 Note!
In the case of the shaft−mounted helical gearbox, the hollow shafts are
released to rotate freely in the central part, i.e. the hole diameter is
greater by 0.1 mm in this area! Provide for a sufficient length of the
machine shaft so that the machine shaft is guided on both sides.

4.3.9 Mounting the shrink disc with a rotating cover
 Stop!
¯ Do not disassemble new shrink disc.
¯ Never tighten clamping screws before the machine shaft has been
inserted, since otherwise the hollow shaft may undergo plastic
deformation.
¯ During operation, the shrink disc has to be covered so that it is safe
against contact by implementing suitable measures (e.g. cover).
¯ Degrease hollow shaft bore and machine shaft!
