer, this material has excellent mechanical load capacity , The middle layer of copper powder not only in time to pass bearing the heat generated during operation, but also improves the plastic layer and substrate bonding strength. PTFE is designed for complete dry friction and has developed a wide range of materials based on lubrication, friction coefficient and durability requirements. Bronzelube.com PTFE metal composite materials in the external lubrication or non-lubricating circumstances, can in the most extensive load, speed and temperature range to provide the best performance.
PTFE composite thrust washers are self-lubricating as well as maintenance-free and provide a long service life due to low friction. Despite their compact design, these washers can accommodate heavy axial loads and are suitable for relatively slow rotational or oscillating movements. They also have good dimensional stability and thermal conductivity.
PTFE composite washers consist of a sheet steel backing on which a 0,2 to 0,4 mm thick porous layer of tin/bronze is sintered. Furthermore, by a rolling process, the pores of the sintered layer are filled with a mixture of PTFE (polytetrafluoroethylene) and molybdenum disulfide additives. This additional 5 to 30 μm thick running-in layer provides an optimum combination of the mechanical properties of the sintered tin/bronze and the good sliding and lubricating properties of the PTFE mixture.
Running-in period
During a short running-in period, minute amounts of the PTFE material from the running-in layer are transferred to the counter surfaces. After this transfer has taken place, the characteristics of low friction and wear properties of these washers are reached.

Carbon Steel + Copper Powder + (PTFE + Pb + Filler)
Steel backed with copper-plated steel with porous bronze sintered on the steel and polymers (PTFE+Pb) embedded into the bores of the bronze. By combining the metals and the polymers together, its products are endowed with a lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with an erosion-prevention layer. Products of the PTFE composite series are widely applied in printing, weaving, and tobacco-producing machines, gymnastic equipment, etc.

Self-Lubricating Multilayer Composite Bushing is of excellent anti-abrasion performance, mainly due to the particular molecule structure of PTFE. The abrasion process can be generally divided into three phases, so there are kinds of friction coefficients. See the right graph:
1. “Running-in” phrase: PTFE compound on the bushing is transferred to its mating surface and forms a lubricating film. At this phase, the friction coefficient is bigger, thus the abrasion pace is very quick. See the curve shown in area I of the graph.
2. “Stabilization” abrasion phrase: After the “Running-in phase”, the friction happens between PTFE and PTFE, thus the friction coefficient is smaller and keeps steady. As a result, the wear rate is low and steady. See the curve shown in areaⅡof the graph.
3. “Sharp” abrasion phrase: As PTFE in the porous layer is slowly consumed up, not enough lubricant can be supplied to the gliding media. The friction coefficient and wear rate will rapidly rise. When 70% of the bronze surface is exposed, the service life of Self-Lubricating Multilayer Composite Bushing closes to its end. See the curve shown in area Ⅲof the graph.
