Product Details
The BL deep groove ball bearings (inch) 1638-ZZ are shielded, light duty bearings featuring a 0.75" bore and a 2" outer diameter (OD). These precision ground bearings are designed to be domestically interchangeable with traditional (semi-ground) domestic inch series bearings. They incorporate ABEC 1 tolerance and have grooved raceways on both the inner and outer rings, allowing them to sustain moderate axial loads in both directions as well as radial loads. The balls are separated by steel cages for enhanced performance. Common interchanges for this product include 23212-77 General, 1638DS Nice, and BR7738 Shatz.
