Fitting the shrink disk
•
Before beginning installation, the hollow shaft and the stub shaft must be carefully cleaned.
Observe manufacturer’s instructions for handling lubricants and solvents.
Do not allow cleaning agent or solvent to affect surfaces with paint coating.
The bore of the hollow shaft and the stub shaft must be absolutely clean and free of
grease and oil in the area of the shrinkdisk seat.
This is essential for safe and reliable torque transmission.
Do not use contaminated solvents or dirty cloths nor cleaning agents containing oil
(such as paraffin or turpentine) for removing grease.

The outer surface of the hollow shaft must be lightly greased in the area of the shrinkdisk seat.
For a detailed view, refer to the dimensioned drawing in the gearunit documentation.
•
Place the shrink disk on the hollow shaft and fasten, if required. For the exact installation height (W) of
the shrink disk, refer to the dimensioned drawing.
For transporting and lifting the shrink disk it may be required to use a suitable lifting
device!
Make sure that the shrink disk cannot slip off the hollow shaft.
Do not tighten the tensioning bolts (5) until the stub shaft has been installed too.
•
Tighten the tensioning bolts (5) gradually one after the other, working round several times by quarter
turns.
•
Tighten all tensioning bolts (5) until the end faces of the inner ring (3) and the outer ring (4) are flush and
the maximum tightening torque of the tensioning bolts has been achieved. The correct alignment is to
be checked using a ruler. The max. tolerance is ± 0.2 mm.
The correct clamping condition can thus be checked visually.
