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

Deep groove ball bearings from Zhejiang Lanxiang Bearing Co., Ltd. are produced in Hangzhou, Zhejiang, and designed for general industrial use with standard bore diameters from 10mm to 50mm. These bearings are not limited to miniature sizes and include common series such as 6200, 6300, and 6204, suitable for medium-duty motors, pumps, and transmission systems. The design follows DIN 625 and ISO 15 standards for geometry and tolerances.

The rings and balls are made from high-carbon chromium steel, typically 100Cr6 or equivalent, with heat treatment to achieve hardness of 58-62 HRC. Standard cages are stamped steel, though some variants may use brass or polyamide for higher-speed applications. Internal clearance is typically C0, with C3 available on request. Surface finish on raceways is generally Ra 0.4μm, adequate for non-critical applications but not precision-grade.

These bearings are primarily purchased by manufacturers of small to medium electric motors, agricultural machinery, and textile equipment in South Asia and Latin America. Orders are commonly placed in cartons of 50 to 200 pieces, with palletized shipping for bulk orders. Trade terms are typically FOB Ningbo or Shanghai, with lead times of 20 to 30 days. Packaging is described as single box plus carton and pallet, with customization available upon request.

The supplier's philosophy is stated as pursuing quality, but no evidence of quality control processes, test equipment, or inspection protocols is provided in the listing.

There is no mention of manufacturing facilities, in-house heat treatment, or grinding capabilities. The company appears to operate as a trading entity sourcing bearings from local factories, with no indication of direct production. Response metrics show zero response rate and no response time, suggesting limited buyer support. Buyers should treat this as a sourcing intermediary and request samples and test reports before placing bulk orders.
