Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track link—also known as the track chain assembly—is a fundamental part of the excavator’s undercarriage system. It serves as the structural backbone that connects each track shoe, enabling the entire track to move in unison as the machine advances or reverses. In the case of the Caterpillar E70B, the track chain plays a crucial role in maintaining proper alignment, distributing weight evenly, and transferring engine power efficiently to the ground.
A well-built track chain helps the excavator traverse rough, uneven, or sloped terrains with enhanced stability. It ensures consistent track tension, minimizes lateral slippage, and absorbs the high stress loads generated during digging, grading, climbing, and pivoting. Whether operating in soft soil, rocky landscapes, or urban construction zones, a durable and correctly fitted chain directly influences the machine’s productivity, fuel efficiency, and component longevity.
Material Selection & Heat Treatment Process
Each link in the E70B track chain is made from high-strength alloy steel such as 35Mn or 40MnB. These links are forged and precision-machined to ensure dimensional consistency.
After machining, they undergo deep induction hardening (HRC 50–58) on the bushing and link surfaces to resist wear, bending, and impact during operation.
The mating pins are also hardened and ground to prevent seizure and improve service intervals, while the internal sealing system helps prevent contamination by dust, sand, or mud.
Track Chain Production Process
Track Link Forging & Machining
The raw track links are forged into form, then machined to ensure uniform pitch and hole alignment. Precision is essential for proper sprocket and bushing engagement.
Pin and Bushing
Hardened pins are inserted between the links to create a flexible, load-bearing chain. The sealing system prevents grease leakage and contaminant ingress.
Painting & Surface Coating
After assembly, the entire chain is cleaned and painted with industrial-grade coatings to protect against rust, humidity, and chemical corrosion on job sites.
Final Inspection & Packaging
Before shipping, the chains undergo dimensional checks and torque verification. Chains are then packed securely on wooden pallets or steel frames to avoid deformation.
