CHB-1D Hydraulic special bearings
CHB-1D Hydraulic special bearing. It is a new material designed on the basis of CHB-1P in combination with the working principle of the oil cylinder and shock absorber. It is especially suitable for high-reciprocity occasions with frequent reciprocations. Its performance is similar to foreign DP4. At present, this product gradually replaces CHB-1P products.

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

Blindly choose lubricants: Lubricants act to lubricate, cool, clean and seal. The quality of the lubricant is directly related to the length of the engine life. Blackening of the engine oil is the deterioration of the engine oil
Answer: 1) Metal materials, such as high-strength brass, tin bronze inlaid graphite bearings, etc. 2) Porous metal material (powder metallurgical material). 3) Non-metallic materials (nylon, polytetrafluoroethylene).
Answer: Oil-free lubrication bearings are a type of plain bearings. Generally, the sliding bearing needs to add lubricants such as lubricating oil and grease before working, so as to form a lubricating film on the friction surface to effectively lubricate
Main Products: Copper sleeve, graphite copper sleeve, self-lubricating copper sleeve, sliding bearing, composite bushing
