Composite bearings are used in a wide variety of applications. They are divided into many materials and different materials are used in different places.
The morning composite bearing mainly has the following materials:
Model: CHB-1
Modified polytetrafluoroethylene (PTFE) and lead (Pb) mixture 0.01 ~ 0.03mm, a wear-resistant material, can form a transfer film during operation to protect the grinding shaft.
The copper powder layer 0.2-0.3mm improves the bonding strength of PTFE/Pb and steel plate, and has good bearing capacity and wear resistance. At the same time, copper is a good thermal conductive material that can quickly transfer the heat generated during the operation of the bearing.
Low carbon steel 0.7 ~ 2.3, improve bearing capacity and heat transfer.
Copper/tin plating, copper plating 0.008mm, tin plating 0.005mm, makes the bearing have good corrosion resistance.
Application features: Suitable for working without oil. The static friction coefficient is close, which can prevent the "crawling" phenomenon. Wide temperature range, can work in the temperature range of -195 ° C ~ +270 ° C. Good wear resistance, low friction coefficient and long service life. It has good corrosion resistance and can work in a variety of corrosive media including liquids and gases. High mechanical strength, can withstand large stable loads and dynamic loads. It can reduce vibration, reduce noise and improve working environment.
Model: CHB-2
1. The mixture of modified polyoxymethylene (POM) and lead is 0.3-0.5mm, which has high wear resistance and low friction coefficient even in the case of instantaneous oil shortage. The surface of the bearing has a regularly arranged oil storage pit with a spiral angle. When assembling, it must be coated with lubricating grease.
2. The copper powder layer is 0.2-0.3mm, which has good load-bearing capacity and wear resistance. Good thermal conductivity can transfer the heat generated during the operation of the bearing. The composite material can penetrate into the gap of the copper powder ball to improve the bonding strength.
3. Low carbon steel 0.4~2.2mm, improve the bearing capacity and heat transfer of the bearing.
4. Copper/tin plating layer, copper plating layer 0.005mm, tin plating layer 0.002mm, tin plating layer has anti-rust function.
Application features: It is suitable for low-speed medium-loaded places under normal temperature conditions, replacing traditional copper sleeves, reducing costs and extending service life. In special cases, it can be used on the rolling mill to save fueling frequency and simplify the replacement procedure. This product has been widely used in automotive chassis, forging machine tools, metal mining machinery, engineering machinery, hydropower, steel rolling industry and other fields.
