Why Choose Beijing Silk Road for Your 6D24 Crankshaft Needs

Precision Engineering to OEM Specifications. Beijing Silk Road produces 6D24 crankshafts from forged 42CrMo alloy steel with multi-stage nitriding heat treatment, achieving surface hardness of HRC 58-62. Every journal diameter, fillet radius, and oil gallery position is machined to original Mitsubishi blueprint tolerances. Each unit passes ultrasonic flaw detection, CMM dimensional verification, dynamic balancing to ISO 1940 G6.3, and magnetic particle inspection prior to shipment. The result is a genuine drop-in replacement requiring no on-site modification.

Factory-Direct Wholesale Pricing. As a vertically integrated manufacturer established in 2009, Beijing Silk Road controls every production stage — from raw material procurement through forging, machining, and final inspection.

Quality Inspection Protocol

Every Beijing Silk Road crankshaft undergoes a comprehensive five-stage inspection before release:

1. Ultrasonic Flaw Detection — verifies internal material integrity
2. CMM Dimensional Inspection — confirms all journal diameters and runout tolerances
3. Dynamic Balancing — certified to ISO 1940 G6.3 balance grade
4. Surface Hardness Testing — validates nitriding depth and HRC values
5. Magnetic Particle Inspection — detects surface and near-surface discontinuities

Export Packaging

Each crankshaft is treated with anti-rust VCI (Volatile Corrosion Inhibitor) coating, wrapped in industrial-grade protective film, and secured in a custom-fit export plywood case with high-density foam cushioning. Desiccant packs are included to maintain a moisture-free environment during ocean freight transit. All packaging meets ISPM 15 standards for international timber treatment.
