The SKF 6006 is an open deep groove ball bearing (unsealed), featuring a 30mm inner diameter, 55mm outer diameter, and 13mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it suits medium-speed, medium-load applications in clean environments (e.g., machine tool spindles, automotive gearboxes). It handles radial and bidirectional axial loads and requires regular lubrication.
