SFU Ball Screw

SFU Series Ball Screw

The SFU Series Ball Screw is a single-flanged-nut ball screw assembly designed for controlled linear motion in CNC machinery, machine tools, industrial automation and positioning systems.

The SFU design combines a threaded screw shaft with a flanged ball nut and internal ball recirculation mechanism. As the screw rotates, the circulating balls transmit the rotary motion to the nut, producing controlled linear movement with low friction.

The SFU series is available with 12–100 mm shaft diameters, C3/C5/C7 accuracy grades, customized lengths and right- or left-hand thread options.

Both precision-rolled and precision-ground configurations are available for different performance and application requirements.
