Import Bearing — Buy in wholesale FOB from Supplier in China

J&B Bearing Manufacture Co., Ltd. produces deep groove ball bearings from chrome steel (GCr15 / AISI 52100), stainless steel 440C, and ceramic hybrid configurations at its facility in Nantong, Jiangsu Province, China. The supplier lists multiple model references including Akasaka AH30, DM33, and DM36W, though these appear to represent application or customer series designations rather than standard ISO dimension series. The bearings are engineered for radial and combined radial-axial load capacity with minimised friction coefficients for power transmission and rotating equipment applications.

The chrome steel variant GCr15, equivalent to AISI 52100, is a through-hardening high-carbon chromium steel typical for bearings requiring high fatigue strength and wear resistance, with standard hardness of 60 to 64 HRC after heat treatment. Stainless steel 440C offers improved corrosion resistance at moderate hardness levels, suitable for humid, washdown, or mildly corrosive environments. Ceramic hybrid bearings, typically combining silicon nitride (Si3N4) ceramic balls with steel rings, permit higher peripheral speeds and reduced centrifugal loading, though the exact ceramic grade and ring steel pairing should be confirmed with J&B Bearing Manufacture Co., Ltd.

These bearings serve automotive OEM and after-market channels, industrial machinery builders, and power transmission system integrators. Buyers should specify bore diameter, dynamic and static load ratings, seal configuration, internal clearance, and required tolerance class when requesting quotation. The supplier indicates flexible minimum order quantities, but no confirmed MOQ, pricing, or lead time is stated. Certification claims in the original source are unverified; buyers must independently confirm ISO 9001, IATF 16949, or other applicable quality system credentials directly with J&B Bearing Manufacture Co., Ltd.

J&B Bearing Manufacture Co., Ltd. operates from 10 Yongxin Road, Nantong, Jiangsu, 212400, China. Nantong is a significant manufacturing cluster within the Yangtze River Delta with established bearing production infrastructure and access to Shanghai port logistics. The supplier holds a harbor trust tier classification with a recorded zero percent response rate and no average response time data, suggesting limited or untested inquiry handling through the platform channel. No founding date, registered capital, employee count, or factory floor area is disclosed.

The supplier profile does not confirm ISO 9001, IATF 16949, or other quality management certifications, nor does it name specific OEM customers, export markets served, or annual production capacity. Buyers should conduct due diligence including factory audit, quality system verification, and sample evaluation before committing to volume procurement. The ceramic hybrid and stainless steel product lines indicate some technical breadth, but the depth of in-house manufacturing versus trading should be clarified directly with J&B Bearing Manufacture Co., Ltd.
