New Sealed Linear Stage Provides Clean Motion For Dirty Machines

Linear stages in industrial settings often suffer from contamination problems. As manufacturing debris, particulate or liquid contaminants work their way into the stage, they can abrade or gum up the drive mechanism and bearings. Our new SLS Sealed Linear Stage keeps contamination outside the stage housing.

Integrated Polyurethane Seal. The SLS features a proprietary linear lip seal design that integrates seamlessly with the stage’s anodized aluminum housing. Made from a ruggedized polyurethane elastomer, the seal is:

  • Resistant to chemicals, temperature extremes and mechanical wear.
  • Field replaceable in minutes without the disassembling the stage or removing the payload in most cases.

True Positioning. Available with linear motor and ballscrew drives, SLS is a precision positioning device at heart.

  • In linear motor configurations, the SLS can achieve accuracies of ± 4 µm per meter of travel and bi-directional repeatability of ± 2 µm.
  • In ballscrew configurations, the SLS can achieve accuracies of ± 10 µm per meter of travel and bi-directional repeatability of ± 5 µm.

Compact, Fast and Strong. Self-contained in a housing that’s 185 mm wide and just 80 mm tall, SLS packs a lot of capabilities into a small package.

  • Available with standard travel lengths from 100 to 1,000 mm and custom lengths to 2,000 mm.
  • Speeds to 4 m/sec for linear motor drives and 0.4 m/sec for ballscrew drives.
  • Continuous linear force to 300 N for linear motor drives and 1,540 N for ballscrew drives.

Demanding Applications. With its anodized housing and urethane seals, SLS targets applications with harsh operating environments including:

  • Laser machining.
  • Welding.
  • Semiconductor.
  • Machining.
