Equivalent dynamic bearing load

The equivalent dynamic bearing load can be determined as follows:

For single bearings and bearings arranged in tandem

Perform calculation

For bearing pairs, arranged back-to-back or face-to-face

Perform calculation

The values for the factors e, X2, Y1 and Y2 depend on the bearing contact angle and are listed for:
  • single bearings and bearings arranged in tandem (table 1)
  • bearings paired back-to-back and face-to-face (table 2)

For bearings with a 15° contact angle, the factors e, Y1 and Y2 depend on the relationship f0 Fa/C0

where


P=equivalent dynamic load on the bearing set [kN]
Fr=radial load acting on the bearing set [kN]
Fa=axial load acting on the bearing set [kN]
f0=calculation factor (→ product table)
C0=basic static load rating [kN] (→ product table)
