Wholesale D6H Bulldozer Track Group

GFM specializes in the research and production of the D6H Bulldozer Track Group, providing high-performance and durable undercarriage solutions for construction machinery worldwide. As a heavy-duty machine, the D6H bulldozer relies on the track group as its core component, affecting traction, stability, and efficiency. Every track group undergoes strict material selection and process control to meet high-load demands.

• Material Selection: Chains, carrier rollers, idlers, and sprockets are made from high-strength alloy steel with carburizing and quenching treatment, ensuring excellent wear resistance and impact strength. Chain hardness is controlled for durability and vibration absorption.
• Precision Manufacturing: CNC machining and precision milling ensure accurate engagement of chains and gears. Components are dimension-checked before assembly for stable, synchronized track group performance, reducing maintenance frequency.
• Functional Optimization: Optimized contact surfaces and efficient lubrication reduce vibration and noise while maintaining smooth operation during long hours.
• Strict Quality Control: Each bulldozer part is tested for tensile strength, wear, and temperature cycles to guarantee performance under extreme conditions, with all quality data recorded for reliability.

At GFM Factory, we use oil instead of grease for bulldozer track links due to its superior lubrication and performance. Unlike grease-lubricated track links, oil-lubricated systems have more space between the pin and the bushing. After the pin is pressed into place, the space is vacuum-sealed and filled with oil, ensuring the gap is fully occupied for optimal lubrication. This process also checks that the track’s seal is intact, which is critical for preventing wear and ensuring the track performs at its best.

Oil is the ideal choice for track links, providing enhanced wear protection, effective heat dissipation, and helping to keep contaminants out. It also reduces the need for frequent maintenance. These benefits make oil-filled bulldozer track links a durable, efficient, and reliable solution for heavy-duty machinery, ensuring long-lasting performance.

Factory Advantages

Since 2011, GFM has specialized in manufacturing undercarriage components for bulldozers and excavators, becoming a trusted supplier of bulldozer part and track group products. With advanced equipment, strict processes, and a professional team, we provide high-durability, reliable undercarriage solutions for global construction machinery users.

• Mature Experience and Structural Knowledge: With 14 years of manufacturing experience, GFM has deep understanding of stress patterns and wear characteristics of undercarriage components, as well as real-world performance under different soils, loads, and climates. This expertise drives continuous optimization of part structure, hardness distribution, and material composition, ensuring stable longevity under long-term heavy-duty use.
• Modern Equipment Ensures Consistent Quality: The factory is equipped with high-precision CNC lathes, automated machining centers, forging machines, and multiple heat treatment systems, enabling integrated production from raw blank to finished product. High-precision equipment reduces dimensional errors and improves consistency, maintaining uniform quality even for large-scale production to meet global customer demands.
• High-Standard Materials Ensure Durability: GFM uses only high-strength alloy and wear-resistant steel, sourced from long-term collaborations with large steel mills to ensure material stability. These materials offer excellent toughness and impact resistance, preventing early wear or breakage due to inconsistent steel composition, ensuring every bulldozer part performs reliably under heavy loads.
• Complete Heat Treatment and Rigorous Craftsmanship: Each component undergoes forging/casting, quenching, carburizing, and precision machining. Heat treatment is monitored by professional engineers to balance hardness depth, surface strength, and core toughness, giving products longer lifespan under high-impact, high-wear conditions.
• Professional Engineering Team and Strict QC: Our engineering team averages over 10 years of experience, familiar with undercarriage structure and lifespan analysis. The QC team performs full-process inspections—including hardness, dimensions, metallography, fatigue, and wear testing. All track group, chain, and roller components must pass high-standard tests before shipment to ensure reliability and durability.
• Comprehensive Product Line Compatible with Major Brands: GFM’s product line covers chains, chain links, carrier rollers, idlers, sprockets, track shoes, and complete track group assemblies. Products are compatible with major brands including Caterpillar, Komatsu, Hitachi, Kobelco, Doosan, Volvo, and Shantui, providing global customers with a comprehensive, one-stop undercarriage solution.
