3.4.4 Axial force diagrams
The maximum axial forces F
A
as a function of the radial force (cantilever force) are shown in
the following force diagrams. The permissible bearing forces are specified without taking into
account the force due to spring-loaded bearings, the rotor weight for vertical mounting as
well as the direction of the force.
