Spindle bearing preload selection is key | Cutting Tool Engineering

1/6/2011· Spindle bearing preload is required for static accuracy. It keeps the rolling elements in contact with the spindle and housing and prevents “play” in the spindle. A gap, or play, would allow the spindle to rattle in the housing, and the position of the spindle centerline could shift. In addition to accuracy, preload is required for stiffness.
