Import Bearing — Buy in wholesale FOB from Supplier in China

Shanghai Rockwood Bearing Co., Ltd supplies deep groove ball bearings in the 6200 series, manufactured from chrome steel AISI 52100 (GCr15 equivalent) with precision radial and axial load capacity. The deep groove geometry accommodates both radial and axial loads in either direction, with a continuous raceway enabling smooth high-speed rotation. These bearings conform to HS 8482 classification standards, ensuring dimensional interchangeability with global machinery interfaces. The chrome steel construction provides a typical hardness of 60-65 HRC after through-hardening, with operational stability across temperature ranges from approximately -30 degrees C to +150 degrees C for standard configurations.

The AISI 52100 / GCr15 material composition contains 1.3-1.6% chromium, 0.95-1.1% carbon, and manganese allowances that achieve uniform carbide distribution after proper heat treatment. Deep groove ball bearings in this series typically feature steel cage constructions (pressed steel or machined brass depending on variant), with internal clearance groups ranging from C2 through C5 to accommodate varying fit and thermal expansion conditions. Shielded (ZZ) and sealed (2RS) variants are standard industry options for contamination protection, though buyers should confirm available closures directly with Shanghai Rockwood. The raceway groove radius is precisely controlled to approximately 52-56% of ball diameter, optimising contact geometry for load distribution and fatigue life.

Primary applications span electric motors, pumps, conveyors, gearboxes, and auxiliary machinery in automotive, aerospace, and general manufacturing sectors. Buyers include OEMs, maintenance-repair-overhaul (MRO) distributors, and industrial equipment exporters seeking standardised rotating components. Trade terms referenced include FOB and CIF, with flexible minimum order quantities and export-oriented packaging. Response rate data is currently unavailable, so buyers should establish direct communication channels for quotation and lead-time confirmation. Certification claims of ISO and SGS are mentioned in source materials; importers should request current certificate copies and scope of accreditation before placing orders.

Shanghai Rockwood Bearing Co., Ltd is located at No. 1788 Jintong Road, Shanghai 201802, China, placing it within the Yangtze River Delta manufacturing corridor with established logistics infrastructure for industrial component export. The supplier holds a harbour trust tier designation, indicating baseline platform verification, though a response rate of 0.00% and zero average response hours suggest communication data is either unreported or not yet established through the platform channel. Buyers should initiate direct enquiry to assess responsiveness and quotation turnaround.

The company's product focus centres on standardised deep groove ball bearings for general industrial applications, with source materials referencing 6200 series production and flexible order quantities for international buyers. No manufacturing floor details, production capacity figures, year of establishment, or client references are provided in available profile data. Certifications mentioned include ISO and SGS, though buyers must verify current certificate validity, scope, and accreditation body directly with the supplier before relying on these for import compliance or quality assurance.
