The SKF 6301-2Z is a deep groove ball bearing with double metal shields (2Z), featuring a 12mm inner diameter, 37mm outer diameter, and 12mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it is optimized for dry, dusty environments (e.g., small motors, power tools, agricultural machinery). It handles radial and bidirectional axial loads, offering low friction, excellent dust protection, and long service life.
