Rated dynamic load of bearings

Time：

Aug 20,2022

The rated dynamic load is to compare the bearing capacity of the bearing against pitting corrosion. When the rated life of the bearing is stipulated to be one million revolutions (106), the maximum load it can bear is the basic rated dynamic load, expressed in C.

That is, under the action of rated dynamic load C, the reliability of this bearing working for one million turns (106) without pitting failure is 90%, and the greater the C is, the higher the bearing capacity is.

For basic dynamic load rating

1. Radial bearings refer to pure radial loads

2. Thrust ball bearing refers to pure axial load

3. Radial thrust bearing refers to the radial component generated by pure radial displacement
