Product Specifications Table

To ensure complete matching with original equipment and achieve seamless replacement, every track chain assembly of GFM adopts rigorous dimensional tolerance control and standardized production processes. Buyers can quickly confirm component applicability by checking parameters, thereby significantly reducing on-site installation and equipment downtime maintenance time costs.

The above physical specifications are all precisely ground and can be seamlessly assembled onto the Komatsu PC300-6 excavator undercarriage frame. High-specification material selection and consistent geometric tolerances ensure that this track chain assembly can exert optimal mechanical performance across various work sites.

Product Advantages

The track chain assembly produced by GFM strictly follows industrial-grade standardized forging and heat treatment processes, specifically designed to handle various high-wear and heavy-load harsh working conditions. We ensure longer product operating cycles by enhancing material mechanical properties and structural sealability.

• High-Standard Compatibility: The product is manufactured fully in accordance with original OEM dimensional precision, seamlessly matching the Komatsu PC300-6 excavator undercarriage system without requiring modification.
• High-Strength Wear-Resistant Material: Selected premium 35MnB boron steel possesses extremely high tensile strength and impact fatigue resistance after deep induction quenching, preventing breakage.
• Deep Quenching Extends Lifespan: The track link rail surface hardness reaches HRC 52–58, with an effective hardened layer depth maintained at 8mm–12mm, significantly increasing wear resistance by over 35%.
• Superior Long-Lasting Seal Structure: Utilizes high-performance double-lip polyurethane seal rings resistant to high and low temperatures along with pre-injected long-lasting grease, effectively blocking mud and sand intrusion and reducing wear on internal pins and bushings.

Relying on these comprehensive performance advantages, equipment operators can maintain efficient operation in complex terrains. This not only reduces mechanical failure rates, but also saves long-term undercarriage component replacement expenses for engineering projects.
