Properties

  • Design:
    • pure keyway connection
    • torque limiting element is backlash free
  • Temperature 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 and shaft 0.01 – 0.05 mm.
  • Material: High-strength, hardened steel
  • Properties of Torque Limiter model SKP:
    • absolutely backlash-free and torsionally rigid
    • compact, simple design
    • disengagement detection achieved through high indexing ring movement
    • low residual friction following disengagement
    • low moment of interia
    • self-adjusting
    • disengagement within 1 - 3 msecs
