Product Details
The BL deep groove ball bearings (inch) 1603-ZZ are shielded, light duty bearings featuring a 0.3125" bore and a 0.875" outer diameter (OD). These precision ground bearings are designed to be domestically interchangeable with traditional (semi-ground) domestic inch series bearings and meet ABEC 1 tolerance standards. They incorporate grooved raceways on both the inner and outer rings, allowing them to handle moderate axial loads in both directions, in addition to radial loads. The balls within the bearings are separated by steel cages, ensuring durability and performance. Common interchanges include 21405-77 General, 1603DS Nice, and BR7703 Shatz.
