Properties

  • Design:
    • with clamp collar and screw per ISO 4762
    • components of compact and rigid design with backlash free interface
  • Temperature range: -30° C to +120°C (-22° F to +248° 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 0.01-0.05 mm.
  • 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 SLN:
    • integral bearing for timing belt pulley or sprocket
    • compact, simple construction
    • torque setting is continuously variable
    • frictional clamp connection
    • simple to install
