- Ball Bearing: Ball bearings, including deep groove ball bearings, utilize spherical balls as rolling elements that move between inner and outer raceways. They are primarily designed to support radial loads, with some designs capable of handling limited axial loads. Ball bearings are commonly used in applications where smooth and efficient rotation is required, such as in electric motors, pumps, and gearboxes.
Features of the 6903 ZZ Bearing One of the most critical factors in cross referencing tapered bearings is the bore size. The bore size must be accurately measured to ensure that the bearing fits snugly onto the shaft. If the bore size is too large or too small, it can cause excessive wear or damage to the bearing If the bore size is too large or too small, it can cause excessive wear or damage to the bearing
