Cummins engine auto parts fan bracket C5625429 in stocked

Built as the critical support for the engine cooling fan, this bracket features a reinforced structural design to endure dynamic loads. The main body is precision-cast from A380 aluminum alloy with internal ribbed reinforcement, achieving a tensile strength of 310MPa and bending strength of 280MPa. It integrates a triangular truss structure at the fan hub mounting area, distributing the 800N radial force from the rotating fan (2100rpm) evenly across the bracket. The mounting flange is thickened to 15mm, enhancing connection stability with the cylinder block. This design prevents bracket deformation or cracking, ensuring the fan maintains a concentric runout of ≤2mm—critical for avoiding airflow turbulence and noise

Engineered to adapt to the high-temperature environment near the engine radiator, the bracket integrates heat dissipation-enhancing features. The outer surface is designed with 24 longitudinal heat-dissipating ribs, increasing the heat dissipation area by 50% and reducing the bracket’s operating temperature by 15℃ compared to non-ribbed designs. The material undergoes a T6 heat treatment process, maintaining structural integrity at continuous operating temperatures up to 120℃ (short-term tolerance up to 150℃). A thermal insulation pad (silicone-based, 3mm thickness) is pre-installed on the flange surface, preventing heat transfer from the cylinder block to the bracket’s mounting bolts—avoiding bolt thermal expansion and loosening

Optimized for long-term reliability in diverse working conditions, the bracket exhibits exceptional corrosion and wear resistance. The entire surface undergoes a two-step protective treatment: first, a chromate-free conversion coating for corrosion priming, followed by a powder coating (80μm thickness) with high weather resistance. This coating passes 2000-hour neutral salt spray testing (ASTM B117) to prevent rust in coastal or saline-alkali areas. The fan hub mounting holes are equipped with stainless steel inserts (304 grade) to resist wear from repeated fan assembly/disassembly. The bracket also resists chemical corrosion from engine oil and coolant, with no performance degradation after 500-hour immersion testing

The fan bracket is designed for efficient installation and long-term cost savings. Pre-drilled mounting holes and precision-machined positioning pins ensure quick alignment with the cylinder block, reducing installation time by 40%—two technicians can complete replacement in 90 minutes. The bracket’s stable performance prevents fan misalignment, avoiding costly issues like radiator damage (repair cost up to $2,000) and engine overheating. As a genuine Cummins part, it eliminates the need for aftermarket modifications, ensuring compatibility with the original cooling system. Backed by a 2-year/250,000km warranty, it reduces unplanned downtime for fleet operators and avoids repeated replacement costs of low-quality brackets
