Balls torque limiters (backlash free)

A ball safety coupling with high technology and precision. Provides backlash free transmission of motion with high sensitivity of reaction and an immediate release without peak load prior to release. The device can be adjusted by changing the pressure of the springs in the negative.

• To protect the product against faulty positioning on the rotating table
  
• To protect the indexing against overloading along the transmission
  
• To protect the operating units of machine tools against impacts
• To protect slides or servomotors against impact or limit stops
