This core pre-centering system ensures a concentric core centering.
The core pre-centering system which mentioned shafts are equipped with, is a combined system of expandable keyrows.
When the shaft is inflated, a first set of 3 keyrows with special centering keys expand to pre-center the core, preparing it to be secured by a second set of long polyurethane keys, which firmly lock the previously centered core.
