description
- Semiground 3000 series bearings are specially designed to provide a line of economical bearings for lighter loads than the 1600 series and speeds to approximately 2,500 rpm. The 3000 bearings are dimensionally the same as the 1600 series bearings, except for the precision of the inner ring (as machined tolerances). Careful heat treatment provides a uniform and exact degree of hardness for maximum life. The 3000 series bearings are precision-ground to the same close tolerances on the O.D. as the 1600 series with exceptional care given to the ball grooves. A ball retainer, or separator, is employed to increase the range of allowable speeds by reducing ball contact friction. The 3000 series radial bearing is available open, single, or doubled shielded, or single or double sealed. The double-shielded and double-sealed versions are grease packed as standard. Open and single-closure bearings can be furnished with or without grease as desired.
