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 CAT 345 track chain plays a vital role in your machine’s undercarriage. It connects the track shoes, guides movement, and transfers power from the sprocket to the ground. With the weight and torque of a 45-ton excavator, your track chain must perform without fail — ensuring traction, stability, and long operating life.
Whether you're operating on gravel, slopes, demolition debris, or clay-heavy job sites, our CAT 345 chain ensures excellent guidance and track alignment while resisting deformation, cracking, or premature wear.
Advanced Manufacturing Process for CAT 345 Chain
To ensure strength and consistency, we follow a multi-step production workflow:
- Link Forging – High-strength alloy steel links are forged to achieve superior toughness and integrity.
- Heat Treatment – Pins and bushings are induction hardened to HRC 55–60, forming a tough outer shell and wear-resistant surface.
- Precision Machining – CNC machines are used to control pitch accuracy, bushing diameter, and surface finish.
- Assembly & Pin Pressing – Components are tightly assembled to reduce internal clearance and ensure stable rotation.
- Surface Coating – Anti-rust painting or black oxide finish improves corrosion resistance and visual consistency.
Highlighting the Process
Below are actual product photos from our production facility, reflecting our manufacturing quality:
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 Specifications and Technical Strength
The CAT 345 chain components are made from selected high-performance materials:
- Track Links: 40Mn2 or 35MnB forged steel
- Pins & Bushings: 40Cr hardened alloy
- Surface Hardness: HRC 52–58
- Core Toughness: Preserved through differential heat treatment
- Pitch Size: 260mm (standard for CAT 345 class)
This combination of high hardness and internal toughness helps the chain resist impact, twisting, and long-term fatigue stress.
