Import Bearing — Buy in Bulk from Supplier in China

Hubei Boying Jinggong Technology Co., Ltd. offers deep groove ball bearings, roller bearings, and additional configurations from their facility in Daye, Hubei Province, China. The bearings are manufactured from steel alloy with precision machining to control radial runout and surface finish. Standard precision grades align with ISO tolerances for general machinery and automotive applications, though buyers should confirm the exact ABEC or DIN grade with the supplier before specifying for high-speed spindles.

The material selection typically includes through-hardened chromium steel (SAE 52100 equivalent) for raceways and rolling elements, with options for stainless variants in corrosive environments. Heat treatment achieves typical hardness of 58-64 HRC on bearing surfaces. Cage materials range from stamped steel to brass or engineered polymers, depending on operating temperature and speed. Sealing options include metal shields (ZZ suffix) and rubber contact seals (2RS), with grease fill volumes calibrated to service intervals. Standard lubricants operate from -30°C to +120°C, with specialty greases available for extended temperature ranges.

These bearings serve automotive drivetrain, general industrial machinery, and construction equipment sectors where contamination resistance and load capacity govern selection. Importers should verify the supplier's current ISO 9001 certificate scope, request material mill certificates for traceability, and confirm whether lot testing includes dimensional inspection and vibration analysis. Packaging is typically industrial carton with rust inhibitor; ocean freight consolidation from Huangshi or transit to Shanghai or Shenzhen port should be discussed with the supplier.

Hubei Boying Jinggong Technology Co., Ltd. is located in Chengui Industrial Park, Xiaoleishan Town, Daye, Hubei Province, with postal code 435100. The supplier's profile indicates an imported-tier classification with harbor trust tier, and the response rate is recorded at 0.00 percent with zero average response hours. These signals suggest limited historical buyer engagement through the platform, so direct communication channels and due diligence are essential before placing orders.

The company positions itself as a manufacturer of bearings for automotive, aerospace, and heavy machinery applications. The source description references ISO and SGS certifications, though buyers must independently verify current certificate validity, scope, and accreditation body. No specific factory size, annual output, or client references are substantiated in the available data. The address places the operation in central China's industrial belt, with access to steel supply chains and inland waterway connections to coastal ports.
