Wholesale 72 Pitch Mini Excavator Track Link Assy Factory

El 72 pitch mini excavator conjunto de enlace de oruga is a heavy-duty undercarriage component engineered to transmit driving torque and support machine payload. Although operating under constant ground friction, this link assembly plays a vital role in ensuring machine stability, track tension integrity, and operational efficiency during demanding earthmoving jobs. A premium track link must guarantee precision fitment while delivering long-term safety and high structural reliability under severe working conditions.

• Precision OEM Dimensions: GFM manufactures the 72 pitch conjunto de enlace de oruga in strict compliance with original manufacturer specifications, ensuring seamless alignment with sprockets, bottom rollers, and front idlers. This engineered fit makes field installations fast and effortless, effectively minimizing equipment downtime.
• Superior Hardness & Wear Resistance: Forged from premium 35MnB alloy steel and processed with advanced computer-controlled induction hardening, our rail surfaces achieve a deep hardness depth with surface hardness reaching 48-52 HRC. This offers outstanding resistance to abrasive wear, even in challenging mining, quarry, and heavy construction environments.
• High Impact & Bending Strength: Built for tough digging, the 72 pitch link plates deliver core tensile strength exceeding 1000 MPa after professional heat treatment. It withstands extreme breakout forces and continuous shock loads without bending, cracking, or link plate separation.
• Secure Sealed Pin & Bushing Joint: Paired with high-grade synthetic polyurethane seals and precision ground pins, the assembly retains internal lubricant within the joint cavity. This secure retention prevents pin-and-bushing galling, guarding against premature track pitch extension or costly chain breakage.
• Reduced Maintenance Overhead: The extended wear life of both the forged link plates and internal pin joints significantly lowers replacement frequency. This helps fleet operators cut long-term maintenance costs while maintaining continuous site productivity.

Designed for high performance, the 72 pitch conjunto de enlace de oruga is widely utilized across urban trenching, utility excavation, and landscaping operations. Every batch undergoes rigorous dimensional checks, Rockwell hardness testing, and magnetic particle flaw inspection to meet global quality expectations. To back this exceptional durability, GFM provides a reliable quality warranty of at least 1 year or 2000 operating hours.
