Torque-limiting couplings (TLC)-product-category

Torque-limiting couplings (TLC)

Our torque-limiting couplings are designed to withstand torque spikes such as those caused by the variable-frequency drives used in mills. They feature electronic slip detection and automatic resets to maintain driveline control and protection.


  • Resilience to torque spikes 
  • Engagement at 0 rpm 
  • Electronic control monitoring 
  • Overload detection 
  • Automatic disengagement 


  • Continuously monitors torque to prevent overload of the motor and damage to costly equipment 
  • Resets and restarts instantaneously, ensuring maximum uptime for your operation 
  • Increased torque capacity provides downsizing opportunities, potentially reducing your costs 
  • Simple design extends wear life further and delivers long-term durability 
  • Low-maintenance solution that is easy to install and operate 


  • Ball mills 
  • SAG/AG mills 
  • Variable-frequency drive (VFD) applications
