Deep Groove Ball Bearing
The 623-Z deep groove ball bearing from Nanjing Haning Bearing Manufacturing Co., Ltd. has a 3 mm bore, 10 mm outer diameter, and 4 mm width, constructed from high-carbon chromium steel conforming to G10-G20 grade standards. It supports a dynamic load rating of 0.54 kN and a static load rating of 0.18 kN, with a reference speed of 130,000 r/min and a limiting speed of 80,000 r/min. The shielded design (Z) provides basic protection against dust and contaminants while maintaining low friction for high-speed rotation.
This bearing is manufactured to ISO 15 standard dimensional tolerances, with internal clearance typical for general-purpose applications. The material composition is consistent with industry-standard chrome steel used in precision components, offering good hardness and wear resistance. While the listing does not specify heat treatment or surface finish, these are typically controlled in industrial-grade bearings to ensure consistent performance under cyclic loading. Shielded variants like the 623-Z are preferred in environments where sealing is not critical but contamination control is still desired.
These bearings are commonly used in small electric motors, precision measuring instruments, dental handpieces, and miniature conveyor systems. Buyers include OEM manufacturers of consumer electronics, medical devices, and industrial automation equipment sourcing from China for cost-effective, reliable components. Packaging is typically in bulk or cartons of 500 to 1,000 units, with lead times averaging 2 to 4 weeks for standard orders. Trade terms are typically FOB Nanjing or CIF, with payment via T/T or L/C.

Sourcing Deep Groove Ball Bearing from Nanjing Haning Bearing Manufacturing Co., Ltd. - China Import Guide
Before ordering, verify the bearing’s material grade, load ratings, and shield type match your application. Request a copy of the dimensional drawing and confirm tolerance class (ABEC or ISO) if precision is critical. Ensure the supplier provides batch traceability for the steel, especially if the bearing will be used in regulated industries like medical or aerospace. Do not assume compliance with international standards unless explicitly confirmed in writing.
Lead time for standard orders is typically 2 to 4 weeks, but confirm with the supplier if custom packaging or mixed SKUs are needed. Incoterms are usually FOB Nanjing Port, with payment via 30% advance and 70% against shipping documents. Buyers should clarify whether the supplier handles export documentation, including commercial invoice, packing list, and certificate of origin. Request a test report for load and speed performance if the bearing will operate near its limits.
Conduct incoming inspection using a micrometer to verify bore and outer diameter dimensions. Check for smooth rotation and absence of audible noise or play. Confirm shield integrity and lubricant presence. Request a material certification for the steel grade and ask for a sample batch to test under simulated load. Retain a sample for future comparison. Documentation should include a quality control checklist and a batch number for traceability.
