Import Casting Brass Worm Gear — Buy in wholesale FOB from Supplier in China

The Casting Brass Worm Gear from Xinxiang Haishan Machinery Co., Ltd. is manufactured using leaded brass alloy, typically CuPb6Sn6Zn3, with a density of approximately 8.4 g/cm³. The gear is precision cast to maintain tight tooth profile tolerances, with a standard module range of 1.5 to 4.0 and pressure angles of 14.5° or 20°. Surface finish averages Ra 3.2 µm, suitable for continuous meshing in enclosed gearboxes. These dimensions align with ISO 1328-1:2013 standards for cylindrical gears, ensuring interchangeability in industrial systems.

Brass worm gears are selected for their corrosion resistance and low friction against steel worms, making them ideal for humid or mildly abrasive environments. Unlike steel gears, they do not require external lubrication in low-load applications and offer dampening properties that reduce noise. The casting process allows for internal ribs and mounting bosses to be integrated, reducing assembly complexity. Typical hardness values range from 85 to 110 HB, balancing wear resistance with machinability for post-cast adjustments.

This gear is commonly used in conveyor drive units, packaging machinery, and robotic actuators where smooth torque transmission and minimal backlash are critical. Buyers in the automotive aftermarket, light manufacturing, and automation sectors source this product for replacement and retrofit applications. Packaging is in anti-rust paper with inner plastic wrap and standard export cartons. Trade terms available include FOB Shanghai or CIF destination port. Minimum order quantities are confirmed directly with the supplier, as batch sizes vary by gear module and volume.

Xinxiang Haishan Machinery Co., Ltd. operates from Hui County, Henan Province, and is registered as an exporter of precision brass castings. The company is listed as an imported supplier with harbor trust tier, indicating compliance with export documentation standards. There is no public information on factory size, workforce, or years in operation. The listing confirms production capability for brass worm gears but does not state certifications, client names, or annual output volumes.

The supplier does not provide response metrics, indicating limited direct buyer engagement on the platform. However, the inclusion of a verifiable factory address and product-specific technical description suggests operational legitimacy. Buyers should request sample pieces and inspection reports before placing bulk orders. No claims are made regarding ISO certification, in-house testing labs, or R&D capacity.
