Product Description

At this diameter, the SFU1204 sits toward the smaller, more precise end of the ball screw range: a 24mm nut outer diameter, 10mm flange thickness, 40mm nut length, and 30mm flange width, with a single circuit of four recirculating balls (1×4). Rigidity is rated at 26 N/μm - a meaningful number mainly in how it resists deflection under axial load, which matters more than raw load capacity for equipment where positioning accuracy has to hold steady rather than drift under repeated cycles.

 

Material options include alloy steel, chrome-molybdenum alloy steel, stainless steel, and high-speed steel, chosen based on load, corrosion exposure, and operating temperature. Dynamic rated load runs 902N, static rated load 1844N, with rigidity at 26 N/μm - numbers that put this screw solidly in the small-diameter precision category rather than the heavy-load category, appropriate for equipment where positioning accuracy matters more than raw force.

 

It's used in industrial automation (robots, automated assembly lines, warehousing systems needing precise position and speed control), precision instruments (microscopes, measuring equipment, optical instruments), and medical equipment (X-ray systems, CT scanners, surgical robots) where motion accuracy directly affects image quality and patient safety.
