The Essential

  • Movement realized by a roller carriage and a self-supporting aluminium rail with rack and pinion drive for unlimited strokes
  • Linear unit made to order with customized stroke
  • Technical file with calculation notice supplied on request
  • Self-supporting guide rail hard anodized at 62 HRC over a depth of 15 µm
  • Maintenance-free and lubrication-free linear roller guides
  • Particularly suitable for mounting configurations of two axes in parallel
  • In single-axis configuration, to be reserved for moderate load cases with little overhang
  • Compensation of parallelism defects up to 8 mm for a configuration of two axes mounted in parallel
  • Suitable for use in polluted environments

Main Recommendations

High self-alignment properties thanks to a pivot system with axial play mounted on the roller carriages. Absorption of the angular defect of the profile generated by its bending
