The SKF 6300 is an open deep groove ball bearing (unsealed), featuring a 10mm inner diameter, 35mm outer diameter, and 11mm thickness. Made of high-carbon chromium steel (GCr15) with a pressed steel cage, it suits medium-speed, light-load applications (e.g., micro motors, instrumentation, small transmission devices). It handles radial and bidirectional axial loads, offering high rigidity, low friction, and easy maintenance.
