dial_max
The maximum allowed radial force F
radial_max
depends on the following factors:
● Shaft break load
● Point of application of force x
● Shaft design (plain [1]; with keyway [2])
Allowed radial force F

depends on the following factors:
● Arithmetic mean speed (n

● Point of application of force x
● Bearing service life

is specified in the technical data.
Average speed
The run-up and braking times can be ignored in the calculation, if the time in
which the drive is operated at a constant speed is significantly greater than
the acceleration and braking time. In the exact calculation of the average
speed according to the following example, the run-up and braking times are
taken into account.
