Alignment
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or risk of damage to the coupling.
The fitting misalignment must not be beyond the permissible range. It is however recommended to align
the coupling as precisely as possible so as to have an additional margin for misalignment in operation.

FLUDEX couplings in combination with the flexible NEUPEX addon coupling absorb positional
deviations of the shaft ends to be connected up to the values shown in item 6.5. When aligning, the radial
and angular misalignment of the shaft ends must be kept as small as possible, because, other conditions
being equal, this increases the service life of the flexible elements.
Alignment has to be done in two axial planes arranged perpendicularly to each other. This can be done by
means of a ruler (radial misalignment) and feeler gauge (angular misalignment), as shown in the
illustration. Coupling gap "S" should be adhered to (see item 6.5.4).
The aligning accuracy can be increased by using a dial gauge.
To allow the shaft end to rotate freely, the drive train can be disconnected by releasing the screw
connection, parts 2/3, and pulling part 3 back out of the sockets of the NEUPEX coupling.
After rejoining the connection the tightening torque of the bolts (13) must be checked (see item 6.6).
The alignment must be checked once more with the foundation bolts of the motor and gear unit/driven
machine tightened. Any shaft misalignment through heating during operation must be taken into account.
