The Nachi 6309ZZ double-shielded radial ball bearing is engineered for high performance in demanding electrical and mechanical applications, featuring a 45 mm bore, 100 mm outer diameter, and 25 mm width for a precise fit in standard machinery. This deep groove ball bearing offers a static load rating of 32,000 N and a dynamic load capacity of 53,000 N, ensuring reliable operation under heavy radial and axial loads. With double metal shields for contamination protection and C3 internal clearance for reduced friction, it supports smooth, quiet rotation at speeds up to 7,000 rpm with grease lubrication. The 6309ZZ is constructed from high-grade steel with a stamped steel cage, providing durability, low maintenance, and extended service life in electric motors, automotive systems, and industrial equipment. Its standardized metric dimensions and shielded design make it a versatile, long-lasting solution for high-speed, high-load environments.
