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 machine shaft.
First fit machine shaft. Then tighten the clamping bolts.
NOTICE
Avoid overloading the individual bolts
Do not exceed the maximum tightening torque for the clamping bolt.
Sizes 19 - 69:
tighten clamping bolts ⑥
Sizes 79 - 89:
it is important that the face surfaces of the outer ring ④ and the inner ring ⑤ are flush with
one another. If they are not flush with one another when tensioning, check the tolerance of
the plug-in shaft.
Note
The shrink disk, item ③, is delivered ready for installation.
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
Note
The shrink-fitted disc connection fastens the hollow shaft axially on the machine shaft.
Note
Apply a thin layer of grease to the shrink disk seat on the hollow shaft.
