The transmittable torques of the clamping connection take into account the max. fitting tolerance for shaft clearance k6/bore H7,
from Ø 55 G7/m6. With a higher fitting tolerance the torque is reduced.

P R E C A U T I O N !
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).
!
C A U T I O N !
An calculation is necessary if
hollow shafts are used!
