Tips for adjusting spindle bearing preload on a lathe

Dec 21, 2021· The bearing preload may change or it might stay constant with temperature. It is sometimes recommended to tap the spindle after adjusting the bearing retaining nut to insure that the bearing pair slides along the spindle. It is a stick-slip motion. It is possible that a small adjustment in the retaining nut will not cause the bearing to move
