Precision Caged Ball Screw Compact Type SDA-V/SDA-VZ

A ball screw with newly developed circulation components that give it an ideal ball circulation structure. (Maximum DN value: 160,000)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 a more compact design for the device. This is the full-ball type version of the Model SDA-V. (Maximum DN value: 130,000)

Screwshaftdiameter(mm) : 10,12,14,15,16,20,25,28,31,32,36,38,45,50

Features

High Speed

Picks up balls in the tangential direction and achieves a maximum rotational speed of 5,000 min^-1 (DN value: 160,000).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.Enables 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.
