The SKF 6302-2Z is a deep groove ball bearing with double metal shields (2Z), featuring a 15mm inner diameter, 42mm outer diameter, and 13mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for dry, dusty environments (e.g., warehouse machinery, office equipment, small agricultural machines). It handles radial and bidirectional axial loads, offering low friction, excellent dust protection, and long service life.
