DFU Ball Screw

Product Introduction

Double nuts and single nuts are two types of ball nuts with the same installation dimensions, except for the length. However, the load capacity of double nuts is more than twice that of single nuts. For machinery that requires high rigidity and precise positioning under medium or heavy loads, the DFU Ball Screw, which is a double nut, is suitable.
To achieve this, a significant number of steel balls are positioned between the ball screw and the rolling raceway of the ball nut. These steel balls act as intermediate transmission bodies, facilitating the transformation of sliding contact into rolling contact through the relative movement between the screw and the nut. This not only enhances the load-bearing capabilities but also ensures smoother operation and improved precision in positioning.
In summary, the double nut configuration of the DFU Ball Screw makes it ideal for applications where high rigidity, precise positioning, and efficient load handling are required. By incorporating rolling contact through the use of steel balls, it offers superior performance compared to single nut alternatives.
