The ROBA contitorque permanent magnet hysteresis clutch and brake range from Mayr Transmissions has been expanded with the introduction of a new size 5 unit, providing a slip torque range of 0.1 to 12Nm. ROBA contitorque offers wear free and reliable torque limitation in continuous slip applications. Unlike friction type devices, torque is transmitted without contact via magnetic forces which greatly extends service life and ensures extremely accurate and repeatable slip torque values. This maintenance free product is suitable for load holding, tensioning or torque limiting applications and its compact design, low weight and mass moment of inertia allows easy integration into a wide range of applications.
