DA67 Roller Screw Actuators


The DA67 Series electromechanical actuators (EMAs) are equipped with an integrated motor and roller screw to provide superior performance in a compact space envelope.They are fitted with patented lubrication ports that support the actuator’s only re-lubrication maintenance requirements without having to disassemble the unit or remove it from the customer’s machinery.

Diakont is a full-cycle engineering, manufacturing, and service company that supplies motion control solutions that enhance the outstanding lifetime, safety, economy and efficiency of many industries. The DA67 Series actuators leverage Diakont’s proven actuator designs to provide industry leading reliability, force and precision.

Key Features

• Continuous force: up to 2670N (272kgf)
• Nominal backlash: 0.1mm
• Lead accuracy: 0.025 mm/300mm
• Speed: up to 833 mm/s
• Integrated motor and roller screw
• Lubrication ports for easy maintenance without disassembly

State-of-the-Art Solutions

Diakont DA67 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 more cumulative 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.
