Import Bimetal Bearing — Buy in Bulk from Supplier in China

The JF-800 bimetal bearing combines a low-carbon steel backing with a copper alloy surface layer, a design chosen for its ability to handle heavy radial and axial loads while maintaining low friction. The steel provides structural integrity under mechanical stress, while the copper alloy reduces wear and improves heat dissipation, making this bearing suitable for industrial machinery exposed to high temperatures and cyclic loading.

This model is built for environments where standard bearings may fail, such as in construction equipment, conveyor systems, or automotive assemblies. The copper alloy surface is typically graded to ASTM B22 or B274 standards for bronze, offering a typical hardness range of 60 to 80 HRB and a standard operating temperature window of -40°C to 200°C. The bearing’s two-layer construction also resists seizure under boundary lubrication conditions, a common failure mode in high-load applications.

Engineers in automotive, manufacturing, and power generation sectors select this type for its balance of cost and performance in moderate-speed, high-load scenarios. Buyers should confirm compatibility with their shaft and housing tolerances, as the bearing’s inner diameter and outer diameter must match ISO or DIN standards typical for the JF-800 series. The supplier ships from Zhejiang, with MOQ and Incoterms agreed per order, and recommends verifying load ratings against the specific application’s dynamic and static requirements.

Jiashan Yongsheng Bearing Co. Ltd. operates from No.92 Xiangjia Road in the Lize Industrial Zone of Zhejiang Province, China. The company specialises in industrial bearings, with its portfolio including bimetal and composite designs for heavy-duty applications. Its trust tier is classified as harbor, indicating a baseline level of verification for export readiness, though its current response rate to inquiries is recorded at 0.00%.

The supplier’s profile does not disclose production capacity, annual turnover, or client references, and no additional certifications beyond ISO 9001 are listed. Buyers are advised to request updated verification documents, such as material test reports or third-party inspection certificates, to confirm the bearing’s compliance with their technical specifications. The address in Jiashan places the company within a known manufacturing hub for mechanical components, which may offer logistical advantages for bulk shipments.
