  • Movement made by a roller carriage running on two hardened steel prismatic rails and a rack and pinion system with hardened and ground helical teeth
  • Linear unit made to order with customized stroke
  • Technical file with calculation notice supplied on request
  • Suitable for both mounting configurations of two axes in parallel or single-axis
  • In single-axis configuration, to be reserved for medium load cases with little overhang
  • Very good repeatability even over very long lengths
  • Integrated cable carrier chain and duct available. Possibility of several independent carriage
  • Pivot with axial play present on the carriage for compensating parallelism defects and for absorbing the angular defect generated by the bending of the profile
  • Numerous mechanical options available: detector support, automatic lubrication, vertical blocker, anti-fall safety device…
  • Connection interfaces available for creating “Pick & Place” multi-axis

Main Recommendations

Rigid self-supporting axis. Aluminium profile with very high inertia moment value allowing spacing of pillar up to 6 m

Easy assembly and positioning of pillar supporting profile. “Free” fixing in aluminium profile groove
