Low Sound Pressure

Sound pressure has been reduced up to 6dB when compared to conventional tube recirculation method ball screws.
Additionally, the AD Series design greatly reduces high frequency sound, which provides a pleasing improvement in
sonic performance.

High Speed

Designed to meet the needs of recent developments in automation as well as applications with strict takt time
requirements, AD Series Side Deflector Ball Screws offer greatly increased maximum rotational speeds and DN values.
This high speed capability keeps in step with improvements in high performance motors.
AD Series ball screws deliver a maximum DN value of 100,000 (twice that of conventional products) and a maximum
rotational speed of 5,000 min-1.


In an effort to support the space efficiency of our customers`equipment, Kuroda has developed a streamlined nut body with
a compact flange, reducing nut size by 30% and nut weight by up to 50% when compared to conventional options.
