Mounting the shrink disk

Risk of injury due to freely rotating parts
Fit a cover cap or protection cover.
NOTICE
Lubricants in the shrink disk seat impair torque transmission
Keep the bore in the hollow shaft and the machine shaft completely grease-free.
Do not use impure solvents and soiled cleaning cloths.
NOTICE
Plastic deformation of the hollow shaft caused by tightening the clamping bolts
Plastic deformation of the hollow shaft when tightening the clamping bolts before fitting the

one another. If they are not flush with one another when fitting, check the tolerance of the plug-
in shaft.
Note
The shrink disk, item
Do not dismantle it before the initial fitting.
Note
The machine shaft material must comply with the following criteria in order to safely and reliably
transfer the forces and torques:
• Yield point Re ≥ 360 N/mm
• Modulus of elasticity: approx. 206 kN/mm
• No face end thread in the machine shaft because it would reduce the transferred torque
