SLS Sealed Linear Stage

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. Loss of precision and shortened lifecycle follow. Our Light and Medium SLS Sealed Linear Stages keep contamination in its proper place—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 disassembling the stage—or even removing the payload in most cases.

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

  • In linear motor configurations, the SLS can achieve accuracies of ± 2.0 μm and bi-directional repeatability of ± 0.5 μm.
  • In ballscrew configurations, the SLS can achieve accuracies of ± 4.0 μm and bi-directional repeatability of ± 1.0 μm.

Compact, Fast and Strong. SLS comes in two sizes—Light and Medium. Both models pack a lot of capabilities into a small package measuring just 80-mm high by 120-mm wide for the Light model and 180-mm wide for the Medium:

  • 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 the linear motor drives and 1,400 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.
