In the realm of mechanical engineering, a Rotary Actuator is a sophisticated device designed to output rotational movement and torque through hydraulic, pneumatic, or electric power. Unlike linear cylinders that move in a straight line, rotary actuators provide a compact, powerful solution for tilting, lifting, and rotating heavy loads. As a premier Rotary Actuator Manufacturer, WEITAI specializes in Helical Hydraulic Rotary Actuators, renowned for their exceptional torque-to-size ratio and zero-leakage holding capabilities.
Our helical designs allow for massive torque output (up to 24,000 Nm) within a small footprint, ideal for space-constrained machinery like excavators and mining drills.
Unlike vane-type actuators, our helical sliding spline technology ensures the actuator holds its position indefinitely without mechanical brakes.
Engineered to handle massive axial and radial loads simultaneously, replacing the need for external bearings and complex linkages.
WEITAI Hydraulic is one of the leading mobile hydraulic suppliers in China with decades of experience. We are committed to providing excellent hydraulic products and services to both businesses and final users worldwide.
Starting from the production of OEM Hydraulic cylinders for North American Customers, we have grown to be an integrated company of manufacturing, trading, and investing. The hydraulic rotary actuator is one of our main products. Our factory is ISO certified and our material suppliers have all obtained CE, RoHS, CSA and UL certificates. We can design and customize according to drawings to meet the diverse needs of customers.
Years Experience: We started our business as an OEM factory. We have professional knowledge on the design and manufacturing for the hydraulic solutions.
Countries Served: WEITAI devotes to provide reliable product all over the worlds. Now we serve customers over 40 countries and regions.
Quality Guarantee: All the helical rotary actuators are 100% tested before delivered to the customer. One year guarantee is provided.
Choosing a Rotary Actuator Factory in China like WEITAI offers more than just competitive pricing. It provides access to a world-class manufacturing ecosystem that ensures scalability and rapid innovation.
We utilize high-grade alloy steels and precision forging techniques, ensuring each WL30 or WL40 series actuator withstands extreme pressures up to 3000 PSI.
Located near major shipping hubs, we ensure fast international delivery. Our lead times for mass production are optimized at 20-30 days, significantly lower than European counterparts.
From flange mounting to foot mounting, and rotation angles from 180° to 360°, our engineering team can replicate "Helac type" actuators or create entirely new designs based on your CAD files.
For global enterprises, compliance is non-negotiable. WEITAI ensures that every rotary actuator meets the stringent legal and safety requirements of the destination country.
Used in excavator tilt buckets, quick hitch couplers, and demolition tools. Our actuators provide the ruggedness required for 24/7 site operations.
Critical for basket rotation and boom positioning, where smooth motion and high safety factors are paramount.
Driving solar trackers and heavy-duty drilling rigs, where high torque and resistance to dust and moisture are essential.
The industry is moving towards Smart Hydraulics. WEITAI is at the forefront of this evolution, integrating sensor technology for real-time position feedback and health monitoring. Key trends include:
Rotation: 180°, 360° & Custom
Max Torque: 24,000 Nm+
Mounting: Foot, Flange, Weld-on
Durability: 1 Million Cycles Tested
WEITAI factories are all ISO certified. We use high-precision CNC machining and rigorous testing to ensure every helical hydraulic rotary actuator meets our "zero-defect" policy.
High torque, high bearing capacity for industrial use.
Enclosed moving parts, suitable for harsh environments.
High power density fits in tight construction spaces.
Zero internal leakages, smooth operation, no external brake required.
Eliminates bearings, linkages & brackets, reduces bill of materials.
In Overload Conditions - Hydraulic fuse, prevents mechanical damage.
