Loads

Minimum load

For additional information
Requisite minimum load
Frm = 0,02 C

Except for SKF Explorer bearings:
Frm = 0,017 C

Perform calculations
Equivalent dynamic bearing load

For additional information
Equivalent dynamic bearing load, P
Face-to-face or back-to-back arrangement

Fa/Fr ≤ e
→ P = Fr + Y1 Fa

Fa/Fr > e
→ P = 0,67 Fr + Y2 Fa

Tandem arrangement1)

Fa/Fr ≤ e
→ P = Fr

Fa/Fr > e
→ P = 0,4 Fr + Y Fa
Perform calculations
Equivalent static bearing load

For additional information
Equivalent static load
Face-to-face or back-to-back arrangement

P0 = Fr + Y0 Fa

Tandem arrangement1)

P0 = 0,5 Fr + Y0 Fa

1) When determining the axial load Fa, refer to Calculating the axial load for bearings mounted singly or paired in tandem.
