Admissible forces on shaft extension
The values apply to the bearings and drive end shaft extensions
that are assigned in the following tables based on a calculated
service life of
L
10h
= 20000 h.
They are applicable for horizontal and vertical shafts.
F
Q
= Cantilever force in N
F
A
= Axial force in N
x
= Distance between point of application of force and
shoulder of shaft in mm
l
= Length of shaft extension in mm
