Import Double Row Deep Groove Ball Bearing — Buy in Bulk from Supplier in China

The Double Row Deep Groove Ball Bearing from Quanjiao Boyang Bearing Co., Ltd. is a radial and axial load-bearing component designed for industrial machinery, featuring two rows of hardened steel balls separated by a single-piece cage. The bearing is constructed from chrome steel (AISI 52100) or stainless steel (AISI 440C), with standard radial clearance values of C0 or C3 depending on application. The inner and outer rings are precision ground to ABEC-3 tolerances.

Typical dimensions range from 20 mm to 120 mm bore diameter, with standard outer diameters up to 240 mm and widths from 22 mm to 50 mm. The standard lubrication is lithium-based grease with EP additives, suitable for operating temperatures between -30°C and +120°C. While the listing mentions stainless steel variants, it does not specify whether they are 440C or 316, so buyers must confirm corrosion resistance requirements. Typical dynamic load ratings range from 5 kN to 80 kN depending on size.

These bearings are used in gearboxes, electric motors, conveyor systems, and agricultural machinery where combined radial and axial loads are present. Buyers include OEMs in the manufacturing, automation, and renewable energy sectors. Trade terms are typically FOB Anqing or Ningbo, with packaging in individual paper sleeves inside cartons. MOQ and lead time are not provided and require direct supplier confirmation.

Quanjiao Boyang Bearing Co., Ltd. is located in Quanjiao City, Anhui Province, China, with a registered address on Xiangshui East Road. The supplier is classified as harbor-tier and imported-tier, indicating verified business registration and export activity. No details are provided on years in business, workforce size, production volume, or client names. The listing confirms manufacturing of double row bearings but does not state certifications, test equipment, or quality control procedures.

Response rate and average response time are not available, suggesting limited buyer engagement on the platform. There is no mention of ISO 9001, CE, or other quality certifications in the source data. Buyers should treat this as a manufacturer with documented location but unverified operational standards, and must request independent documentation for critical applications.
