Metal Bellows Couplings
Metal bellows couplings made by GERWAH are the perfect choice in many areas where torsionally rigid and backlash-free shaft connections are required. Our high-quality products can compensate angular, axial and radial misalignments and transmit the rotational angle with highest precision. Compact shape and low moments of inertia can be taken for granted in our self-aligning couplings.
Servo-Insert Couplings
Backlash-free, vibration-damping, with a plug-in mounting: GERWAH Servo-Insert Couplings are used in driving technology when precise, low-vibration power transmission is required. The flexible elements compensate angular, axial and radial misalignments of the shafts. Depending on the chosen type, the couplings are made for torques of up to 650 Nm.
Line Shafts
GERWAH backlash-free Line Shafts are the perfect choice when large centre distances have to be covered. The elements are available with metal bellows or elastomeric spiders. Torque and rotating movements are transmitted with highest angular accuracy while misalignments are compensated easily. Installation lengths of up to six metres are possible.
Safety Couplings
Farewell to breakdowns, overload and collisions: GERWAH Safety Couplings protect engines, servos and connections from damage due to operation errors or malfunction. In case of overload, the high-speed cut-out function of the coupling disconnects the backlash-free connection of driver and driven component within milliseconds.
GERWAH® Torsionally Rigid Disc Couplings
Our flexible Torsionally Rigid Disc Couplings can compensate for angular, axial, and radial misalignments while transmitting torque backlash-free between driver and driven components. They operate without wear or maintenance, never need lubrication, and, due to their all-metal construction, are insensitive even to very high temperatures. Rigid Disc couplings are pre-engineered to be connected to the shaft with variable RINGFEDER keyless locking devices.
