II. Quality and Performance Guarantee
Material & Craftsmanship Core components are made of QT450-10 ductile iron (tensile strength ≥450 MPa) and 40Cr alloy steel, undergoing precision casting, CNC turning (processing accuracy ±0.01 mm), induction hardening (HRC 58–62), phosphating treatment (rust resistance ≥ Grade 8), and other processes. Equipped with automated production lines, the annual output reaches 50,000 units, supporting large-scale procurement.
Quality Inspection Three quality grades are available:
Genuine: Original parts complying with Sinotruk original technical specifications
OEM Grade: Produced with reference to original standards, cost-effective choice
High-quality Aftermarket: High-quality replacement parts meeting basic usage needs
The factory has passed ISO9001 quality system certification. Core inspection items include dimensional accuracy, air tightness, dynamic balance, and high–low temperature stability. Each product is marked with a production serial number, enabling basic batch traceability.
Service Life Under normal working conditions:
Genuine: ≥800,000 km / 3 years
OEM Grade: ≥600,000 km / 2.5 years
High-quality Aftermarket: ≥400,000 km / 2 years
Optimized heat dissipation structure improves efficiency by 15%, and nano-coated piston rings improve wear resistance by 30%, reducing the failure rate by over 30% compared to ordinary products, even in harsh environments such as deserts, cold regions, and mining areas.
