Product Details
The BL Deep Groove Ball Bearings (Inch) 1615-ZZ are shielded, light duty bearings featuring a 0.4375" bore and a 1.125" outer diameter (OD). Designed for precision, these bearings are domestically interchangeable with traditional (semi-ground) domestic inch series bearings and adhere to ABEC 1 tolerance specifications. The unique design includes grooved raceways on both the inner and outer rings, allowing them to sustain moderate axial loads in both directions in addition to radial loads. The bearing balls are separated by steel cages for enhanced durability. Common interchanges for this model include 21807-77 General, 1615DS Nice, and BR7715 Shatz.
