Product Details
BL deep groove ball bearings (inch) 1633-ZZ are shielded, light duty bearings featuring a 0.625" bore and a 1.75" 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 feature grooved raceways on both the inner and outer rings, which allow them to sustain moderate axial loads in both directions alongside radial loads. The bearings are equipped with steel cages that separate the balls for optimal performance. Common interchanges include 22810-77 General, 1633DS Nice, and BR7733 Shatz.
