The DFDA end plug type ball screw belongs to the end guide circulation structure, and the ball closed-loop circulation is completed through dedicated end plug reversers at both ends of the screw nut. The reflux channel adopts a tangential optimization design, with smooth ball reversing transition and no hard impact, improving the high-speed operation stability of the screw from the structural root. This series includes two major models, SFDA and DFDA, tailored specifically for the working conditions of precision high-speed equipment.
