Planetary roller screws

  • Longer service life due to increased robustness
  • High-reliability, low noise, high rotational speed (N.d0 max = 160000)
  • Exceptional behaviour in situations with frequent changes of direction and high linear speed, up to 1.8m/s
  • Customised designs possible
  • Heavy load capacity with up to a 50 mm long lead
  • Planetary concept without recirculation and rollers, synchronised by cogs
  • Adaptable tooling for non-standard, left handed thread or customised designs
  • Axial play or preloaded execution on request

Ewellix has the largest selection of planetary roller screws on the market to meet any requirements. The planetary roller screw drives without roller recirculation ensuring ultimate drive performance. They are extremely robust and load-bearing, offer maximum performance in terms of speed and acceleration and are extremely durable and reliable. Thanks to state-of-the-art machining technology, Ewellix can offer planetary roller screws in a wide range of diameters and gradients.
Through the use of the latest machining equipment, Ewellix can offer planetary roller screws from very small to very large diameters, with a wide variety of lead.
