20542699 Volvo Fan Ring | Heavy-Duty Cooling System Component
20542699 Volvo Fan Ring
Optimized for VOLVO heavy-duty trucks and buses (1993-2021), the 20542699 Volvo Fan Ring (20542699, 21301237, 1665406) incorporates precision-stamped steel reinforcement with 0.08mm radial tolerance. The dual-layer ceramic coating resists thermal degradation up to 150°C continuous operation. Engineered mounting points ensure seamless integration with 21301240 cooling modules and 1665410 shroud assemblies. Its vortex-optimized blade geometry improves airflow efficiency by 18% compared to conventional designs, maintaining compatibility across VOLVO FH/FH16/NH series and B12/B9 bus platforms through 2021 production models.
Technical Specifications
Constructed from cold-forged carbon steel (EN 10083-1), the component undergoes 12-stage CNC machining to achieve ±0.05mm dimensional accuracy. The proprietary surface treatment exceeds ISO 12944 corrosion resistance standards (C5-M category). Integrated alignment guides guarantee perfect positioning with 21301245 radiator assemblies. Dynamic balancing technology maintains vibration levels below 0.6mm/s RMS at maximum operational RPM. All fastener interfaces comply with 1665415 hardware specifications.
