Equivalent Dynamic Load-Thrust Roller Bearings

The equivalent dynamic load of thrust roller bearings can be calculated according to the following ：

α= 90°      P = Fa

α≠ 90°     P = XFr + YFa

Single Direction Bearing:

Fa/Fr＞e  X = tanα  Y = 1  e = 1.5tanα

Double-direction bearing

Fa/Fr≤e   X = 1.5tanα    Y = 0.67  e = 1.5tanα

Fa/Fr＞e   X = tanα      Y = 1    e = 1.5tanα
