Cylindrical single nut with thread for rolled screws and ground screws

The difference is in the detail: inside recirculating ball screws, it’s the nut that makes the difference. Thanks to the perfect integration of the balls and nut designed by B.B. S.r.l., the screws guarantee the precise, even and low-friction movement that will enhance the performance of machines used in any industrial sector. The secret is in the innovative internal recirculation system that B.B. also applies to the cylindrical nut with thread for rolled screws and and ground screws.

Just like for all the other nuts designed by B.B., 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 the number of circuits must be increased in the nut rolling track according to the information in the technical characteristics table.

For long-pitch nuts, B.B. has chosen a different system: all the balls run along the entire length of the rolling track, exiting one end and re-entering the other via special deflectors.
