The SKF 6220-2Z is a deep groove ball bearing with double metal shields (2Z), featuring a 100mm inner diameter, 180mm outer diameter, and 34mm 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 equipment, grain processing lines). It handles radial and bidirectional axial loads, offering low friction, excellent dust protection, and long service life.
