Manual – Gear Units and Gearmotors
Overhung and axial loads (→ GM, → MM, → GK)
Project Planning for Gear Units
Higher permitted
overhung loads
Exactly considering the force application angle α and the direction of rotation makes it
possible to achieve a higher overhung load. Higher output shaft loads are permitted if
heavy duty bearings are installed, especially with R, F and K gear units. Contact SEW-
EURODRIVE in such cases.
Definition of force
application point
Force application is defined according to the following figure:
Permitted axial
loads
If there is no overhung load, then an axial force F
A
(tension or compression) amounting
to 50 % of the overhung load given in the selection tables is permitted. This condition
applies to the following gearmotors:
• Helical gearmotors except for R..137... to R..167...
• Parallel shaft and helical-bevel gearmotors with solid shaft except for F97...
• Helical-worm gearmotors with solid shaft

Contact SEW-EURODRIVE for all other types of gear units and in the event of
significantly greater axial forces or combinations of overhung load and axial force.
