The SKF 6317-2Z is a deep groove ball bearing with double metal shields (2Z), featuring an 85mm inner diameter, 180mm outer diameter, and 41mm thickness. Constructed from high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for dry, dusty medium-to-heavy load environments (e.g., mining machinery, cement equipment, warehouse conveyors). It handles radial and bidirectional axial loads, offering low friction, dust resistance, and extended service life.
