Product Details
The BL deep groove ball bearings (inch) 1620-ZZ are shielded, light duty bearings featuring a 0.4375" bore and a 1.375" outer diameter (OD). Designed with precision ground attributes, these bearings are domestically interchangeable with traditional (semi-ground) domestic inch series bearings and incorporate ABEC 1 tolerance standards. They feature grooved raceways on both the inner and outer rings, allowing them to support moderate axial loads in both directions in addition to radial loads. The balls are separated by steel cages, ensuring durability and performance. Common interchanges for these bearings include 22207-77 General, 1620DS Nice, and BR7720 Shatz.
