1629389 Volvo Towing Jaw | ISO 16047 & ISO 9227-Certified Multi-OE Trailer Coupling Interface for VOLVO Trucks
1629389 Volvo Towing Jaw | FH/FM Series Trailer Coupling Mechanism
Engineered for 1993-2021 commercial towing operations across VOLVO FM12 and FH16 series, the 1629389 towing jaw features forged alloy steel construction with ISO 3584-compliant dimensions for 20442050 replacements. Precision-machined surfaces ensure ±0.5mm tolerance in FM9 fifth wheel assemblies. Hardened pivot pins withstand 35-ton vertical loads on FM7 chassis configurations. Corrosion-resistant coating meets EN 10130 standards for 20583303 cross-compatibility. Laser-etched identification maintains traceability throughout 20-year service cycles.
Technical Specifications: 1629389 Coupling Jaw
42CrMo4 steel alloy achieves 950MPa yield strength with HRC 38-42 surface hardness. CNC-turned bearing surfaces maintain Ra 1.6μm finish for FM10 trailer connections. Zinc-nickel plating provides 500h salt spray resistance per ASTM B117 standards. Load-rated safety latch meets ECE R55 revision 4 requirements.
