SFU 2010-4 Ball Screw Nut
The SFU 2010-4 Ball Screw Nut is a precision linear-motion component built for CNC machines, automation systems, and other machinery where accurate, repeatable linear displacement is needed. It works with a 20 mm diameter screw and a 10 mm lead, translating each full screw revolution into 10 mm of linear travel — giving faster traverse compared to lower-lead screws. The nut uses an internal recirculating ball circuit (4‑circuit design) that reduces friction and backlash, improving rigidity and positioning accuracy under load. Constructed from hardened bearing/alloy steel for both nut and screw, it delivers good durability and lifespan even under repeated or heavy-duty use. Its flanged nut design uses a standard mounting arrangement, compatible with common supports and nut‑housings, making SFU 2010-4 a convenient and dependable choice for linear-motion axes in CNC, milling, or automation setups.
