Single preloaded nut type DIN 69051/5 for ground screws

The nut is a key engineering element for the mechanism of the screw: the nut accommodates the balls that create the precise, even and low-friction movement typical of B.B. brand screws.

Among the most popular components contained in our catalogue is the single preloaded nut for ground screws made according to DIN 69051/5 standards, which guarantees the customer not only interchangeability but also immediate availability. 

Just like the other standard B.B. nuts, the single preloaded nut type DIN 69051/5 for ground screws features the innovative internal recirculation system. It is a technology designed by B.B. specialists where 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. Increasing the number of circuits in the nut rolling track will result in larger load capacities, 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.
