Gearbox Output Flange Plate F99900-7

truck parts Gearbox Output flange plate F99900-7

Core Features & Advantages

• Forged Alloy Steel Structure: Made of high-quality alloy steel via precision die forging, followed by quenching and tempering processes. It delivers excellent tensile strength and impact toughness, capable of withstanding high peak torque loads without deformation.​

• Micron-Level Precision Machining: Processed by CNC five-axis equipment, ensuring ultra-high accuracy on key mating surfaces. This achieves a zero-clearance fit with the gearbox output shaft, eliminating wear caused by vibration and fluctuations in torque transmission.​

• Stress-Optimized Design: Structural modeling optimized through finite element analysis, with rational thickness distribution and fillet transitions. This significantly reduces the risk of fatigue failure compared to conventional flat flange plates.​

• Dual Anti-Corrosion Protection: Surface treated with electrophoretic coating and a passivation layer, providing strong resistance to rust and corrosion. It performs reliably in humid, dusty, and coastal environments.​

• Plug-and-Play Installation: Pre-drilled mounting holes aligned with OE standards, compatible with standard bolts. This shortens installation time considerably and eliminates the need for on-site machining or modifications.​

• Integrated Sealing Groove: Features a precision-machined sealing groove that fits standard oil seals. It effectively prevents leakage of lubricating oil and blocks external contaminants (like dust and water) from entering the transmission interface.
