| Value Type | PMDouble |
The static axial factor Y0 is required to convert the axial force to an equal (equivalent) radial force.
The factor can be taken from the respective bearing catalog or determined according to ISO 76.

| Radial spherical roller bearings | 0.5 | 0.22 * cot(α0) | 1 | 0.44 * cot(α0) |
| Radial tapered roller bearings | 0.5 | 0.22 * cot(α0) | 1 | 0.44 * cot(α0) |
The factors are used to calculate the static equivalent bearing load P0.
P0 is the force which results in equal surface pressure in the center of the high-stress contact point between rolling element and raceway under defined load rating conditions.
