Material use and installation method of FAG imported bearings
Quality control of both bearing manufacturing and steel quality is a guarantee of product quality stability.
FAG imported bearings http://www.skf-fag-nskcn.com are made of alloyed alloy steel or carbon steel refined by electric furnace. The steel used for FAG bearings is basically low carbon carburized steel. However, there are special cases where high carbon high quality bearing steel which is case hardened or hardened is required. Due to the different bearing sizes produced, it is necessary to add an appropriate amount of alloying elements in the molten steel to ensure the best performance of the finished product.
When using low carbon steel, after machining, carbon will penetrate into the surface of the bearing component, which is deep enough to form a hardened outer shell to withstand the bearing load. This carbon and early alloying elements ensure hard and fatigue resistant. The perfect combination of exterior and sturdy and soft core. High carbon steel does not require carburization and can be surface hardened, usually by induction heat treatment, or hardened by conventional methods.
Another advantage of tapered carburized steel for surface carburized steel is the residual compressive stress in the surface layer. These compressive stresses delay the expansion of fatigue cracks near the bearing raceway and roller surface, and increase the bending at the large rib groove. Fatigue strength. The robust and tough shaft core of FAG's imported bearings uses bearings to increase the ability to withstand heavy loads without damage. FAG Imports has conducted extensive research on the performance and life of bearings in the company to determine the optimum combination of optimum steel composition and heat treatment.
Bearings used under normal operating conditions can be used in the following situations:
1. The maximum temperature of 12 ° C to 150 ° C allows the temperature to be temporarily increased to 175 ° C.
2. The lowest ambient temperature is about -50 °C.
3. The highest Hertz contact pressure is 2100 to 3100 MPa.
