Engineered for extreme environments, delivering superior positioning accuracy and compact structural high torque density.
In modern structural engineering and heavy industrial automation, the demand for precise rotational control in confined spaces is expanding rapidly. The L30-65 type rotary actuators represent the pinnacle of helical sliding spline technology, combining compact footprints with extreme torque output. As a leading manufacturer and exporter with a dedicated OEM/ODM facility, WEITAI Hydraulic focuses on delivering heavy-duty rotary actuators engineered to meet and exceed global reliability criteria.
Helical sliding spline technology operates on a simple yet highly effective principle: hydraulic pressure acts on a piston with internal and external helical teeth, converting linear motion into powerful angular rotation. Designed as a direct, high-performance alternative to traditional pinion-and-rack configurations or complex hydraulic linkages, the L30-65 series is optimized for load-bearing structures, agricultural equipment, and demanding construction attachments. By integrating the bearing, shaft, and actuation mechanism into a single enclosed casing, we deliver robust solutions that withstand severe environment loads.
Where heavy hydraulics meet next-generation precision and materials engineering.
Our upcoming product generation introduces integrated digital angle sensors and CAN-bus control compatibility. This allows construction vehicles to obtain real-time angular feedback for autonomous operations and telemetry monitoring.
We are integrating state-of-the-art carbon-nitride surface coatings on our helical gear teeth. This reduces sliding friction under massive shock loads, drastically extending the service life of our actuators in critical projects.
Our proprietary polyurethane and PTFE composite seals provide continuous protection against leakages. They maintain pressure boundary integrity from -40°C up to 110°C, ensuring compliance with global environmental regulations.
Rotary actuators are the muscles behind high-performance machinery. The L30-65 Series provides crucial advantages across many distinct macro sectors:
Operating from China's premier industrial hydraulic cluster, WEITAI Hydraulic integrates a state-of-the-art manufacturing infrastructure. Our manufacturing facilities are fully ISO-certified, applying strict quality controls throughout each phase. Every component of our helical sliding spline assembly is produced utilizing high-precision CNC gear grinding and heat-treatment centers to prevent structural fatigue.
By cooperating with CE, RoHS, CSA, and UL certified material suppliers, we ensure traceablity of all raw inputs, including premium carbon steel, high-pressure seals, and mechanical fasteners. This robust supplier ecosystem guarantees that our clients receive components that comply with strict international regulatory standards. Our advanced material sourcing strategies, paired with lean manufacturing systems, enable us to maintain a consistent 20-30 day mass production lead time, protecting your global procurement operations from supply chain delays.
Why OEMs and industrial distributors in more than 50 countries trust WEITAI.
Generates high output torque with substantial cantilever load resistance in a compact envelope.
Fully sealed housing prevents ingress of water and dirt, making it ideal for harsh operating conditions.
High power density allows installation in narrow structural spaces without compromising overall torque output.
Zero internal bypass leakage and smooth movement eliminates the need for complex external braking setups.
Reduces structural components by eliminating external bearings, linkages, and structural brackets.
Acts as an integrated mechanical shock-absorber, protecting internal components during extreme load spikes.
International trade demands meticulous execution. WEITAI provides comprehensive logistical support to guarantee efficient delivery. We supply complete technical documentation, including Certificates of Analysis (CoA), Certificates of Conformance (CoC), mill test certifications, and verified Certificates of Origin to expedite customs clearance globally.
To ensure transit protection, we package our products in heavy-duty, moisture-proof, export-approved wooden crates. If your operation requires specialized hazardous packaging or temperature-controlled containers, our logistics experts customize packaging protocols to secure your assets. Our technical engineering division maintains 24/7 communications, supporting our global client base through structural design validation and technical alignment checks.
Technical and commercial information for purchasing agents and engineers.
Our pricing structures depend on material cost indexes, customization requirements, and order volumes. Please reach out to our team with your application drawings, and we will send a detailed technical and commercial proposal within 24 hours.
Yes, we establish regular MOQs for international orders. For engineering prototype trials or distributor samples, please contact our sales office to request custom purchase arrangements.
Absolutely. We provide complete manufacturing documentation, including Certificates of Analysis/Conformance, material test reports, import/export origin certificates, and shipping insurance policies where required.
Prototype samples are completed within approximately 7 working days. For series production, manufacturing takes 20-30 days upon receipt of technical approval and deposit. We work to adjust scheduling to match critical OEM project timelines.
We accept wire transfers (T/T), L/C, Western Union, and PayPal. Our standard terms are a 30% deposit in advance of manufacturing, with the remaining 70% balance paid upon presentation of the Bill of Lading (B/L).
We provide a 1-year warranty covering material quality and workmanship. Our technical customer service division is committed to providing prompt support and resolution for any issues.
We utilize export-grade packaging with robust internal support structures and rust inhibitors. For complex machinery layouts or custom shapes, we create custom transit bracing to prevent shifting during maritime transit.
Shipping fees are calculated based on weight, volume, and destination. Air cargo is fast but costly, while ocean freight provides the most economical method for volume shipments. We supply accurate shipping weight calculations during our initial proposal phase.
