Description

Synchronous ratcheting – Backlash free – with balls


Advantages
  • Backlash free in both directions of rotation
  • Compact design with high power density
  • Integral ball bearing to support the driven component
  • Very high response accuracy thanks to the ball principle
  • Simple, backlash-free mounting on shaft using integral cone clamping element
  • Calibrated micro adjustment of torque setting possible, even post-installation


Function
  • When the preset limit torque is reached, the SIKUMAT® ratchets through without backlash
  • After removal of the overload, the SIKUMAT® automatically and synchronously re-engages to the start position after 360°
  • An overload can be signalled by a proximity switch, enabling immediate shutdown of the drive or activation of another control function
