Recirculating roller screws

Benefits:
  • High load capacity and rigidity, further increased by preloaded options
  • Extremely accurate positioning with excellent repeatability
  • Limited torque applied due to short wheelbase and enhanced efficiency
  • Improved robustness and reliability to ensure long service life
Features:
  • Very fine lead down to 1,0 mm, while providing a high load carrying capacity and high axial stiffness
  • Heavy load capacity and long service life
  • Low back driving ability
  • No miniature parts

Roller screws with roller recirculation offer an ultra-precise drive solution thanks to a perfect combination of high load capacity, the smallest possible pitch for fine resolution, high positioning accuracy and axial rigidity.
The small pitches or pitch angles of the spindle thread reduce both backward motion and rolling friction.
