Welcome to Shengan Machinery: 40 Years of Excellence in Excavator Undercarriage Manufacturing
July 30, 2026
For heavy machinery, the undercarriage represents one of the most critical structural components—bearing immense weight, enduring high-friction environments, and dictating overall operational efficiency. Since 1985, Fujian Shengan Machinery Development Co., Ltd. has stood at the forefront of crawler machinery component manufacturing, establishing a 40-year legacy of engineering excellence in Quanzhou, Fujian, China.
As excavator parts manufacturers specializing in casting, forging, precision processing, and global sales, Shengan Machinery delivers high-durability undercarriage components and Ground Engaging Tools (GET) designed to keep heavy equipment moving in the world’s harshest environments.
Heavy-Duty Industrial Infrastructure & Scale
Shengan Machinery combines decades of traditional craftsmanship with automated manufacturing power. Spanning an expansive 80,000-square-meter modern standard workshop, our facility is engineered for large-scale, high-precision production.
- Expert Workforce: Powered by over 500 skilled employees, including a dedicated team of 80 senior and middle-level technical engineers overseeing R&D, metallurgical testing, and quality assurance.
- Advanced Forging Capabilities: Operating heavy-duty forging lines ranging from 630 tons to 4,000 tons, enabling superior grain refinement and structural density in every forged component.
- Precision Machining & Heat Treatment: Equipped with advanced CNC lathe centers, specialized heat treatment furnaces (induction hardening, quenching, and tempering), and automated machining centers to guarantee tight tolerance control.
- Rigorous Metallurgical QA: Complete in-house testing equipment, including Chemical Testing Machines, hardness testers, and non-destructive testing devices to ensure zero-defect material integrity.
Our Core Product Portfolio
We engineer a complete suite of undercarriage spare parts and Ground Engaging Tools (GET) built for maximum wear life, high fatigue resistance, and seamless compatibility with crawler excavators and bulldozers:
| Product Category | Engineering Highlights | Application Focus |
| Track Rollers / Bottom Rollers | Deep induction-hardened tread rings, reinforced bronze bushings, and duo-cone seals for leak-proof lifetime lubrication. | Heavy loads, rocky terrain, impact resistance. |
| Carrier Rollers / Top Rollers | Precision-machined shafts and heat-treated shell bodies to maintain proper track tension and link alignment. | High-speed travel, wear resistance. |
| Front Idlers | Heavy-cast or forged shells paired with reinforced internal tension groups for optimal shock absorption. | Front impact absorption, smooth track guiding. |
| Drive Sprockets & Segments | Precision-cast tooth profiles hardened to resist abrasive wear and prevent chain pitch jumping. | Power transmission, anti-pitch stretching. |
| Track Links & Assemblies | Forged alloy steel link pitch chains, induction-hardened pins, and bushings for extreme torsional resistance. | Continuous traction, pitch stability. |
| Excavator Buckets & GET | Reinforced heavy-duty rock buckets, ditch cleaning buckets, and excavator attachment assemblies. | Mining, quarrying, heavy excavation. |
