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

These models use 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). They demonstrate improved axial rigidity compared to the SDA-V.
The SDAN-VX is the Full-Ball version of the SDAN-V.

Features

High Speed

The circulation components picks up balls in the tangential direction to achieve a maximum rotational speed of 5,000 min^-1 (DN value: 180,000). Torque remains stable even during long periods of high-speed operation.

Conforms to DIN Standards

The outer diameter is up to 30% more compact than previous THK products, enabling compact machine designs. Nut dimensions conform to ISO standards (ISO 3408).

Picks Up Balls in the Tangential Direction

Newly developed circulation components enable an ideal ball circulation structure.
