4.8 Permissible Static Tilting Moment
In case of static load, the bearing load capacity can be determined as follows:
Equation 45.1
and so

4.9 Angle of Inclination
The angle of inclination of the output flange, as a function of the tilting moment acting on the output bearing, can be
calculated by means of equation 45.4:
Equation 45.4
with:
y [arcmin] = Angle of inclination of the output flange
M [Nm] = Tilting moment acting on the output bearing
K
[Nm/arcmin] = Moment stiffness of the output bearing (table 23.1)
