Recirculating system

Internal recirculation

With the internal recirculation system the whole rolling track of the nut is divided into several circuits in which the balls run in a closed cycle; at the end of each revolution the balls are brought back to their original position by a deviating return piece.

In order to obtain larger load capacities it is necessary to increase the number of circuits according to the information in the technical characteristics table.

For long-pitch nuts there is a system where all the balls run along the entire length of the rolling track, exiting one end and re-entering the other via special deflectors.
