Securing
For versions with shoulders:
1. Place the fastening element (1) with the long centring diameter into the shaft and secure it with the
locking screw (5).
For versions without shoulders:
1. Place the fastening element (1) with the long centring diameter into the shaft and secure it with the
locking screw (5). The fastening element (1) must be fully adjacent to the front side of the hollow
shaft.
Dismantling
1. Place the dismantling element (8) on the face end of the shaft.
2. Insert the correct circlip (2) into the outer locking groove of the hollow shaft and position the

3.6.2 Fitting a hollow shaft with shrink disc (Option: S)
NOTICE
Risk of damage to the gear unit if the shrink disk is installed incorrectly
• Do not tighten the tensioning bolts if the solid shaft is not installed. This would permanently deform
the hollow shaft.
Hollow shafts with shrink discs must be protected from dust, dirt and moisture. NORD recommends
option H/H66 (see chapter 3.14 "Installing the cover cap, air baffle (Option: H, H66, FAN, MF..,
MS…)").
The shrink disc is supplied ready for fitting. It must not be dismantled prior to fitting.
The solid shaft material must have a minimum yield strength of 360N/mm
2
. This ensures that no
permanent deformation occurs due to the clamping force.
Always observe the documentation from the manufacturer of the shrink disc.
