Products classified under HTS 8483.90.50.10
Forged Steel Spur Gear Blank
A rough-forged steel blank designed for machining into spur gears used in industrial gearboxes and speed changers. It falls under HTS 8483.90.50.10 as a forged part specifically for gearing elements, before final tooth cutting and finishing. These blanks provide the basic shape and strength required for high-torque transmission applications.
Forged Alloy Steel Helical Gear Blank
Forged from high-strength alloy steel (e.g., 4340), this blank is pre-formed for helical gear production in heavy-duty speed changers and industrial transmissions. Classified under HTS 8483.90.50.10 due to its forged state and specific gearing application before hobbing or grinding. Ideal for angled tooth designs in high-speed machinery.
Forged Camshaft Gear Blank
A forged blank tailored for timing gears on automotive and engine camshafts, part of speed changing mechanisms. HTS 8483.90.50.10 applies as it's a pre-machined forged part for gear boxes and gearing elements. Provides precise lobe positioning for valve timing in internal combustion engines.
Forged Differential Gear Blank
Heavy-duty forged blank for ring and pinion gears in vehicle differentials, functioning as speed changers. Falls under HTS 8483.90.50.10 as a forged part of gear boxes before final gear cutting. Essential for torque distribution in axles and drivetrains.
Forged Wind Turbine Gear Blank
