The 6302-ZZ stands as a highly versatile, dual-metal-shielded single-row radial ball bearing engineered to deliver exceptional performance under elevated operational speeds and steady radial loads. To minimize drag, this model incorporates twin non-contact pressed steel shields (ZZ) that form a precise barrier over the internal mechanics, retaining factory-applied grease and deflecting dust without creating mechanical friction. Featuring standardized metric dimensions—a 15 mm bore, 42 mm outer diameter, and 13 mm width—the 6302-ZZ provides a highly dependable mechanical solution for power tools, electric motors, and automotive sub-assemblies.
