In the contemporary industrial sector, the demand for precision, compactness, and extreme torque has positioned helical hydraulic rotary actuators as the gold standard for motion control. Unlike traditional rack-and-pinion systems, the helical gear design—pioneered by industry leaders like HKS and perfected through WEITAI’s ODM innovations—offers unparalleled power density. Today, these components are critical in the evolution of "Smart Heavy Machinery," where space is at a premium and reliability is non-negotiable.
From the mining fields of Australia to the infrastructure projects in Southeast Asia and the agricultural heartlands of North America, the transition toward high-efficiency hydraulic systems is accelerating. As a premier ODM/OEM partner, WEITAI Hydraulic bridges the gap between complex engineering requirements and cost-effective manufacturing, delivering solutions that meet the rigorous E-E-A-T standards required by global procurement directors.
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 of OEM/ODM Expertise in Motion Solutions
Standard & Custom Actuator Models in Catalog
Countries Served with Localized Support
Factory Testing Before Global Export
Development of actuators with integrated position sensors and IoT connectivity for predictive maintenance and real-time telemetry.
Optimizing seal technology and internal friction to allow for biodegradable hydraulic fluids and lower energy consumption.
Advancing metallurgical coatings for actuators used in subsea, arctic, and high-salinity maritime environments.
The industry is moving toward "Intelligent Motion." Our roadmap includes the miniaturization of high-torque units to support the electrification of mini-excavators and service robots. By reducing the bill of materials through "Eliminating Bearings & Linkages," we simplify machine architecture while increasing structural integrity.
Utilized in tilt-rotators for excavators and demolition shears, providing 360-degree versatility in urban environments.
Heavy-duty WL series actuators manage the positioning of drill booms and roof bolters in high-vibration underground mines.
Ensuring smooth basket rotation and boom extension with zero internal leakage, critical for operator safety.
High torque, high bearing capacity in a footprint significantly smaller than traditional cylinders.
Enclosed moving parts make our units suitable for the harshest environments (dust, mud, salt).
High power density allows the actuator to fit in tight spaces where linear cylinders cannot operate.
Zero internal leakages and smooth operation mean no external brake is required to maintain position.
Eliminates the need for external bearings, linkages, and brackets, reducing your overall bill of materials (BOM).
Functions as a hydraulic fuse in overload conditions, preventing catastrophic mechanical damage to the machine frame.
WEITAI factories are all 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.
Our team concentrates on mobile hydraulic components. Together with our professional technicians and staff, we are dedicated and passionate about our mission. All the helical rotary actuators are 100% tested before delivered to the customer. A one-year guarantee is provided as a testament to our reliability.
Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contacts us for further information.
Yes, we require all international orders to have an ongoing minimum order quantity. For specific batch requirements or prototyping, please consult our engineering team.
Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.
For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment and final approval.
We warranty our materials and workmanship for one year. It is our company culture to resolve all customer issues to total satisfaction, regardless of warranty status.
We use high-quality export packaging and specialized hazard packing if required. Sea freight is the most cost-effective solution for large volumes, while Express is available for urgent samples.
Whether you need a drop-in replacement for an HKS unit or a completely new motion control solution for a specialized vehicle, WEITAI's engineering team is ready to assist.
Please let us know your demand and we will be in touch within 24 hours.
