Worm Gearbox Bronze Worm Wheel from Germany
This phosphor bronze worm wheel meshes with a worm screw in a worm gearbox to achieve high-ratio speed reduction with self-locking capability. It qualifies under HTS 8483.90.50 as a part of gearing and other speed changers for conveyor and hoist systems. High wear resistance suits heavy-duty industrial use.

Import Tips
• Conduct metallurgical analysis certificates to prove bronze content for correct duty rates
• Document thread pitch and helix angle specs to distinguish from general toothed wheels under 8483.40
• Pair with OEM part numbers from gearbox manufacturers for binding ruling requests
