The transmittable torques of the clamping connection consider the max. clearance with bore H7/k6 shaft fit.
The torque is reduced in case of bigger fit clearance.

ATTENTION!
For the applications in hazardous areas the setscrews to fasten the
hubs as well as all screw connections have to be secured against
self-slackening additionally, e. g. by glueing with Loctite (medium-
tight).
!
CAUTION!
An calculation is necessary if
hollow shafts are used!

The transmittable torques of the clamping connection consider the max. clearance with bore H7/k6 shaft fit.
The torque is reduced in case of bigger fit clearance.
1)
ATTENTION!
For the applications in hazardous areas the setscrews to fasten the
hubs as well as all screw connections have to be secured against self-
slackening additionally, e. g. by glueing with Loctite (medium-tight). !
CAUTION!
An calculation is necessary if
hollow shafts are used!
