1.3.4 Alignment
In particular with direct coupling, the motor shafts and the driven machine must be axially and radially
aligned to each other. Incorrect alignment may result in damage to the bearings, excessive vibration
and breakage of the shaft.

1.3.5 Output shafts
The maximum permissible axial (F
A
) and radial forces (F
R
) for the A side end of the motor shaft can be
obtained from the table below. Getriebebau NORD should be consulted if the radial force (F
R
) is applied
at a distance which is greater than the length E/2.

) are permissible for the B side shaft end.
NOTICE! Attachments must not cause rubbing (danger of excessive temperatures and sparking) or
impair the necessary flow of cooling air.
