    Properties

    • Design:
      • with clamping hub and 1 radial screw ISO 4762
      • absolutely backlash free through frictional clamping connection
    • Tempertaure range: -30° C to +120° C (-22° F to +248° F)
    • Service life: Maintenance free when operated within the technical specifications.
    • Tolerance: Tolerance between hub an shaft 0.01 - 0.05 mm.
    • Material:
      • torque limiting portion: high-strength, hardened steel
      • clamping hub: up to series 500, aluminium
      • from series 800, steel
    • Properties of Torque Limiter model SKN:
      • absolutely backlash-free and torsionally rigid
      • compact, simple design
      • disengagement detection is achieved through indexing ring movement
      • low residual friction following disengagement
      • low moment of interia
      • precise overload protection
      • disengagement within msecs
