Fujian Guanwei Auto Parts Co., Ltd., operating under the brand GW JDM, has built its product catalog around a single operating philosophy: "compliance as the foundation, green as the wings, innovation as the soul." Founded in 1985 and headquartered in Nan'an, Quanzhou, Fujian, the company is recognized as a National High-Tech Enterprise and today maintains a catalog of 31 distinct products and services spanning differential components, pin shaft products, stamping and forging parts for new energy light trucks, aftermarket components, and manufacturing process services. This review walks through the full catalog structure to help industrial buyers understand what Fujian Guanwei actually offers and where its documented strengths lie.
Differential Products: Built for Power Distribution Under Load
The differential product line centers on components that support planetary gear sets and manage speed differences between wheels. The Differential Cross Shaft is constructed from solid forged steel for impact resistance, with integrated oil passage lubrication supporting four planetary gears for stable torque distribution. This component has been supplied to Heli Co., Ltd. for forklift applications.
The Fangsheng Axle Planetary Half-Shaft Gear is produced in 20CrMnTi case-hardening steel and customized to fit the HDZ255 single-stage reduction drive axle, available in multiple size configurations (14T34Tφ48 / 14T21Tφ46 / 10T*φ19). The Mercedes-Benz Transfer Case Gear functions as the central differential within the 4MATIC all-wheel-drive system, distributing power at a fixed ratio typically split 45% front axle and 55% rear axle across models including the C-Class, E-Class, S-Class, and GLC (including GLK). Rounding out this line, the Jiangling Planetary Gear Shaft serves light commercial vehicle drive axles (0.5–8 tons), engineering vehicle drive axles (3–6 tons), and new energy electric drive axle applications for Jiangxi Jiangling Chassis Co., Ltd.
Pin Shaft Products: Precision Fit Across Heavy-Duty Platforms
This is the catalog's largest category, covering cross shafts, kingpins, and related pin components for commercial vehicle axle systems. The Hande Axle Cross Shaft family includes model HD90149326581/82 for 40-ton mining axles and model HD469-2510014 for 35-ton and 45-ton trucks, both built from 20CrMnTi case-hardening steel. The Hande Axle Output Shaft supports the HDE3.5T central motor reduction drive axle for light trucks, while the Hande Axle Electric Fork Shaft uses 40Cr alloy steel for 13-ton single-stage and 16-ton wheel-side reduction axles.
For agricultural and light-truck applications, the Hande Axle Slider Upper and Lower Shells and Shock Absorber Bracket are manufactured in Q355B structural steel with custom irregular geometries. The Hande Upper Kingpin is engineered for 13-ton motor bridge applications using 20CrMnTi steel.
Beyond the Hande Axle portfolio, the Dana Steering Knuckle Kingpin (model CK1036) is made from 42CrMo quenched and tempered high-frequency material, noted in the source documentation as offering higher strength than common market alternatives using 45# steel or 40Cr, and is supplied primarily for Sinotruk heavy-duty trucks. The SCANIA Steel Plate Pin (model 199100520065) combines 40Cr quenched and tempered high-frequency steel with a phosphating treatment and spiral design, supplied in large quantities to Sinotruk, Shaanxi Automobile, and Dongfeng. The Yuchai Cross Shaft serves 16-ton and 18-ton rear axle configurations under both new and legacy TGX model designations. The Heli Tilt Cylinder Support provides fixed and articulated installation for forklift mast systems, resisting bending moments and impact forces. The Foton Spring Pin (A629200000105) in 40Cr material supports Foton Motor's heavy-duty truck, light-duty truck, bus, and pickup platforms. Finally, the Caterpillar Universal Joint, built from specialized 1E0778B material, is designed for excavators, bulldozers, loaders, and mining trucks.
Stamping and Forging Products for New Energy Light Trucks
This category addresses electric motor bridge applications with eight distinct parts: the Support Plate, Support Bracket, Spring Plate, Shock Absorber Bracket Assembly (Right), Spring Pressure Plate, Fixed Support, general Support, and Engine Gear Case Cover. Several components—supplied under Hande Axle model numbers HD90009321405/04 and A629200000105—are built in 20CrMnTi or 40Cr steel for applications on 3.5-ton motor bridges and the HDZ255 single-stage reduction drive axle.
Aftermarket Services and Manufacturing Capabilities
Beyond OEM supply, the catalog includes the GW Aftermarket Brand Components line, which the company positions as meeting international market access requirements for compliant global operation, supported by CE certification. Export markets for aftermarket and OEM products together include Southeast Asia, South America, North America, and the Middle East.
The catalog also lists three manufacturing service offerings. Heat Treatment Services cover isothermal normalizing, spheroidizing, quenching and tempering, carburizing, nitriding, and carbonitriding, with the heat treatment workshop operating under the CQI-9 standard. Surface Treatment Services include oxidation blackening, galvanizing, Dacromet, hot-dip galvanizing, PTFE, combined coatings such as ZiNi + PTFE and Xylar 2 + PTFE, DLC, molybdenum disulfide spraying, and phosphating, managed under CQI-12 standards. Product Development Services follow the TS16949 quality system flow, covering project initiation, FMEA, process flow design, 3D data design, prototyping, tooling design, matching tests, and OTS delivery, with a development cycle controlled within 90–150 days.
What the Catalog Signals to Industrial Buyers
Taken together, the 31 items in the Fujian Guanwei catalog reflect a product strategy organized around four pillars: differentials, pin shafts, new energy light truck stamping/forging parts, and service-based offerings. Customer cases referenced in company materials span forklift manufacturer Heli, axle manufacturer Fangsheng Axle, premium automaker Mercedes-Benz, heavy-duty axle supplier Hande Axle, global component supplier Dana Incorporated, commercial vehicle brand SCANIA, engine manufacturer Yuchai, commercial vehicle OEM Foton Motor, and equipment manufacturer Caterpillar. Each case in the source material ties a specific product model and material specification to a named customer application, giving buyers a documented reference point for material selection—whether 20CrMnTi case-hardening steel for wear resistance, 40Cr alloy steel for general structural strength, 42CrMo for high-frequency quenched applications, or Q355B for irregular structural parts.
For procurement teams evaluating Fujian Guanwei's catalog, the breadth across differential, pin shaft, and stamping/forging categories—paired with documented heat treatment and surface treatment process capability—positions GW JDM as a supplier capable of addressing multiple axle and drivetrain component needs from a single source, backed by quality system certifications including IATF 16949:2016, ISO9001, ISO14001, and ISO45001.
