ISO 3408 Compliant Compact Type SDA-V/SDA-VZ

This ball screw contains newly developed circulation components that give it an ideal ball circulation structure (maximum DN value: 180,000). The nut dimensions conform to DIN standards (DIN69051). Furthermore, the use of the newly developed thin film seal reduces the length of the nut, achieving more compact design for devices. This is the full-ball type version of the Model SDA-V (maximum DN value: 180,000).

Screw shaft diameters (mm) : 10,12,14,15,16,20,25,28,31,32,36,38,40,45,50

Features

High Speed

Circulation components pick 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.
