As a leading manufacturer and supplier of aftermarket components, Juli Machinery is setting a new benchmark in the global market with superior materials, advanced heat treatment, and precise compatibility with Caterpillar models.

Why Undercarriage Quality Matters

Undercarriage systems are responsible for 50% of the lifetime maintenance costs of tracked equipment. Even minor failures can halt an entire operation. Key components such as track links, rollers, idlers, and sprockets must be able to:

• Withstand constant ground impact and friction
• Maintain dimensional accuracy under heat and pressure
• Resist corrosion, deformation, and fatigue over thousands of hours
• Provide compatibility with OEM configurations and tolerances

Caterpillar excavator undercarriage parts from Juli Machinery are designed with these demands in mind, delivering exceptional durability and cost-efficiency in real-world applications.

Precision Track Links from a Trusted China Source

As an experienced player among china track link producers, Juli Machinery offers a wide selection of forged and machined track link assemblies. Our track chains are:

• Produced from high-manganese steel or boron steel for extreme wear resistance
• Heat-treated and induction hardened to enhance tensile strength
• Compatible with a full range of Caterpillar models, from mini to large excavators
• Available in lubricated or dry pin configurations

Each track link is inspected for pitch tolerance, press-fit, and bushing hardness to ensure consistent field performance, even in rocky, abrasive, or underwater environments.

Track Rollers Engineered to Perform

As one of the trusted track roller factories in China, Juli Machinery delivers single and double flange track rollers that operate under extreme load conditions. Our rollers are:

• Designed with deep-hardened surfaces for longer rolling life
• Fitted with high-precision seals to resist oil leakage and contamination
• CNC-machined to guarantee concentricity and consistent load distribution
• Customizable with various flange profiles, bushing materials, and surface finishes

We manufacture rollers compatible not just with Caterpillar excavators but also with other major OEM brands, offering cost-effective, ready-to-install solutions for both aftermarket and production lines.
