Unbalance discs of the type XS
The unbalance setting of the unbalance discs of the type XS is car-
ried out on the scale on the fixed unbalance.
The centrifugal force can be steplessly adjusted by turning the outer
unbalance discs and adjusting them at the partial strokes. After ad-
justing the unbalances, the nuts and screws must be tightened with
the specified torque.
The centrifugal force can be adjusted with the unbalance discs of the
type XS according to the following table:
