The SKF 6211-2Z is a deep groove ball bearing with double metal shields (2Z), featuring a 55mm inner diameter, 100mm outer diameter, and 21mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for dry, dusty environments (e.g., mining machinery, grain processing equipment, automation lines). It handles radial and bidirectional axial loads, offering low friction, excellent dust protection, and long service life.
