Import Bronze Bushing — Buy in wholesale FOB from Supplier in China

This bronze bushing is a plain bearing component machined from a high-density copper alloy, intended for load-bearing applications in industrial machinery where low friction and dimensional stability are required. The supplier lists the material as a copper alloy formulation with surface treatment applied to extend service life, though the exact alloy designation (such as CuSn6, CuSn8, or CuZn39Pb3) is not stated in the listing data. Dimensions are offered in multiple sizes with claimed precise tolerances for interference fits, but the buyer must request the specific dimensional envelope and tolerance class for their shaft and housing requirements.

In bronze bushing manufacture, the copper alloy typically contains tin as the primary alloying element to improve hardness and wear resistance, with phosphorus or zinc additions possible depending on the grade. Standard bronze bearing alloys include leaded tin bronze for improved machinability and aluminium bronze for higher strength in corrosive environments. The surface treatment referenced may involve tumbling, lapping, or a protective oil film, though the supplier does not specify which method is used. Buyers should verify whether the alloy is a continuously cast or centrifugally cast blank, as this affects the material density and freedom from porosity in the finished bushing.

Primary applications include gearboxes, electric motor housings, agricultural equipment, and general industrial machinery where rotating shafts require support with minimal lubrication maintenance. The bushing suits buyers in automotive aftermarket, OEM equipment manufacturing, and heavy machinery repair sectors. Trade terms mentioned in the source include FOB and CIF as possible Incoterms, but the actual offered terms, minimum order quantities, and pricing must be confirmed directly with Xinxiang Haishan Machinery. The supplier carries a harbor trust tier and shows zero percent response rate with zero average response hours on record, so buyers should establish direct communication channels before relying on quoted availability.

Xinxiang Haishan Machinery Co., Ltd. is located at No. 66 Of Chengbei Street, Hui County, Xinxiang, Henan Province, China, with postal code 456300. The supplier carries a harbor trust tier and is classified as an imported supplier type on the platform. The listing shows a zero percent response rate and zero average response hours, which indicates no response data is currently recorded. No information about factory size, year of establishment, employee count, or annual revenue is present in the available profile data.

The company lists bronze bushings among its product offerings, positioning itself as a machined components supplier serving industrial machinery markets. The source description references ISO and SGS certifications, though the listing does not provide certificate numbers, scopes, or validity dates that a buyer could verify. Buyers should request copies of current quality management system certificates and any material test reports directly from the supplier before placing orders. The supplier's physical address in Henan Province places it inland in central China, with export logistics likely routing through Qingdao, Tianjin, or Shanghai ports.
