Import Ball Bearing — Buy in Bulk from Supplier in China

Ningbo Haishu Nide International Co., Ltd supplies deep groove ball bearings and tapered roller bearings from Ningbo, Zhejiang, with an annual production capacity of 150 million pieces stated in their profile. The bearings are manufactured from alloy steel with precision-ground raceways and hardened steel balls, designed to accommodate radial and combined loads depending on the variant selected. Standard deep groove designs suit moderate radial loads and axial loads in both directions, while tapered roller configurations handle higher combined load scenarios with separable inner and outer ring assemblies.

The steel grades used are typically 52100 chrome steel (AISI/SAE) for standard applications, with martensitic or bainitic heat treatment to achieve 60-65 HRC surface hardness on raceways and rolling elements. Ceramic silicon nitride (Si3N4) ball options are available for high-speed, corrosive, or non-magnetic environments. Standard shield and seal variants include Z (single metal shield), 2Z (double shield), RS (single rubber seal), and 2RS (double rubber seal), with nitrile rubber (NBR) or fluoroelastomer (FKM) depending on the temperature and chemical exposure profile. Lubrication options range from standard mineral oil greases to synthetic polyurea or lithium complex greases for extended service intervals.

These bearings find application in electric motors, gearboxes, conveyor systems, agricultural equipment, and automotive wheel hubs where rotational precision and fatigue life are critical. Buyers in the power transmission and general machinery sectors source from Ningbo due to the region's concentration of precision bearing manufacturers and port logistics infrastructure. Import terms referenced include FOB and CIF, though exact Incoterms, MOQ, and lead time should be confirmed directly with the supplier given the zero percent response rate recorded.

Ningbo Haishu Nide International Co., Ltd is located at 1301, No.48 Daliang Street, Haishu District, Ningbo 315010, Zhejiang, placing it within one of China's primary bearing manufacturing and export clusters. The supplier is classified as an imported-tier account with a harbor trust tier, indicating platform-level data integration without additional verification badges. The response rate is recorded at 0.00 percent with zero average response hours, which buyers should note when planning procurement timelines and communication expectations. The company profile does not disclose year of establishment, registered capital, employee count, factory ownership status, or specific quality management system certifications.

The listing emphasises precision manufacturing and quality control, referencing ISO and SGS certifications without specifying certificate numbers, scope, or accreditation bodies. Buyers should request copies of current ISO 9001 quality management system certificates, ISO/TS 16949 automotive sector certifications if applicable, and specific SGS test reports with batch numbers and test dates. The supplier's product range focuses on deep groove and tapered roller bearings with flexible MOQ positioning, though exact minimum order quantities are not stated and must be confirmed directly. No client references, export market experience, or in-house testing capability details are provided in the source material.
