6909 ZZ EZO 45x68x12 Deep Groove Ball Bearing

Design and Construction

The 6909 ZZ EZO 45x68x12 is a compact deep groove ball bearing from the 6900 series, designed to provide increased load capacity while maintaining a space-efficient profile. Compared to thin-section 6800 series bearings, it features a wider cross-section, resulting in improved structural strength and durability.

The ZZ designation indicates double metal shields, which protect the internal components from dust and contaminants while allowing high-speed operation with low friction. Manufactured by EZO Japan, the bearing ensures high precision, smooth raceway finishing, and consistent long-term performance.
