4.3 Installing a load
When installing a load on the motor (gearhead), pay attention to the following points.
•
Align the centerline of the motor output shaft (gearhead output shaft) with the centerline of the load.
•
A key slot is provided on the output shaft of each combination type parallel shaft gearhead.
Form a key slot on the load side and secure the load using the supplied parallel key.
Note
•
When coupling the motor (gearhead) with a load, pay attention to centering, belt tension,
parallelism of pulleys, etc. Also, rmly secure the tightening screws of the coupling or pulleys.
•
When installing a load, do not damage the motor output shaft (gearhead output shaft) or
bearing. Forcing in the load by driving it with a hammer, etc., may break the bearing. Do not
apply any excessive force to the output shaft.
•
Do not modify or machine the motor (gearhead) output shaft. The bearing may be damaged or
motor (gearhead) may break.
•
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of the output shaft as an auxiliary means for preventing the transfer mechanism
from disengaging.

4.4 Permissible radial load and permissible axial load
The radial load and the axial load on the output shaft of the motor (gearhead) must be kept under the permissible
values listed below.
Note
Failure due to fatigue may occur when the motor (gearhead) bearings and output shaft are subject
to repeated loading by a radial or axial load that is in excess of the permissible limit.

Minimize the axial load. If an axial load must be applied, do not let it exceed one-
half the motor’s mass.
