The 679-ZZ is a specialized thin-section miniature ball bearing designed for high-precision assemblies where radial space is limited but high performance is essential. Featuring dual non-contact metal shields (ZZ), this 9×14×4.5 mm component excels in reducing rotational friction while maintaining a streamlined profile. The rigid steel shields effectively prevent the ingress of dry contaminants and ensure that the high-speed internal lubrication remains distributed across the raceways, making it an ideal choice for compact motors and sensitive electronic devices.
