The 6902-ZZ is a Double Metal-Shielded Ultra-Thin Series Deep Groove Ball Bearing engineered for applications demanding a slim profile, high rotational speeds, and effective dust protection. Featuring two non-contact steel shields (ZZ) on both sides, it guards against dry contaminants while minimizing friction and heat generation. With a 15 mm bore and an exceptionally low 7 mm cross-section, this bearing is perfectly suited for small motors, precision spindles, and space-constrained devices where reliable high-speed performance is essential.
