Ningbo Hongtai Bearing Co., Ltd supplies the 6303 deep groove ball bearing with a copper-plated outer ring and a nylon cage. The bearing has a bore of 17 mm, an outer diameter of 47 mm, and a width of 14 mm, designed for smooth rotation and corrosion resistance in demanding environments.
The bearing is constructed from chrome steel (GCr15) with a copper plating on the outer ring, enhancing its durability in humid or corrosive conditions. The nylon cage reduces weight and friction, making it suitable for caster wheel assemblies and industrial handling equipment where quiet operation and low maintenance are priorities.
This model is widely used in OEM manufacturing, maintenance supply, and export trade for machinery, logistics, and material handling applications. Importers should confirm compatibility with their equipment’s load, speed, and environmental conditions, as the copper coating and nylon cage offer specific advantages over standard configurations.

Before ordering, verify the bearing’s material composition, cage type, and plating specifications to ensure they meet your application’s requirements. Request test reports for parameters like hardness, surface finish, and dimensional accuracy to confirm quality standards.
Clarify incoterms (e.g., FOB Ningbo or CIF destination) and packaging options, as bearings are typically shipped in bulk or individual boxes. Confirm lead times, especially for custom quantities, and discuss payment terms to align with your procurement processes.
Inspect a sample for compliance with ISO 281 standards and check for signs of corrosion resistance, smooth rotation, and proper cage alignment. Request documentation such as material certificates, plating thickness reports, and final inspection records to ensure traceability and quality.
