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 E320 track chain forms the central mechanical linkage of your undercarriage system. Its primary role is to connect and guide the track shoes, ensuring consistent travel over all types of ground. This chain not only carries the machine’s weight but also transmits power from the sprocket to the ground, allowing the E320 to dig, climb, and operate smoothly under load. Its durability directly affects track alignment, traction, and fuel efficiency.
Optimized Manufacturing Process
Every E320 chain undergoes a carefully controlled production process to ensure long-lasting performance:
- Forged Track Links: High-strength alloy steel is used to forge each link for superior toughness.
- Heat-Treated Pins & Bushings: Deep induction hardening improves wear resistance and shock absorption.
- CNC Machining: Ensures precision pitch (link-to-link distance) and bushing concentricity for low friction and smooth operation.
- Lubricated or Dry Sealed Options: Available in both greased (sealed & lubricated) or dry variants depending on your project needs.
- Surface Protection: Final coating or painting prevents rust and prolongs shelf and service life.
Highlighting the Process
We provide actual production visuals to give you transparency and confidence:
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.
Material Strength & Hardness
The chain’s core components—links, pins, and bushings—are crafted from premium steel grades like 35MnB or 40Mn2. These are heat-treated to achieve:
Outer surface hardness: HRC 52–58 (ideal for resisting abrasion)
Tough inner core: Provides impact resistance to prevent cracking
Extended lifespan: Even under high loads, continuous pivoting, or rocky ground conditions
