The SKF 6312-2Z is a deep groove ball bearing with double metal shields (2Z), featuring a 60mm inner diameter, 130mm outer diameter, and 31mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for dry, dusty environments (e.g., mining machinery, cement production lines, warehouse equipment). It handles radial and bidirectional axial loads, offering low friction, excellent dust protection, and long service life.
