In the high-stakes world of heavy machinery, the Nachi Final Drive system represents the pinnacle of torque delivery and reliability. As a leading OEM Nachi Final Drive manufacturer, Weitai Hydraulic has spent decades refining the intersection of Japanese engineering precision and Chinese manufacturing agility. Our role as a primary supplier to global excavator giants like SANY, XCMG, and SDLG underscores our commitment to world-class quality.
Weitai Hydraulic is one of China’s leading hydraulic suppliers, the earliest hydraulic enterprises specializing in export business for decades. We are committed to providing excellent hydraulic products and services to both businesses and final users worldwide. At the beginning, we were an OEM factory and have gradually developed into a comprehensive company integrating production, trade, and investment. Hydraulic motors are one of our main products. In addition to our own hydraulic factories, we are a shareholder of a high-quality hydraulic motor manufacturer. Our 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.
As the construction industry moves toward zero-emission sites, we are pioneering the development of electric wheel drives (WED-003) and electro-hydraulic final drives. Our roadmap includes integrating high-density permanent magnet motors directly into planetary gearboxes.
Future Nachi-compatible units will feature embedded sensors for temperature, pressure, and vibration monitoring. This "Digital Twin" approach allows for predictive maintenance, reducing downtime by up to 35% for large-scale mining operations.
Using proprietary heat-treatment processes, our latest gear sets offer 20% higher torque density. This allows for more compact final drives that can handle the extreme loads of the next generation of 50-ton excavators without increasing the footprint.
Our solutions aren't just components; they are engines of economic growth across various sectors:
Our "Factory 4.0" initiative focuses on Supply Chain Resilience. By vertical integration—owning shares in component manufacturers and maintaining a robust network of ISO-certified material suppliers—we mitigate the risks of global logistics volatility. This efficiency allows us to provide "Information Gain" to our clients: we don't just ship parts; we provide lead-time certainty and cost-stability in an unstable market.
The Motor products include but are not limited to travel motors, swing motors and wheel-motors. Our motors have an advanced design structure and provide high volume efficiency, high strength and good stability which far superior than our competitors’ motors. This resulted in the demand and production of over 40,000 Weitai travel motors in 2019. Weitai travel motors are now even included in the production line for excavator manufacturers such as SANY, XCMG and SDLG.
Compliance isn't optional. Our products meet CE, RoHS, CSA, and UL standards, ensuring seamless entry into European and North American markets. We handle all regulatory documentation to streamline your import process.
As the Shandong Hydraulic Association’s (SDHA) Secretary Company, Weitai acts as a comprehensive export platform. We offer localized technical support and have established a warehouse system to ensure spare parts are available when and where you need them.
Our technical team can design and customize according to drawings to meet the diverse needs of customers. Whether it is a modification of a Nachi PHV series or a completely new travel drive design, we provide the expertise to execute it.
Global enterprises aren't just looking for manufacturers; they are looking for Strategic Partners. Procurement directors now prioritize:

Yes, our OEM travel motors are designed to be direct "bolt-on" replacements for the Nachi PHV series. We ensure that the mounting dimensions, hydraulic port sizes, and torque outputs match or exceed the original specifications.
For standard models, we maintain a robust stock for immediate shipping. For custom engineering or large-scale OEM orders, lead times typically range from 4 to 8 weeks, depending on material specifications and testing requirements.
Each unit undergoes a rigorous multi-stage testing process, including high-pressure leakage tests, torque efficiency validation, and noise level monitoring. All data is recorded and traceable back to the production batch.
Absolutely. We are currently a market leader in China for electric wheel drives (WED series) and provide full technical consulting for excavator manufacturers transitioning from diesel-hydraulic to electric-hydraulic platforms.
Our global operations are managed from No. 36 Miao Ling Road, Laoshan District, Qingdao, China 266061. We are open Monday-Friday: 9:00 am to 6:00 pm.
Our material suppliers must hold CE, RoHS, CSA, and UL certificates. Our internal processes are ISO certified, ensuring we meet international manufacturing excellence standards.
