Wear

SF-20 has excellent abrasion resistance, which is mainly due to the special molecular structure of PTFE. SF-20 wear can be divided into three stages, corresponding to the coefficient of friction are also three cases, see illustration: 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, this time, the larger coefficient of friction, wear rate of the material faster. The Ⅰ curve shown.
2) "stability" wear stage: The friction fit after running into friction PTFE between its low and stable friction coefficient, low wear rate material smoothly. Curve shown in Figure Ⅱ area.
3) "sharp" wear stage: PTFE in the pores of the porous layer 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 also dramatically speed up until 70% bronze bare, SF-20 closer to terminate life. As shown in the graph shown Ⅲ

Effect of life

1) Effect of PV value
PV value is to determine the effective index SF-20 wear life.

2) Environmental temperature
The higher the ambient temperature, the shorter the life of SF-20 3) Effect of dual member
Dual use items or hard chrome plated steel shaft, surface roughness Ra = within the range of 0.4 to 0.63, SF-20 bearing life can be significantly improved.
