Equivalent dynamic bearing load
When double row cylindrical roller bearings are used as non-locating bearings
If cylindrical roller bearings of the NNUP design with flanges on both inner and outer rings are used to locate a shaft in one or both directions, the equivalent dynamic bearing load should be calculated using
|when Fa/Fr ≤ 0,1|
|when Fa/Fr > 0,1|
Since axially loaded cylindrical roller bearings will only operate satisfactorily when they are subjected to a simultaneously acting radial load, the ratio Fa/Fr should never exceed 0,25.
