Equivalent dynamic load-Deep Groove Ball Bearings

Equivalent dynamic load of deep groove ball bearings is not only dependant on the ratio of the axial load and the basic static load rating, but, are also influenced by the magnitude of the radial internal clearance. Increased radial clearance enables axial load carrying capacity to be higher. The equivalent dynamic load of deep groove ball bearings can be calculated as follows :

Fa / Fr ≤e， P = Fr

Fa / Fr >e， P = X·Fr + Y·Fa

where：

P — equivalent dynamic loading ，N

Fa — Axial loading ，N

Fr — radial loading ，N

X — radial loading coefficient

Y — Axial loading coefficient

Coefficient e，X,Y have been listed in the following sheet.
