The SKF 6220 is an open deep groove ball bearing (unsealed), featuring a 100mm inner diameter, 180mm outer diameter, and 34mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it suits medium-speed, medium-load applications (e.g., large industrial motors, mining machinery, heavy-duty gearboxes). It handles radial and bidirectional axial loads, offering high rigidity, low friction, and easy maintenance.
