The SKF 6217-2Z is a deep groove ball bearing with double metal shields (2Z), featuring an 85mm inner diameter, 150mm outer diameter, and 28mm 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.
