Volvo fan hub 21924453 plays a key role in fixing and transmitting in the engine cooling system. As the connection hub between the fan and the drive shaft, it not only stably fixes the fan blades but also transmits torque to drive the fan rotation, ensuring that airflow takes away engine heat through the radiator. Its structural strength directly affects the stability of the cooling system, compatible with Volvo FH13, FM460, D13K series engines.
The fan hub is made of high-strength ductile iron or aluminum alloy through precision casting, with a corrosion-resistant surface treatment, temperature resistance range of -40℃ to 180℃, and compressive strength ≥300MPa. It can withstand radial force (≥500N) generated by high-speed fan rotation and continuous vibration impact (15G acceleration level). Its shaft hole fitting accuracy reaches IT6 grade, and the clearance error with the drive shaft is ≤0.03mm, ensuring smooth transmission without jamming, with a normal service life of over 12,000 hours.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. provides both original and aftermarket 21924453 fan hubs. Original products strictly follow Volvo technical specifications, using imported casting technology, suitable for long-distance heavy-duty scenarios with extremely high requirements for transmission stability; Aftermarket products pass 1000-hour durability tests, with key dimensions and mechanical properties reaching over 90% of the original, priced at 55%-65% of the original, suitable for regular maintenance and budget-conscious customers, both with 12-month warranty.
During installation, ensure accurate alignment with the fan and drive shaft, and tighten bolts according to specified torque (35-40N·m recommended) to avoid vibration and abnormal noise caused by eccentricity. We have sufficient inventory, supporting global delivery within 48 hours, and our technical team can provide compatible model inquiry and installation torque guidance.
