In the modern landscape of heavy machinery and precision engineering, the Slew Cylinder (also known as a helical hydraulic rotary actuator) has emerged as a critical component for achieving complex rotational movements within compact spatial envelopes. As a premier ODM Slew Cylinder factory, WEITAI Hydraulic integrates decades of metallurgical expertise with advanced fluid power dynamics to deliver solutions that redefine "High Torque Density."
Unlike traditional rack-and-pinion actuators, our slew cylinders utilize a sophisticated sliding helical gear design. This mechanism converts the linear motion of a piston into high-torque rotation through multiple helical splines. The result? A self-locking, zero-leakage system capable of holding massive loads at any intermediate angle without the need for external brakes.
WEITAI Hydraulic is one of the leading mobile hydraulic suppliers in China. Starting from OEM production for North American Tier-1 clients, we have evolved into a global powerhouse in manufacturing, trading, and hydraulic investment.
Our ISO-certified facilities ensure that every component meets rigorous international standards. With CE, RoHS, CSA, and UL certified material suppliers, we guarantee reliability in every rotation.
Serving over 50 countries, we understand localized engineering requirements—from the extreme cold of Nordic mining sites to the high UV exposure of Australian solar farms.
The global procurement shift towards Chinese hydraulic manufacturers like WEITAI is driven by more than just cost. It is about the Integration of Value Engineering.
China's industrial clusters allow for rapid prototyping. We can take a custom ODM drawing and produce a functional prototype in significantly shorter lead times compared to Western counterparts.
Our slew cylinders use high-strength alloy steels and specialized heat-treatment processes that ensure the helical splines withstand millions of cycles under maximum load.
By producing for diverse industries (construction, marine, energy), we cross-pollinate technical innovations, such as improved seal designs that prevent ingress in underwater applications.
Used in timber harvesters and fruit picking attachments where 360-degree rotation and precise positioning are vital for efficiency and tree health.
Critical for tilt-rotators on excavators, allowing operators to tilt buckets up to 90 degrees and rotate 360, turning a standard machine into a multi-tool powerhouse.
Slew drives are the heart of concentrated solar power (CSP) trackers, ensuring mirrors follow the sun with sub-degree accuracy throughout the day.
Our WL series provides corrosion-resistant rotation for crane booms and steering gear on commercial vessels operating in harsh saltwater environments.
Providing reliable rotation for fire truck ladders and aerial platforms where failure is not an option and safety factors are paramount.
WEITAI provides end-to-end logistics, including DDP/CIF shipping, customized export packaging, and all necessary documentation for seamless customs clearance.
WEITAI factories are ISO certified. Our material suppliers have obtained CE, RoHS, CSA, and UL certificates. We don't just manufacture; we engineer reliability. Every helical hydraulic rotary actuator undergoes a 100% factory test before shipment.

Our prices are subject to change depending on raw material costs (high-grade steel), order volume, and customization requirements (e.g., special coatings, integrated valves). We provide updated price lists upon company inquiry.
For custom samples, the lead time is approximately 7-14 days. For mass production, it ranges from 20-30 days after final design approval and deposit. We prioritize meeting tight project deadlines through optimized production scheduling.
The helical gear design naturally provides high internal friction and zero internal leakage. Our actuators are designed to hold their position indefinitely under static loads, acting as a mechanical lock unless hydraulic pressure is applied to move them.
Yes, we provide comprehensive documentation including Certificates of Analysis/Conformance, Origin Certificates, Insurance, and all relevant export documents required for your region.
We provide a 1-year comprehensive warranty on materials and workmanship. Our commitment is to resolve any technical issues to the customer's full satisfaction, ensuring long-term operational uptime.
