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 tightening bolts
Plastic deformation of the hollow shaft when tightening the tightening bolts before fitting the
machine shaft.
First fit machine shaft. Then tighten the tightening bolts.
NOTICE
Avoid overloading the individual bolts
Do not exceed the maximum tightening torque for the tightening bolt.
Frame sizes 29 - 69:
tighten clamping screws
Frame sizes 79 - 189:
it is important that the face surfaces of the outer ring
one another. If they are not flush with one another when tensioning, the tolerance of the
insert shaft must be checked.
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
