Rollers torque limiters

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
