Equivalent Dynamic Load-Cylindrical Roller Bearings

For cylindrical roller bearings carrying dynamic loads, when applied as wandering end bearings, the equivalent dynamic load can be calculated as following :

P = Fr

If the bearing carries axial load in one direction or double directions,the equivalent dynamic load can be calculated from：

When Fa/Fr≤e P = Fr

When Fa/Fr>e P = 0.92Fr + Yfa

Where

e - Limiting value， For dimension series 2, 3, 4, e=0.2,

For other series e=0.3

Y - Axial load coefficient， For dimension series 2, 3, 4, Y=0.6, For other series Y=0.4

In order to obtain ideal effect, cylindrical roller bearing needs to carry axial load and radial load at the same time. However, the ratio of axial load and radial load should be smaller than 0.5.
