HELI (CQCTRACK): Your Premier Source for Genuine-Grade Caterpillar Undercarriage Components – Track Bottom Roller Assemblies

As a leading manufacturer and supplier in the global undercarriage industry, HELI (operating under the brand CQCTRACK) specializes in the precision engineering and production of high-performance, interchangeable replacement components for Caterpillar® crawler excavators. Our core expertise lies in delivering durable, reliable, and cost-effective solutions for critical chassis parts, notably including a comprehensive range of Track Bottom Roller (Track Roller) Assemblies.

This page provides a detailed overview of our capability to manufacture and supply replacement Bottom Roller Assemblies compatible with key Caterpillar® part numbers and machine models, serving as an essential resource for equipment owners, fleet managers, and distributors worldwide.

Product Focus: Caterpillar-Compatible Track Bottom Roller Assemblies

The track bottom roller is a fundamental component within the undercarriage system, bearing the machine’s weight and guiding the track chain in motion. It is subjected to immense stress, shock loads, and abrasive wear. Our assemblies are engineered to meet or exceed the original specifications for fit, function, and longevity.

Compatible Part Numbers & Applications:

• Caterpillar® Part Number 1787293: A critical track roller assembly designed for specific mid-to-large size Caterpillar excavator models.
• Caterpillar® Part Number 1231379: A widely used bottom roller component known for its application across several popular excavator series.
• Caterpillar® Part Number 1524128: This part number corresponds to a robust track roller assembly built for demanding operating conditions.
• Compatible Machine Models (Including but not limited to):
  • Caterpillar E345, E349 Excavators: Our rollers for these models are precision-machined to ensure seamless integration and optimal performance, supporting efficient operation in various earthmoving and excavation tasks.

Engineering & Manufacturing Excellence at HELI (CQCTRACK)

Our promise of quality is rooted in a controlled, vertical manufacturing process:

1. Material Science: We utilize high-grade, alloy forged steel for the roller body and shaft, ensuring superior tensile strength and impact resistance. Material composition is strictly analyzed to guarantee optimal hardness and wear characteristics.
2. Precision Machining: Advanced CNC (Computer Numerical Control) machining centers guarantee micron-level accuracy in all critical dimensions—bore size, flange diameters, and sealing surfaces—ensuring perfect interchangeability with OEM components.
3. Heat Treatment: Components undergo controlled carburizing, quenching, and tempering processes. This creates a hardened, wear-resistant exterior surface (typically 58-62 HRC) while maintaining a tough, ductile core to absorb dynamic loads and prevent brittle fracture.
4. Sealing Technology: We integrate premium, multi-layered lip seals and precision bearings. Our sealing systems are engineered to effectively exclude contaminants (dust, mud, slurry) and retain lubrication, significantly extending service life even in extreme environments.
5. Quality Assurance: Every batch undergoes rigorous inspection, including dimensional checks, hardness testing, rotational torque measurement, and pressure testing for seals. Our process is aligned with international quality management standards.
