Import Bearing — Buy in wholesale FOB from Supplier in China

Jiangyin Giansun High Precision Mechanical Components Co., Ltd manufactures precision bearings from GCr15 / SAE 52100 chrome steel as standard, with optional 440C or 304 stainless steel for corrosion-resistant applications. The product range encompasses ball bearings, deep groove ball bearings, and roller bearings with bore sizes spanning multiple standard dimensions, engineered to meet ISO and ABEC precision standards. The chrome steel variant provides through-hardened raceways with typical fatigue life ratings governed by ISO 281 calculation methods, while stainless options address environments involving moisture, mild chemicals, or washdown procedures. Source data indicates precision engineering for minimal noise and vibration, with wide temperature tolerance for diverse operational environments.

Material selection between阶段性的决定: GCr15 (Chinese equivalent of AISI 52100) offers standard bearing performance with established heat treatment protocols and cost efficiency; 440C martensitic stainless steel provides superior corrosion resistance with slightly reduced hardness and fatigue life compared to chrome steel; 304 austenitic stainless steel delivers excellent general corrosion resistance but lower hardness, limiting load capacity in heavy-duty applications. The ABEC (Annular Bearing Engineers Committee) precision grades referenced typically range from ABEC-1 through ABEC-7, with higher grades specifying tighter tolerances for bore, outer diameter, width, radial runout, and raceway geometry. Cage designs vary by application, with pressed steel cages for general duty, machined brass for higher speed or temperature, and polymer cages for special requirements. Internal geometry including contact angle, osculation, and ball complement is optimised per bearing type to balance load capacity, speed capability, and operating noise.

Target sectors include automotive OEM and aftermarket, agricultural machinery, general industrial equipment, and aerospace applications where rotating component reliability affects system availability. The supplier positions for global B2B procurement and OEM supply chain integration, with rust-inhibiting export packaging mentioned for ocean freight protection. Payment options referenced include T/T and L/C, with FOB or CIF shipping terms negotiable. No specific MOQ, price band, or lead time is provided in source data, requiring direct confirmation. Certification claims of ISO and SGS appear in materials; importers should verify current validity and scope before reliance. Response metrics are unrecorded, so initial enquiry response time serves as an early supplier evaluation criterion.

Jiangyin Giansun High Precision Mechanical Components Co., Ltd operates from #19 West Yumen Road, Zhouzhuang Town, Wuxi 214434, Jiangsu Province, China. Wuxi and the surrounding Jiangyin area form part of China's concentrated precision bearing manufacturing cluster, with established supply chains for bearing steel, grinding spindles, and metrology equipment. The supplier holds both imported supplier tier and harbour trust tier designations, suggesting some cross-border trade experience alongside baseline verification, though a 0.00% response rate indicates no platform-mediated communication history. Buyers should use direct channels for initial contact.

The company's product positioning emphasises high-precision mechanical components with multi-material capability (chrome and stainless steels) and custom design availability for unique applications. No founding date, employee count, annual revenue, production floor area, or named client references appear in available profile data. The dual material strategy (standard chrome steel plus corrosion-resistant variants) suggests target market segmentation between cost-sensitive general industry and premium applications requiring environmental resistance. Prospective buyers should request facility audit reports or third-party verification to assess manufacturing capability against precision claims, particularly for ABEC-5 and finer tolerance classes where specialised grinding and inspection equipment is essential.
