Chemical properties

CHB-2 The surface polymer is resistant to chemical corrosion and can effectively prevent atmospheric corrosion.

Abrasion resistance

1)Running-in" phase: the surface layer of PTFE mixture wears the material faster. As shown by the curve I in the figure.
2） "Stable" wear stage: The friction after running-in becomes friction between PTFE, as shown by the curve in zone II in the figure.
3）"Absolute" wear stage: PTFE lubricant in the pores of the porous layer is consumed until the 70% bronze is exposed and the CHB-1 life is nearing its end. As shown in the III curve in the figure.

The main factors affecting life

1) Influence of PV value
PV value is an effective indicator for determining the life of CHB-1. It is required to extend the life, and the PV value must be reduced.
2) Influence of ambient temperature
The higher the ambient temperature, the shorter the service life of CHB-1.。 3) Impact on the pieces
When the roughness of the shaft used by the counterpart is within the range of 0.4 ~ 0.63, the service life of the CHB-1 bearing can be significantly improved.
In addition to the standard products in the catalog, customers can also be ordered on request.
