Analysis of the difference between the same point of the SKF bearing vibration type and the common type

Different points of the same point analysis First, let me talk about the SKF bearing vibration type, SKF bearing vibration type inner and outer ring and rolling element using vacuum degassing bearing steel, good fatigue resistance. Moreover, the cage is made of aluminum-iron-manganese bronze material, which has high strength, good elasticity and better wear resistance.

Second, let's look at the ordinary type of SKF bearing. The inner and outer rings and rolling elements of the SKF bearing are of ordinary bearing steel. There is also a cage made of zinc brass, which has low strength and poor elasticity.

So, how to choose SKF bearing vibration type or SKF bearing common type? The following three points are available for reference:

1 Fixed load, fixed load is characterized by a synthetic radial load vector and the ferrule is relatively stationary.

2 Rotating load, the characteristic of the rotating load is that the synthetic radial load vector rotates relative to the ferrule.

3 oscillating load and variable load, oscillating load is the load that is synthesized by rotating load much smaller than fixed load. The oscillating load means that the load on the ferrule may be a rotating load, sometimes a fixed load, and sometimes a oscillating load.

In general, the ferrules of the vibrating SKF bearing and the shaft or the seat hole require a certain transition fit or interference fit. When the SKF bearing is under load, the SKF bearing ring is on the shaft or seat. The principle of “creeping” does not occur on the mating surface in the hole.
