Import Ball Bearing — Buy in wholesale FOB from Supplier in China

Top Machinery And Equipment (Zhengzhou) Ltd. supplies deep-groove ball bearings in series 600, 6000, 6200, 6300, 6400, 1200, 1300, 16000 and 61000, configured as open, ZZ shielded, or 2RS sealed variants. The bearing rings and balls are machined from high-carbon chromium chrome steel grade GCr15, equivalent to AISI 52100, a standard material for industrial-grade rolling bearings. Hardened raceways and controlled sphericity give these units the dimensional stability needed for electric motors, pumps, and conveyor systems running at moderate speeds and loads. The supplier is based on Huanghe Road in Zhengzhou, Henan Province, and holds a harbor trust tier with no recorded response data.

GCr15 / AISI 52100 offers a typical hardness of 60-65 HRC after quenching and tempering, with chromium content around 1.30-1.65 percent providing wear resistance and fatigue life. Stainless steel variants are offered for corrosion-prone environments, though the exact grade is not specified in the source listing. Open bearings allow maximum grease choice and relubrication access, ZZ shields keep coarse contaminants out while limiting speed penalty, and 2RS lip seals retain lubricant and exclude fine dust. Standard cage materials are typically pressed steel or brass, depending on series and bore size. Internal clearance groups are not stated but should be confirmed for applications with tight shaft or housing fits.

These bearings serve OEM and aftermarket demand in automotive wheel hubs, agricultural machinery, HVAC blowers, and general industrial gearboxes. Importers should verify the exact series, bore diameter, and seal configuration against their equipment manuals, as cross-referencing between metric and inch-series housings is not automatic. The supplier notes export packaging in reinforced cartons or wooden crates with rust inhibitor protection, though specific VCI paper or desiccant specifications are not given. Buyers should request a certificate of material compliance or mill test report for critical applications, and confirm minimum order quantities and lead times directly with Top Machinery And Equipment (Zhengzhou) Ltd.

Top Machinery And Equipment (Zhengzhou) Ltd. is located on Huanghe Road in Zhengzhou, the capital of Henan Province in central China. The supplier holds a harbor trust tier, which indicates a baseline level of platform verification, though the response rate is listed at 0.00 percent with zero average response hours recorded. The listing provides a product-focused description with series and configuration detail but does not state year of establishment, factory floor area, employee count, or annual output figures. No ISO certificates, laboratory accreditations, or major client names are mentioned.

The company's address places it within Zhengzhou's industrial belt, a region with established metallurgical and machinery manufacturing infrastructure. Buyers should note that the absence of response data means direct enquiry is the only way to confirm stock availability, production lead times, and the exact stainless steel grade if corrosion-resistant variants are required. The listing does not indicate whether the supplier is a manufacturer, trading company, or hybrid operation, so ownership of heat-treatment and grinding capabilities should be clarified during due diligence.
