Self-expanding and self-centering fully mechanical adaptors suitable to be mounted on a smooth or expanding carrier shaft, allow to block larger diameter cores.

Based on the same principle of operation of the new CLEV12 mechanical shaft, core locking happens by radial expansion of a steel balls set moved thanks to an outer sleeve with a drag function, these balls generate a pressure and then a torque on the inner core surface engaged on the shaft.

Transmitted torque is unlimited, its value depends only by the quality of the core.
