DA actuators are suitable for demanding applications in automation and robotics, resistance welding, machine tool positioning, semiconductor manufacturing, packaging machines, and many other fields. They can be used as alternatives to hydraulic and pneumatic cylinders, doing away with the need for power packs and compressors.
The advanced roller screw design provides a high-performance method for converting rotary torque to linear motion. With a high level of surface contact and minimal backlash, the DA unit roller screws are ultra-reliable and have a long working life while offering excellent load capacity, tolerance to shock loads, absence of vibration, and output efficiency.
DA actuators incorporate integrated permanent magnet synchronous motors (PMSM) that are said to maintain accuracy in highly dynamic and/or high force applications. Furthermore, efficiency is achieved because the motor’s rotating output shaft is directly coupled to the actuator’s drive mechanism.
The actuators can produce a continuous force of up to 22,300N and speed of up to 833mm/s. Standard units have a nominal backlash of less than 0.1mm, zero backlash options are also available. DA actuators are claimed to operate across a temperature range from -40 to 100°C, shock and vibration and are available with IP66 ratings.
