Permitted Shaft Misalignments
ROBA
®
-ES coupling compensates for radial, axial and angular
shaft misalignments (Fig. 3) without losing its backlash-free
function. However, the permitted shaft misalignments indicated in
Table 3 must not simultaneously reach their maximum value.
If more than one kind of misalignment takes place simultaneously,
they influence each other. This means that the permitted
misalignment values are dependent on one another, see Fig. 4.
The sum total of the actual misalignments in percent of the
maximum value must not exceed 100 %.
The permitted misalignment values given in Table 3 refer to
coupling operation at nominal torque, an ambient temperature of
+30 °C.
If the coupling is operated in other or more extreme operating
conditions, please contact the manufacturers.

Shaft Alignment
Exact alignment of the shafts improves the running smoothness
of the coupling substantially, reduces the load on the shaft
bearings and increases the coupling service lifetime.
We recommend alignment of the coupling using a dial gauge or
special laser on drives operating at very high speeds.
