Note: Series products can also choose different base materials according to different working conditions.

Application

Pedal assembly, balance bushing, brake caliper, steering pin bushing and truck tail bushing

Chemical properties

CHB-2Y HXOB-20 The surface polymer is resistant to chemical corrosion, so its corrosion resistance is mainly determined by the steel back and the surface plating layer.

Abrasion resistance

The wear characteristics under grease lubrication conditions are as follows: its "run-in" wear rate is small; it can be seen from the figure that when the grease applied during assembly is consumed to a certain degree, its wear rate gradually increases

The main factors affecting life

1) Influence of PV value
PV value is an effective index to determine the wear life of CHB-1. If longer life is required, the PV value must be reduced.
2) Influence of ambient temperature
The higher the ambient temperature, the shorter the service life of CHB-2Y 3) Impact on the pieces
When the counterpart uses an alloy steel or hard chrome-plated shaft, the surface roughness Ra = 0.4 ~ 0.63, the service life of CHB-2Y bearings can be significantly improved.
In addition to the standard products shown in the catalog, non-standard products can also be provided or ordered according to customer requirements.
