At its core, a hydraulic rotary actuator utilizes a helical gear design to convert the linear motion of a piston into powerful rotational torque. When hydraulic fluid enters the cylinder, the piston slides axially. Due to the helical splines on the shaft and the inside of the piston, this axial movement forces the shaft to rotate.
Unlike standard cylinders, helical actuators offer immense torque in a compact envelope. The multiple helical gear teeth share the load, ensuring smooth operation and high resistance to shock loads, which is vital for heavy-duty machinery.
The precision-engineered internal splines provide a "self-locking" tendency under static conditions. This means it can hold any intermediate angle of rotation without external brakes, offering unparalleled safety in aerial platforms and construction arms.
Our ISO-certified factory integrates advanced CNC machining with rigorous quality control. We leverage China's comprehensive industrial supply chain to provide OEM and ODM services that rival European and American standards at a more competitive price point.
With decades of experience serving North American and European markets, we don't just export; we engineer. From WL10 to WL40 series, we customize torque outputs (up to 18000 Nm) and rotation angles (180° to 360°) based on specific technical drawings.
Our material suppliers hold CE, RoHS, CSA, and UL certificates. This ensures that every component exported meets the strict regulatory requirements of the destination country, facilitating seamless integration into your final products.
The global hydraulic market is shifting towards digitalization and sustainability. WEITAI is at the forefront of this transition, focusing on energy-efficient actuators and high-durability materials for harsh environments.
