Precision rolled ball screws DIN standard SND / BND / PND

Precision rolled ball screws DIN standard SND / BND / PND
This range of ball screws offers interchange ability, excellent value and a competitive alternative to ground ball screws. The SKF range of ball screws with nut design according to DIN standard 69051, based on precision rolling technology, offer compact, highly efficient driving solutions.
With precision grinding of the nut outside diameter, flange face and nut thread, this design fits most positioning applications. If further positioning accuracy is required, SKF offers this range with backlash elimination or with preload.

Features and benefits

  • Optional reduced axial play from 0,05 to 0,08 mm, depending on size (SND version)
  • Standard preload 7% to 8,5% of ball screw Ca value, depending on ball screw size (PND version)
  • Standard composite recirculation inserts
  • Optional steel recirculation inserts
  • Standard lead precision G5, G7 and G9
  • Nut ground outside diameter / flange face
  • Precision ground nut thread
  • Lubrication hole for grease nipple or for SKF SYSTEM 24 automatic lubrication kit
  • Optional surface coating on shaft and nut
  • Optional safety nuts
  • Optional wipers
  • Optional support bearings
  • Compact nut / integral flange for easy assembly
