Properties

  • Design:
    • clamping hub with one ISO 4762 screw per hub.

    • components of compact and rigid design with backlash free interface.

    • misalignment compensation via elastomer insert.
  • Temperature range: -30° C to +100°C (-22° F to 212° F)
  • Service life: These couplings are maintenance free and stable over their entire service life if technical limits are not exceeded.
  • Tolerance: Overall clearance between shaft and hub 0.01-0.05mm.
  • Function system:
    • W = single position engagement (standard)
    • D = multi position engagement every 60° (30, 45, 90° optional)
  • Design/Features:
    • extremely lightweight construction
    • up to 60 % weight reduction in comparison to the standard series
    • torque rating increased by 50 %
    • good dynamic characteristics
    • spring tensioned ball-detent principle with absolutely zero backlash
    • corrosion resistant
    • very simple torque setting
  • Properties of Torque Limiter model SLE:
    • easy to install
    • vibration damping
    • misalignment compensation
    • torque setting is continuously variable
