Rollers torque limiters

Rollers torque limiter

Safety coupling with the transmission of motion through rollers that allow complete disengagement when the calibrated torque is reached permitting a quick stop of the transmission due to micro-EM1. Suitable for transmitting high torque with high reliability and compact size.

  • Protects the gearbox from jamming due to foreign matters
  • Protects packages from squashing and deforming
  • Protects the product handling elements from accumulations
  • Maintains the timing between driver and driven after an overload

On request

  • Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair)
  • Possibility to use helical springs for low intervention torques
  • Connections with bore and keyway, locking assembly possible
  • Version with personalized re-engagement in phase 36°, 45°, 60°, 90°, 120°,… 


Short info

  • Precise torque setting by adjusting the radially balanced locking nut
  • Innovative calibration system for an immediate calibration of the device
  • Equidistant re-engagement in phase or at 360°
  • Available with electromechanical switch / proximity for the transmission disconnection
  • Immediate intervention for an improved reaction compared to electronic systems
  • Maintenance-free for long lasting high reliability
  • Suitable for oily and wet environment

Main applications

  • Packaging and wrapping machines
  • Labelling machines
  • Bottling machines
  • Conveyors
