SFU 4010-4 Ball Screw Nut
The SFU 4010-4 Ball Screw Nut is a heavy-duty, high-capacity linear-motion component suited for industrial and CNC applications where high load-bearing capability, long travel, and fast linear displacement are required. Designed for a 40 mm diameter screw shaft with a 10 mm lead, each revolution moves the nut 10 mm along the shaft — enabling rapid long-axis movement for heavy loads. The nut’s design includes an internal ball recirculation system (4‑circuit) that ensures smooth, low-friction motion with reduced backlash and enhanced rigidity, even under high loads or during frequent motion cycles. Made from hardened alloy steel, both screw and nut are built for durability and longevity. Its robust dimensions and mounting compatibility make SFU 4010-4 ideal for heavy CNC machines, large‑scale automation equipment, industrial positioning tables, and any application demanding high stiffness, reliability, and efficient linear motion under load.
