Checking the radial alignment
▪ Firmly clamp a dial gauge to one of the couplings or to the shaft. The piston of the dial
gauge must lie against the crown of the other half-coupling.
▪ Set the dial gauge to zero.
▪ Turn the coupling and write down the measuring result after every quarter turn.
▪ Alternatively, the radial coupling alignment can also be checked with a ruler.
NOTICE
The radial deviation of the two coupling halves must not exceed the maximum val-
ues found in table "Maximum permissible shaft displacement ΔS
This requirement applies to every operating status – including operating temper-
ature and inlet pressure.
Checking the axial alignment
NOTICE
The axial deviation of the two coupling halves must not exceed the maximum values
found in table "Permissible gaps S and S2". This requirement applies to every oper-
ating status – including operating temperature and inlet pressure.
