Import Best Selling Copper Bearing Bushing — Buy in wholesale FOB from Supplier in China

Xinxiang Haishan Machinery Co., Ltd. manufactures copper bearing bushings from high-density copper alloy strip for heavy-duty industrial applications. The bushings are precision-machined to achieve dimensional accuracy and specified surface finish standards for use in machinery, pumps, and automotive assemblies. The material composition centres on a high-density copper alloy, delivering thermal conductivity and wear resistance in high-load, high-speed environments. The supplier targets OEM and aftermarket replacement markets globally, though no specific dimensional range, tolerance class, or alloy designation such as CuSn10 or CuPb10Sn10 is stated in the source data. Buyers should request the exact alloy composition and hardness values to match application requirements.

Copper alloy bushings in this category are typically produced by centrifugal casting or continuous casting followed by precision machining to achieve bore tolerances in the IT7 to IT8 range. Surface roughness Ra values of 0.8 to 3.2 micrometres are common for bearing surfaces, with oil grooves machined in for lubrication retention in high-speed spindles or reciprocating pump applications. The high-density alloy strip referenced suggests a wrought or sintered structure rather than cast, which may offer finer grain structure and more consistent mechanical properties. Thermal conductivity for such alloys typically ranges from 50 to 80 W/(m·K), depending on tin or lead content, while hardness commonly falls between 80 and 120 HB for bearing bronze grades.

Primary applications include automotive manufacturing, heavy machinery, construction equipment, and general industrial equipment where sliding bearing surfaces must withstand cyclic loading. Buyers span OEMs seeking volume production runs and maintenance organisations requiring replacement components. The supplier's address in Hui County, Xinxiang, places it within Henan province's established machinery manufacturing belt. Trade specifics, including MOQ, price bands, lead times, and Incoterms, are not specified in the listing and must be confirmed directly with Xinxiang Haishan Machinery. The supplier carries a harbor trust tier with zero recorded response rate, which buyers should factor into communication planning.

Xinxiang Haishan Machinery Co., Ltd. is located at No. 66 Chengbei Street, Hui County, Xinxiang city, postal code 456300, in Henan province, China. The supplier carries a harbor trust tier and an imported supplier tier classification, indicating it has undergone some level of platform verification. Its response rate is recorded at 0.00% with zero average response hours, which suggests either a new listing, limited platform engagement, or data capture issues. Buyers should anticipate potential delays in initial communication and consider using multiple contact channels.

The company profile does not state establishment year, factory size, annual output, employee count, revenue, export markets served, or specific quality certifications held. The source description mentions ISO and SGS in a generic third-person reference, but these are not confirmed as held by this supplier and should not be assumed. Buyers must request copies of actual quality management system certificates, material test reports, and dimensional inspection records directly. The address in Hui County places the company in a region with historical concentration in machinery parts manufacturing, though this does not independently guarantee production capability.
