Zhejiang Dongbin Rubber Machine Screw Co., Ltd., based in Zhoushan, China, manufactures the 1200 bearing sleeve, a component specified for use in bearing housings. The listing provides detailed heat treatment and surface finishing data, indicating this is a precision-engineered part for industrial machinery. Key confirmed specifications include a hardness after hardening and tempering of HB240-280, a nitrided hardness of HV850-1000, and a nitrided case depth of 0.45-0.7 mm.
The bearing sleeve is designed to meet demanding operational requirements, evidenced by its nitrided brittleness being less than Grade 1 and a surface roughness of Ra0.4. These values suggest a component built for wear resistance and a precise fit within a bearing housing assembly. The designation '1200' likely refers to a model number or internal part code, common in machinery component catalogues. Typical industry applications for such sleeves include supporting rotating shafts in heavy equipment, pumps, and compressors where reduced friction and high load capacity are critical.
Buyers of this component are typically maintenance engineers, procurement specialists for manufacturing plants, and OEMs sourcing parts for rubber processing or other industrial machinery. The supplier's address in the Shantan Industry Zone of Dinghai District, Zhoushan, places it within a known Chinese industrial manufacturing cluster. Specific pricing, minimum order quantity, and lead time are not listed and must be negotiated directly with the manufacturer to align with project or maintenance schedules.

When sourcing the 1200 bearing sleeve from Zhejiang Dongbin Rubber Machine Screw Co., Ltd., your primary verification step is to obtain the complete technical documentation. Request the material test report (MTR) for the base steel, a detailed dimensional drawing with tolerances, and a certificate confirming the specified hardness, nitrided case depth, and brittleness grades. This paperwork is essential for validating that the component will perform reliably in your specific bearing housing application.
For logistics, determine the most suitable shipping method based on urgency and cost. Given the component's likely weight, sea freight from Ningbo or Shanghai port is standard. Negotiate clear Incoterms, such as FOB or CIF, and ensure the supplier uses appropriate export packaging, such as wooden crates with oil-paper wrapping, to prevent corrosion and damage during transit. Obtain a confirmed production and delivery timeline, factoring in the supplier's current low response rate into your project planning.
Implement a quality check upon receipt. Consider a pre-shipment inspection at the factory in Zhoushan to verify dimensions, surface finish, and hardness on a sample basis before the full order is dispatched. Upon delivery, inspect the sleeves for any transport damage and verify key dimensions against the provided drawings. Maintaining clear records of all specifications and correspondence will facilitate any future re-orders or warranty claims.
