  • Ball Sorting Preload - Single nut preloaded by ball sorting with 4-point ball contact between nut and screw
  • Compact Design - Requires shorter screw length than double nut for the same stroke
  • Production Tolerance Considerations - Due to production tolerances, single nuts are mainly used for shorter ball screws
  • Load Peak Protection - No inadmissible complete ball disengagement even during load peaks
  • Economical Manufacturing - Single nut ball screws can be manufactured more economically than double nuts
