Expanding shaft adapter

Adapter sleeves for working with different diameters. They allow for quick adjustment to different roll core diameters. They are mounted on another expanding shaft of smaller diameter or on a steel bar. The anchoring method can either be via the expansion of the inner shaft or a clamping system. An expanding shaft is used as the base shaft; its expansion secures the adapter. The adapter has a clamping system that closes, securing the base shaft on which it is mounted. This base shaft can be a fixed bar.
