Part Number: WB730
The saddle nut threads onto the cross-slide leadscrew and converts rotary motion from the feed box into linear travel of the tool saddle. As it wears, backlash develops — the saddle drifts and positioning accuracy degrades. Saddle nut replacement restores precision without a full saddle rebuild.

Often ordered with WB734 (saddle locknut). Check the locknut condition when replacing the saddle nut.
Technical Note: Always confirm the exact saddle nut variant with the machine serial number. WB730 and WB731 are the most common, but WB921 and WB922 exist for certain configurations.
