Description

Product type
  • Ratcheting torque limiter with screw faces (SIKUMAT® SC)


Advantages
  • Excellent robustness through surface contact during the disengaging process for maximum service life
  • Fully enclosed housing with integral bearing for maintenance-free operation
  • Torque setting adjusted by number of active springs, not by changing spring preload


Function
  • When the preset limit torque is reached the SIKUMAT® ratchets to protect the drive
  • After removal of the overload the SIKUMAT® automatically re-engages
  • An optional special proximity switch for the ratcheting SIKUMAT® with screw faces can signal the overload to stop the drive or activate other control functions
