Need reliable bearings for a repair or project? This pack of four 6903-2RS deep groove ball bearings is a great value. Each bearing has a 17mm inner diameter, 30mm outer diameter, and is 7mm thick – a common size used in small electric motors, gearboxes, pumps, skateboards, and all sorts of rotating machinery. They're double-sealed (2RS) with rubber seals on both sides to keep grease in and dirt out, making them good for applications where they might get dusty or damp. They're made from durable carbon steel with a steel cage and have a P0 (ABEC-1) accuracy rating, which is perfect for most general industrial and DIY uses. Buying a 4-pack is smart because you'll often need more than one, or you'll have spares for future projects. Always double-check your dimensions against the old bearing, but if you need 17x30x7mm sealed bearings, this set will get your equipment spinning smoothly again.
