State-of-the-Art Solutions

Diakont DA140 actuators incorporate state-of-the-art component designs to provide industry leading precision, power and reliability.

Advanced Roller Screw designs provide a high performance method for converting rotary torque into linear motion. With greater contact surface and a lack of backlash, Diakont’s advanced roller screws significantly exceed competitor solutions with higher reliability, lifetime, load capacity, tolerance to shock loads, absence of vibrations and efficiency output.

Permanent Magnet Synchronous Motor designs provide the ultimate solution for providing exact accuracy in high dynamic/force motion, while delivering exceptional reliability. The motor’s rotating motion is transferred to the output shaft by a “direct drive” system.
