Company Introduction:
Features :
Carbon steel bearings are characterized by low price, the use of bearing requirements are not too high. Hardness, wear resistance, life and so on are worse than conventional bearing steel bearings.
Carbon steel bearing performance description:
First, carbon steel bearings in terms of service life. Their service life is very different, the service life of bearing steel is long, many garbage bearings are carbon steel bearings, mainly hardness and wear resistance are not as good as bearing steel bearings.
Second, in wear resistance. Low carbon steel only in the surface carburizing surface quenching, and not all quenched. Many low-grade carbon steel bearings on the market are not hardened at all, and their wear resistance is very poor.
Third, in the process and use effect. Bearing use effect is related to the use of the environment, not to say that carbon steel bearings are not good, it depends on which machinery to use, because some do not need high-grade, with carbon steel bearings is appropriate. Of course, Luo Steel is better but the cost is much higher. The standard bearing steel is Gcr15.
Fourth, in bearing materials and performance. For example, the bearing ring and the rolling body should repeatedly withstand high contact pressure, and carry out rolling contact with sliding, while maintaining high precision rotation. Therefore, whether the material and performance of bearing ring, rolling body and cage meet the following requirements: high elastic limit; High rolling fatigue strength; To have a high hardness; Good wear resistance; Good toughness against impact load; Good dimensional stability. In addition, but also good processing. It has been proved that bearing steel has the properties required above, but carbon steel bearings cannot be guaranteed.
Fifth, it is not that the advantages of carbon steel bearings are not good enough for bearing steel to be available, it depends on where to use. Carbon steel bearing noise, life is very short, the pressure is very small, but can be used in hardness, limit speed is relatively small.
Surface strengthening technology can be classified into five categories: surface deformation strengthening, surface heat treatment strengthening, chemical heat treatment strengthening, surface metallurgy strengthening and surface film strengthening according to the physical and chemical process of surface strengthening technology.
