Fluid Couplings


Fluid hydraulic soft-start couplings available in various sizes and types up to 700kW (950HP) capacity.

  • New “drop-in replacement” with sleeve, end-plate & adaptors.
  • Flexible couplings and pulley designs.
  • Soft-start allowing the motor to accelerate unloaded.
  • Reduces motor size and drive package cost.
  • Delay fill version – extending acceleration time and further reducing start-up torque.
  • Reduces peak current demand on the motor.
  • Reduces belt stretch on start-up and provides motor overload protection (mech. Fuse)

Renold Synergy represents the biggest single innovation in power transmission technology since the bush and roller chain were invented. Its wear resistance and performance capabilities are without equal.
