The Essential

  • Compact size
  • Corrosion resistant surface
  • Smooth motion
  • Hardened and honed raceways surface
  • Sliders with four rollers arranged in pairs
  • Not sensitive to dirt due to the large rollers
  • Low maintenance
  • Quieter than recirculating ball systems
  • MiniRoller Rail profile rails can be drop-in replace linear guides from another manufacturers while maintaining the same critical dimensions.

Performance characteristics:

  • Max. slider operating speed on the rail: 3 m/s (118 in/s) (depending on application)
  • Max. acceleration: 5 m/s² (196 in/s²) (depending on application)
  • Available rail lengths up to 1950 mm (78.74 in)
  • Temperature range: -20 °C to +80 °C (-4 °F to +176 °F)
  • Rail material: standard C43
  • Rail raceways are induction hardened and honed
  • Rails and slider bodies are standard electrolytic zinc-plated and passivated; increased anticorrosive protection on request (see pg. MRR-9 Anticorrosive protection)
  • Slider body material: steel DIN 9SMnPb28, AISI 304 for the stainless steel version
  • Rollers material: standard steel 100Cr6, AISI 440C for the stainless steel, zinc nickel and nickel plated versions
  • Rollers are lubricated for life
  • Roller seal/shield: standard 2Z (steel cover disk), 2RS (splash-proof)
  • Maximum parallelism deviation: 0.03 mm
