THK SDA-V and SDA-VZ Series Compact Caged Ball Screw (DIN Standard)
The THK SDA-V Series uses newly developed circulation components for an ideal ball circulation structure, reaching a maximum DN value of 160,000. Its nut dimensions conform to DIN standards (DIN69051), and a newly developed thin film seal shortens the nut, giving the whole device a more compact footprint. It’s suitable for a wide range of uses, from small electronic component machinery to large general industrial equipment, with 59 product combinations covering shaft diameters from 12mm to 50mm and leads from 4mm to 50mm.
Model SDA-VZ is the full-ball version of the SDA-V, carrying a maximum DN value of 130,000. Both use THK’s Caged Technology for smooth, quiet motion and long-term maintenance-free operation, and both comply with JIS, ISO, and DIN standards.
