Product Information
Precision-ground 1600 series bearings are specially designed to provide a line of low-cost yet high quality bearings for adaptations. They are made in easy-to-use inch dimensions and are recommended for medium loads and for maximum speeds in the range of 5,000 rpm. The 1600 series bearings are precision ground on all surfaces with exceptional care given to the ball grooves. Careful heat treatment provides a uniform and exact degree of hardness for maximum life. A ball retainer or separator is used to increase the range of allowable speeds by reducing ball-to-ball contact friction. The 1600 series radial bearings are available open, single, or doubled shielded, or single or double sealed. Double-sealed and double-shielded bearings are supplied grease packed as standard. Open and single-closure bearings can be supplied greased on request.
