Technical DetailsWeitai Hydraulic stands as one of China’s leading hydraulic suppliers and is among the earliest hydraulic enterprises to specialize in large-scale export operations. Over decades of dedicated expansion, we have evolved from a precise OEM manufacturing plant into a comprehensive industrial ecosystem integrating advanced research and development, global trading, and strategic investments.
As the designated Secretary Company of the Shandong Hydraulic Association (SDHA) and the official provincial comprehensive export platform, Weitai is proud to represent China’s elite engineering standards. Recognized as the 2018 Annual Outstanding Enterprise at the Shandong Equipment Manufacturing Association Annual Conference & Intelligent Manufacturing Forum, our structures, engineering practices, and products deliver superior volumetric efficiency, higher yield strength, and robust reliability compared to standard aftermarket components.
Our direct product integration on manufacturing lines of top-tier original equipment manufacturers like SANY, XCMG, and SDLG proves the heavy-duty capabilities of Weitai travel motors. Our factories operate under stringent ISO frameworks, and all materials undergo rigorous compliance checks to meet CE, RoHS, CSA, and UL standards.
Understanding the strict functional expectations, mechanical parameters, and dual-sourcing architectures required by procurement departments worldwide.
Global supply chain managers face major operational bottlenecks due to variations in component design. WTM series final drives are built to match standard dimensions, shaft splines, port configurations, and bolt circles. They can replace OEM drives from KYB, Nabtesco, Nachi, Rexroth, and Bonfiglioli without hydraulic system modifications.
Relying on a single hardware manufacturer presents significant logistical risks. By integrating Weitai Hydraulic as a designated supplier of track and swing motors, global heavy machinery distributors ensure continuous factory production and maintain steady, predictable pricing structures.
WTM motors use high-hardness planetary gears and wear-resistant friction linings, helping machinery operators reduce maintenance schedules, extend system longevity, and maximize return on investment (ROI) in demanding mining and infrastructure projects.
Modern construction equipment operates under extreme environmental conditions, from high-temperature desert construction to sub-zero high-altitude grading. To ensure reliable performance under these demands, Weitai Hydraulic developed the WTM series of final drives.
By integrating integrated relief valves, dual-speed swash-plate pistons, and spring-applied, hydraulically-released parking brakes into a single drive body, we provide excavator manufacturers with a ready-to-install propulsion module.
"In 2019 alone, the global demand and high performance characteristics of our travel drives led to the manufacturing and commissioning of over 40,000 Weitai travel motors worldwide. This volume was made possible through direct supply partnerships with major construction machinery groups, including SANY, XCMG, and SDLG."
This supply capability is supported by our specialized research divisions and state-of-the-art testing stations, where every travel motor goes through dynamic testing at full rated load. This testing helps guarantee low start-up torque, quiet gear operation, and steady volumetric output across high-pressure duty cycles.
Witness our engineering processes, quality control testing, and automated assembly lines in action.
Developing next-generation hydraulic drivetrains to meet global demands for energy efficiency, machine control, and high power density.
We are continuously researching and applying specialized anti-friction coatings like Diamond-Like Carbon (DLC) to piston shoes and swash plates. This helps reduce wear during cold starts and system pressure spikes, ensuring longer component life.
We are expanding the development of proportional electronic control valves integrated directly into WTM-07F and WTM-09 configurations. This supports automated drive adjustments and integration with smart machinery controller networks.
We are designing hybrid final drives that pair high-power-density hydraulic motors with high-torque electric generators. This provides a versatile drivetrain solution for low-emission municipal and underground mining machinery.
To meet the compliance requirements of different global markets, our material suppliers hold verified CE, RoHS, CSA, and UL certificates. Our manufacturing plants operate in strict compliance with ISO guidelines.
We regularly present our high-pressure travel motors and hydraulic solutions at leading global equipment and machinery exhibitions, including Bauma, Conexpo, and PTC.

Expert engineering insights on installation, troubleshooting, and sourcing configurations for hydraulic final drives.
Loss of track rotation power is commonly caused by: (1) internal hydraulic bypass due to wear on the piston block and swash plate; (2) a malfunctioning dual-displacement control valve that prevents stroke changing; (3) failure of the track pilot signal pressure; or (4) worn planetary gears inside the hub assembly. We recommend checking case drain line pressure before replacing components.
Yes. Our WTM final drives are designed to match standard mounting patterns. We manufacture drop-in replacements for brands like Nachi, Kayaba (KYB), Nabtesco, Eaton, and Rexroth. They align with existing frame bolt circles, sprocket links, and hydraulic port locations.
We achieve high efficiency by using precision-machined steel parts, keeping clearances tight between rotating elements, using high-quality internal seals, and dynamic balancing. This design helps minimize internal leakage and energy loss, even when operating at maximum system temperatures.
Our factories operate under ISO 9001 quality management guidelines. To support international compliance, our material suppliers hold CE, RoHS, CSA, and UL certificates. Additionally, every motor goes through dynamic testing at full rated load on our test benches before shipping.
