1) "running-in" stage: PTFE surface layer of the mixture was transferred to the surface to fill the dual dual surface pits and form a lubricating film. 2) "stability" wear stage: The running-into frictional friction PTFE between its low and stable friction coefficient, low wear rate material smoothly. 3) "sharp" wear stage: the porous layer, the pores of the PTFE lubricant consumption, the interface can not be obtained between the friction sufficient amount of lubricant. Poor lubrication between the friction surfaces, a rapid increase in the coefficient of friction, wear rate has accelerated dramatically.
1) Effect of PV value: PV value is to determine the effective index SF-1 wear life. If you require longer life, PV values must be reduced.
2) Influence of ambient temperature: The higher the ambient temperature, the shorter the life of SF-1.
3) Effect of dual member: Duality pieces of alloy steel or hard chromium plated shafts, surface roughness Ra = within the range of 0.4 to 0.63, SF-1 bearing life can be significantly improved.
