NOTICE
Damage to property
Damage to the shaft end, the coupling parts and/or the parallel key.
• Note the handling instructions regarding assembly of the coupling parts.
Assembly of the coupling comprises the following steps:
• Assembling coupling parts with shaft-hub connection using a parallel key (Page31)
• Assembling coupling parts with shaft-hub connection using a pressurised oil interference
fit (Page32)
• Assembling the coupling (Page33)
5.2.1 Assembling coupling parts with shaft-hub connection using a parallel key5.2 Mounting the coupling
Procedure
1. Unscrew the set screw until a collision with the parallel key or the shaft is no longer pos-
sible.
2. Clean the bores and shaft ends.
3. Lubricate the cleaned flanged sleeve keyway and then insert the O-rings (12).
4. Lubricate the gear of the flanged sleeves (5).
5. Place the flanged sleeve (5) onto the shaft before mounting the coupling parts 1 (1) and
2 (2).
6. Coat the bores of coupling parts 1 (1) and 2 (2) and the shafts with MoS

assembly
paste (e.g. MicrogleitLP405).
7. Smear the parallel keyway in the area of the set screw using sealing compound (50).
8. Mount coupling parts 1 (1) and 2 (2) on the shaft.
WARNING
Danger due to bursting of the coupling
If you do not observe the information stipulated here when assembling coupling parts with
a tapered bore, then this can cause the coupling to burst in operation. There is a risk of
fatal injury from flying fragments. If a coupling bursts in an area at risk of explosion, then
this can result in an explosion.
• Mount coupling parts 1(1) and 2(2) with conical bore and parallel keyway on the shaft
in cold condition. Apply sealing compound (50) to the front of the hub on the shaft
face. Secure the coupling parts 1 (1) and 2 (2) with suitable end plates without pulling
the coupling parts 1 (1) and 2 (2) further onto the taper (fitting dimension = 0) or ac-
cording to the dimension drawing provided.
Information
Coupling parts with cylindrical bore
To make assembly easier, you can heat coupling parts 1 (1) and 2 (2) with cylindrical bore
up to a maximum of 80°C if required.
