First, Talk about rolling bearing vibration type, inside and outside the ring and rolling element of the rolling bearing vibration type vacuum degassed bearing steel, good fatigue resistance. Aluminum iron and manganese bronze material, high strength, good elasticity, wear resistance and the cage better.
   
Second, And then look at Rolling ordinary type, Rolling common type of inside and outside the ring and rolling element common bearing steel. There is a cage with zinc brass, low strength, poor flexibility.
   
So, how to choose a common type of rolling bearing vibration type or Rolling it? , The following three o'clock available for reference:
   
1. fixed load, fixed-load characteristics of the synthetic radial load vector and the ring is relatively static.
   
2.The two rotating load, rotating the load characteristics of the synthetic radial load vector relative to the ferrule rotation.
   
3. swing load and uncertain loads, swing loads the rotating load is much smaller than the fixed load and synthetic load. Swing load suffered loads of some rings may sometimes rotating load, sometimes a fixed load, sometimes swinging load.
   
In general, the vibration type of rolling bearing ring and shaft or housing bore, transition fit or interference fit, size of the interference to Rolling work load, the rolling bearing ring on the shaft or seat hole with the surface does not produce the phenomenon of "creep" as the principle.
