Equivalent Dynamic Load-Thrust Ball Bearings

The equivalent dynamic load of thrust ball bearings can be calculated from:

α= 90° P = Fa

α≠ 90° P = XFr + YFa

Single Direction Bearing:

When α= 45°

Fa/Fr>e X = 0.66 Y =1 e = 1.25

When α= 60°

Fa/Fr>e X = 0.92 Y =1 e = 2.17

Double-Direction Bearing

When α= 45°

Fa/Fr>e X = 0.66 Y = 1 e = 1.25

Fa/Fr≤e X = 1.18 Y = 0.59 e = 1.25

When α= 60°

Fa/Fr>e X = 0.92 Y = 1 e = 1.25

Fa/Fr≤e X = 1.9 Y = 0.55 e = 2.17
