5.3 Aligning the coupling
34 Edition 09/2022 M3560-02en
The recommended alignment values are specified as numerical values in Distances between
teeth VA and recommended alignment values for angular and radial misalignment
(Page67) . Do not align the coupling more accurately than this, as the lubrication film form-
ation will then be compromised.

5.3.2.1 Axial misalignment5.3 Aligning the coupling
Set the axial misalignment ΔKa to a value within the permissible tolerance range for the S
clearance.
The values for the S clearance are to be considered as the maximum permissible increase in
the hub distance of the coupling.
You can find the values for clearance S under Clearance S (Page66).
5.3.2.2 Angular misalignment5.3 Aligning the coupling
The ZNN, ZNNV, ZNZS and ZNZV types compensate for positional deviations of the shaft
ends to be connected up to a maximum angular misalignment of ΔKw=0.5°.
The ZNNA and ZNZA types compensate for positional deviations of the shaft ends to be con-
nected up to a maximum angular misalignment of ΔKw=0.2°.
Determine the value ΔS (ΔS = S
