Features

High Torque and Versatile Applications
This rotary actuator offers a variety of torque types, including 1.0, 2.0, 2.5, 3.0, 5.0, and 7.0 N·m (0.74, 1.48, 1.84, 2.21, 3.59, and 5.16 ft·lbf). As a result, it adapts easily to different industrial needs. Moreover, it operates efficiently at an air pressure of 0.5 MPa (73 psi), ensuring reliable performance in a broad range of applications.

Precision and Rigidity
The actuator uses cross roller bearings to achieve exceptional precision and rigidity. Consequently, it delivers smooth operation at speeds ranging from 0.2 to 7.0 s/90°, providing consistent and high-performance results in demanding environments.

Effortless Installation and Versatility
Thanks to its design, the workpiece can be directly mounted to the bearing, simplifying the setup process. Additionally, the actuator comes with optional mounting parts, offering flexibility to accommodate various mounting formats and setup configurations.

Compact Design for Space-Saving
Due to its thin construction, this actuator can easily fit into narrow spaces, making it perfect for compact setups. Furthermore, the large diameter hollow shaft allows for easy piping and wiring, reducing clutter and improving installation efficiency.

Enhanced Durability with Advanced Features
The actuator is equipped with a newly developed pressure-resistant shock absorber. As a result, it provides smooth control at the end of the stroke, minimizing vibrations and ensuring a longer lifespan, even in dynamic environments.
