Center Flange Nut
Greater Rigidity and Precision
Central Force Transmission
The central flange position enables symmetrical and direct force transmission to the nut, significantly reducing torsional and bending loads. This results in higher overall rigidity of the ball screw drive and sustainably improves positioning accuracy.
