# Staged Locknut Tightening That Avoids Brinell Marks

One hard pull can brinell a race or overshoot target preload. Tighten in stages, rotate the spindle between pulls, and re-check drag or axial response. Mark final nut position; treat torque as a secondary cue behind geometry.

Follow staged locknut preload steps. TFL Bearing shows verification checks beside the calculation outline.
