SFU 3210‑4 Ball Screw Nut


The SFU 3210‑4 Ball Screw Nut is a precision linear-motion component designed for CNC machines, automation systems, and industrial equipment that require efficient, fast, and repeatable linear displacement. With a 32 mm screw shaft diameter and a 10 mm lead, it delivers comparatively rapid linear motion per revolution — making it ideal where speed and throughput matter, while still maintaining smooth, low‑friction operation. The nut uses a 4‑circuit internal ball‑recirculation design to reduce friction, minimize backlash, and enhance rigidity — which helps preserve positioning accuracy under load. Made of hardened alloy / bearing steel and manufactured with attention to durability, the SFU 3210‑4 nut offers long service life even under continuous or heavy-duty use. Its flanged nut design with standard mounting provisions makes it compatible with common support blocks and machine assemblies, giving engineers a reliable, easy-to-integrate choice for high-speed, medium-to-heavy duty linear-motion applications.
