The SFAx-040 Ball Screw Series is engineered for applications that demand high precision, efficiency, and long service life. Manufactured with tight tolerances and an optimized recirculation design, these ball screws deliver smooth motion, low friction, and excellent positioning accuracy, making them well-suited for automation, CNC machinery, and high-duty industrial systems. The SFA series also offers strong load capacity and rigidity while maintaining consistent performance over extended operating cycles. SFA ball screw nuts feature a compact design, low noise operation, and enhanced sealing with extra dust protection to help prevent contaminants from entering the assembly—extending operational lifespan and ensuring reliable performance in harsh, fast-paced environments. With a maximum static load capacity of up to 13,943 kgf and dynamic load capacity up to 5,035 kgf, along with an available diameter of 38 or 40 mm and travel lengths from 5 to 40 mm/rev, the SFA series provides a practical balance of performance, durability, and flexibility for engineers seeking reliable motion solutions without added integration complexity.
