Robotics and Automation Safety brakes, servo couplings and torque limiters

Brake technology that inspires

In the field of robotics and automation, mayr® power transmission has developed high-performance safety brakes which are perfectly tailored to the demands of robots. They permanently ensure the reliable protection of people and materials, and prove themselves every day in numerous robotics applications worldwide. Irrespective of whether in industrial robots which collaborate with people in production lines, in medical engineering or in fairground attractions in theme parks – safety does not allow for compromises.

Besides brakes, the clutches/couplings by mayr® power transmission also render reliable services in robotics and automated solutions. A wide spectrum of backlash-free, high-performance servo couplings ensures a reliable connection between shafts. These proven torque limiters stand for permanently reliable overload protection – for maximum operating safety and productivity.

ROBA®-pinionstop safety brakes are dimensioned and designed individually. Contact us! We are happy to help you find the optimum solution for your application. (The basis for the ROBA®-pinionstop is mainly the construction series ROBA-stop®-M (catalogue K.891.V_ _._ _). Depending on the installation situation, the toothed rack profile and the technical requirements, we create the appropriate brake for you with an integrated pinion.)

ROBA®-DS (servo)
