Import Bearing — Buy in wholesale FOB from Supplier in China

Ningbo Xinhao Hardware Tools Factory produces ball, roller, and unit bearing configurations from chrome steel GCr15 (AISI 52100), stainless steel 440C and 304, and carbon steel with polyamide cages. The bearings are engineered for high-load applications across machinery, automotive, and manufacturing sectors, with dimensional accuracy governed by ISO and ABEC standards. Standard configurations include deep groove ball bearings, antifriction bearings, and bearing units for rotating machinery support.

Chrome steel GCr15, the most common material in this range, is a through-hardening grade with 1.3-1.6% chromium content, offering typical hardness of 60-64 HRC after heat treatment and excellent fatigue resistance under rolling contact. Stainless steel 440C provides corrosion resistance for humid or washdown environments, though at lower load capacity than GCr15; 304 grade offers superior corrosion resistance but reduced hardness for lighter-duty applications. Polyamide cages reduce weight and permit higher speeds than brass or steel alternatives, though they degrade above 120 degrees Celsius in continuous operation.

Buyers span OEM equipment manufacturers, aftermarket spare parts distributors, and industrial maintenance operations. Applications include conveyor systems, electric motors, gearboxes, pumps, and high-speed spindles. The factory is located in Ningbo's Beilun Industrial Zone, a major port and manufacturing cluster in Zhejiang Province. Buyers should confirm exact load ratings, lubrication requirements, and sealing configurations directly with the supplier, as these determine suitability for specific operating conditions.

Ningbo Xinhao Hardware Tools Factory operates from No.1 Beilun Industrial Zone in Ningbo, Zhejiang Province, postal code 321313. The facility is situated in one of China's major port-industrial clusters, with Ningbo-Zhoushan Port handling significant container throughput that supports export-oriented manufacturing. The supplier's trust tier is classified as harbor, and the response rate stands at 0.00 with zero average response hours recorded. This indicates no verified interaction data is available through the platform, so buyers must initiate direct contact to assess communication reliability and technical support capability.

The listing describes the factory as a bearing manufacturer serving machinery, automotive, and aerospace sectors with OEM and aftermarket supply. The product range emphasises precision-engineered components with ISO and ABEC compliance claims. No verified certification documents, production capacity figures, employee count, year of establishment, or named client references appear in the available profile data. Buyers should request factory audit reports, quality management system certificates, and reference customers to validate production capability and quality control processes before committing to orders.
