Import Bearings — Buy in wholesale FOB from Supplier in China

Shanghai Sxd Precision Bearing Production. manufactures precision ball bearings, roller bearings, flange bearings, thin section bearings, hybrid ceramic bearings, and dental bearings from its facility in Shanghai's Pudong New Area. The bearings use chrome steel (GCr15), stainless steel 440C, or hybrid ceramic constructions with ZrO2 or Si3N4 balls, serving dental, automotive, and industrial equipment sectors. The product line spans standard precision bearings through specialised configurations for vacuum, magnetic, low-temperature, and corrosion-resistant environments.

The chrome steel GCr15 variant, equivalent to AISI 52100, offers standard hardness of 60-65 HRC and is the most common material for general industrial applications requiring fatigue resistance and dimensional stability. Stainless steel 440C provides enhanced corrosion resistance with typical hardness of 58-60 HRC, suitable for medical, food processing, and marine environments where moisture or chemical exposure occurs. Hybrid ceramic bearings combine steel rings with ceramic balls, reducing centrifugal force and enabling higher rotational speeds with lower thermal expansion; typical ceramic ball materials are zirconia (ZrO2) for cost-sensitive applications and silicon nitride (Si3N4) for maximum performance in spindles and turbo machinery.

Buyers in the dental, automotive, and precision machinery sectors source these bearings for applications ranging from high-speed handpieces to vehicle powertrains and automation spindles. ABEC and ISO precision grades determine dimensional tolerances and running accuracy, with higher grades required for dental and aerospace applications. Standard packaging is industrial cartons, though specific carton quantities, pallet configurations, and minimum order quantities are not stated in the listing and should be confirmed directly with the supplier. Import orders typically require clarification of incoterms, certificate of origin, and material test reports for regulated industries.

Shanghai Sxd Precision Bearing Production. operates from Building 6, No.25 Hangdu Road, Hangtou Town, Pudong New Area, Shanghai, 201316, China. The company holds a harbor trust tier designation, which indicates a baseline marketplace verification status without additional audited credentials. The response rate is recorded at 0.00 percent with an average response time of zero hours, suggesting that direct communication channels may be limited or that the supplier has not engaged with recent buyer inquiries through the platform interface. Buyers should test responsiveness through multiple contact methods before relying on this channel for time-sensitive procurement.

The supplier's stated scope covers precision ball bearings, roller bearings, flange bearings, thin section bearings, hybrid ceramic bearings, and dental bearings, with material options spanning chrome steel, stainless steel, and ceramic ball configurations. The custom specification references ABEC and ISO precision standards and global shipping capability, but no specific factory certifications, production capacity figures, export license details, or client references are provided. The source description emphasises ZrO2 and Si3N4 ceramic materials and dental bearing specialisation, which may indicate technical focus areas worth exploring during supplier qualification. Buyers should request quality management system certificates, material test reports, and sample bearing dimensional inspection data before placing volume orders.
