At three locations in Germany, HKS develops and produces high-quality rotary actuators such as the successful I-DA-H. Due to its especially high degree of functionality and precision, this versatile rotary actuator is used worldwide in all industrial areas.
The I-DA-H is the universal actuator made by HKS. It is an advanced development of the hydraulic DA-H rotary actuator. In contrast to cylinders, rotary actuators do not require external bearing support and can achieve significantly larger swing angles. There are two different principles underlying actuator function: the helical rotary actuator and the rack-and-pinion principle. The I-DA-H is a helical rotary actuator based on multiple helical gears. The linear movement of the piston is converted into a rotational movement via the multiple helical gears. The longer the linear movement of the piston, the greater the rotational movement. The outer dimensions of the innovative I-DA-H are flexible concerning design and it offers many technical features. The rotary actuator is suitable for use with working pressures up to 250 bar and for torques up to 250,000 Nm. In its standard version, the I-DA-H has an angle of rotation of up to 360° and a special angle of rotation of up to 1,500°. Any intermediate rotation angle is possible, so the rotary actuator can be integrated seamlessly into existing systems. No external end stops are required because the pistons can be run to their end stop positions and loaded. Thanks to optimized end position cushioning, which is standard, the mass moment of inertia is decelerated smoothly. This allows the I-DA-H to relieve the load on the machine and increase the service life of the entire system. All sliding surfaces and gearing are surface hardened, so the rotary actuator is subject to almost no wear and its effectiveness is maximized. The standard camshaft enables sensing of the angle of rotation and end position.
