Safety couplings

The Heavy Duty safety couplings from R+W Couplings ensure a quick disconnection of the drive train at precisely preset torque limits. The standard version of this coupling is available in the range of 200 to 250,000 Nm. Customized versions can be created for torques exceeding 18,000,000 Nm. The application areas of these Heavy Duty couplings are primarily where torque overload occurs.
