Rolled Ball Screw SFU2505-4 for Precision Automatic Control Machines
Get repeatable, sub-micron positioning accuracy in high-cycle automated systems — without the downtime or recalibration headaches common with worn or low-grade leadscrews. The rolled ball screw SFU2505-4 delivers OEM-grade precision for automatic control machines where motion integrity directly impacts yield and machine uptime. Preloaded double-nut design (SFU2505-4/2 variant available) eliminates axial backlash — critical for closed-loop servo systems Made from hardened alloy steel with ground raceways, not just rolled threads, ensuring 30%+ longer service life under continuous 10,000+ km stroke cycles OEM/ODM supported with custom shaft ends, lubrication ports, and preload tuning — no minimum order for engineering collaboration Backed by our in-house SKF-certified motion engineers who’ve solved >200 bearing & actuator integration cases in wind, steel, and automotive lines
