Complete-Set Selection
We recommend quoting support units and lock nuts together with your ball screw: include the screw part number (or shaft diameter) in your inquiry and Nahshon will match fixed- and support-side units and lock nuts per the official NSK shaft-end tables (E3162 B27–B30) — one quotation, one complete delivery.
