Premium Miniature Deep Groove Ball Bearings – 602zz/603zz/604zz/605zz Series
Precision-engineered with high-carbon chromium steel for exceptional durability and smooth rotation. Shielded (zz) or rubber-sealed (2rs) options provide dust and moisture resistance.

Mirror-polished raceways and precision-grade balls reduce friction by 30% vs. standard bearings. Heat-treated for load capacity up to 1,200 RPM.
