Roller screws

Roller screws
Benefits:
  • Heavy load capacity and high axial rigidity with additional preloaded versions
  • exceptional performance in applications with frequent direction changes and high linear speed
  • high positioning accuracy with excellent repeatability and reliability
  • customer-specific feasibility study
Features:
  • Heavy load capacity, pitches from 1 to 50 mm and long service life
  • 3 Nut with or without ball recirculation
  • High speed depending on diameter of screw, N.d0 max. up to 160.000
  • with axial play, with slip prevention or with preload

A variety of industries use roller screws from Ewellix for their drive mechanisms. Our roller screws are a shining example of the departure from conventional linear solutions and the pinnacle of a new generation of innovative and powerful electromechanical drive systems.
Ewellix is a pioneer in this field with the market's largest range of high performance roller screws.
Thanks to their high precision and rigidity, roller screws are the ideal choice for heavy loads, long duty cycles, high speeds, high linear speeds, high accelerations (especially planetary roller screws) and harsh operating conditions.
Ewellix offers 3 different types of roller screws for different applications:
Planetary roller screws, recirculating roller screws and inverted roller screws.
