Rollers torque limiter

Up to 12 kNm of torque and 120 mm bore diameters.

Home › Products › Torque limiters › Rollers torque limiter

A safety coupling featuring roller-based motion transmission. It allows for complete disengagement when the set torque is reached, permitting a quick transmission stop via the EM1 microswitch. Suitable for transmitting high torque with high reliability in a compact size.

  • Precise torque setting via adjustment of the radially balanced locking nut;
  • Innovative nominal torque regulation based on the “H” dimension allows for immediate calibration;
  • Equidistant (multi-position) or 360° synchronous re-engagement;
  • Compatible with electromechanical switches or proximity sensors for transmission disconnection;
  • Immediate intervention offering superior reaction time compared to electronic systems;
  • Maintenance-free for long-lasting high reliability;
  • Suitable for oily and wet environments.
  • Supplied complete with machined and assembled transmission elements (plate wheel, pulley, gear pair);
  • Helical springs available for low torque settings;
  • Connection options include bore and keyway, or locking assemblies;
  • Customized phase re-engagement angles available (36°, 45°, 60°, 90°, 120°, etc.).
  • Packaging and wrapping machines;
  • Labeling machines;
  • Bottling machines;
  • Conveyors.
  • Protects the gearbox from jamming caused by foreign objects;
  • Prevents package crushing and deformation;
  • Protects product handling elements from accumulation/jams;
  • Maintains synchronization between driving and driven components after an overload (360° version).
