SAB Series

Self-supported axis with polyamide-coated rollers. Linear speeds up to 15 m/s.
Available Sizes
60 120 180 250

SAB Series actuators are self-supporting extruded aluminum actuators driven by a polyurethane belt system. Due to their deep hard anodized surface treatment and their plastic compound coated rollers, SAB series can achieve exceptionally high performances and load capacity with no maintenance or lubrication required, even in dirty environments.

Choose your configuration


  • Movement realized by a roller carriage and self-supporting aluminum rail with toothed belt drive
  • Customized stroke. Linear unit made to order
  • Technical file with calculation notice supplied on request
  • Linear unit without lubrication and “zero maintenance”.
  • Self-supporting beam rail hard anodized at 62 HRC over a depth of 15 µm
  • Best suited for “single-axis” type configurations under moderate load with little overhang
  • Extremely quiet, lightweight, easy to assemble and modular

Main Recommendations

SAB’s rollers and belt drive offer high dynamics, near silent, lifetime lubrication-free operation.
