Ball Screw A-Series


Designed to meet the needs of recent developments in automation, as well as applications with strict tact time requirements, the A-Series of products offer greatly increased rotational speed and DN values. This high-speed capability keeps in step with improvements in ever-improving high performance motors.

Low Sound Pressure

Sound pressure has been reduced to 6dB when compared to conventional tube recirculation method ball screws. Additionally, the A-Series design greatly reduces high frequency sound, which provides excellent sonic performance.

Compact and Space Saving

To support the space efficiency of our customers’ equipment, the A-Series was developed as a streamlined nut body with a compact flange, reducing nut size by 30% and a nut weight by up to 50% when compared to conventional options.

DIN Standard Compatible

To support the versatility of our customers’ equipment, the A-Series (AH / AD) was developed to be compatible with the German Institute for Standardization.
