Mounting the drive in the tube
For profile shafts:
In the case of some drive adapters, tolerances of the groove widths in different barrels can be offset by
rotating the drive adapter into a different groove recess. These groove recesses have different sizes
and allow the drive to fit exactly.

For round shafts:
Measure the lug of the thrust ring (X, Y). Then notch the tube on the motor side, so the lug of the thrust
ring can also be pushed into the shaft. There must be no play between the lug of the thrust ring and the
shaft.
-10 mm
To ensure secure torque transmission for round shafts , we recommend screwing the drive adapter to
the shaft (see the table below).
Attention! When drilling into the barrel, never drill near the tubular drive!

be secured using springs or rigid shaft connectors. We recommend at least three pieces
per metre of barrel.
