ISO 3408 Compliant High Speed SDAN-V/SDAN-VX type

The preloading system uses a double-nut preload system in which two ball screw nuts are combined using a spacer to eliminate backlash. The nut dimensions conform to ISO standards (ISO 3408). It demonstrates improved axial rigidity compared to the SDA-V.
The SDAN-VX is the Full-Ball version of the SDAN-V.
