The mechanical grafts Van Der Graaf are available in execution for coupling between two shafts (FK ... a) and for flange coupling (type FK ... f).
The insertion takes place by means of a lever control, which provides the expansion of a friction material ring, on an outer bell.
The operation is dry and is distinguished by the simplicity of construction and for the absolute absence of residual friction in the disengaged position.
The main use is as a power take off (especially on board boats) for auxiliary controls. Detailed catalogs are available. Couples from 80Nm to 640Nm.
