GERWAH's 'EKN miniatur' is a backlash-free metal bellows coupling which boasts a very compact shape. The miniature coupling is connected to the shaft by means of radial set screws instead of a clamping hub. The element can be used in many different areas and displays all its advantages when misalignments between driver and driven components have to be compensated.
Thanks to its compact design, GERWAH's metal bellows coupling model 'DKN' is perfectly qualified for backlash-free connections in confined spaces. It is mounted on driver and driven components by means of clamping hubs. High-quality build and material guarantee for maximum durability.
The DKN/S series is characterized by its compact shapes and a low moment of inertia. The shaft connection can be realized by means of a clamping hub on one side and an expanding clamp on the other. In addition, this pioneering element produced by GERWAH boasts unequalled product quality.
GERWAH's 'PKN' unites the tried and tested technical advantages of a metal bellows coupling and a plug-in connection. These elements do not need any axial initial load due to tightening and thus allow for easy mounting and disassembly. The PKN series is the perfect choice when power has to be transmitted from shaft to shaft with the greatest possible angular accuracy.
The metal bellows couplings from the 'AKN' series boast GERWAH's trusted quality and increased torsional stiffness. The reduced shafts in the element guarantee for high stiffness while at the same time compensating angular, axial and radial misalignments. The shaft connection is established by means of clamping hubs on both sides.
GERWAH's production series 'AKD' offers the traditional metal bellows coupling which can be used for a wide range of applications. Its core characteristics are the backlash-free transmission of torque, high torsional stiffness, and excellent compensation of angular, axial and radial misalignments. Operational safety and easy assembly are two more factors speaking in favour of AKD.
Metal bellows couplings from the 'AK' series have been designed especially for the backlash-free transmission of high torques of up to 5,000 Nm. The elements are mounted on driver and driven components with tapered clamping bushings. Depending on the required size, the coupling will be produced with hubs made of aluminium or stainless steel. In addition, AK guarantees for perfect concentric running.
CKN' is GERWAH's production series which grants customers a maximum of application liberties. The flange mounting offers manifold possibilities to establish a connection with the element or add hubs, flanges and fittings. Depending on the chosen model, CKN has been designed for very high torques of up to 5,000 Nm.
The characteristics of the bellows coupling can be modified by varying the number and spacing of convolutions. This type of coupling has high torsional stiffness and may be used in any drive system where high levels of torsional integrity are essential. Typical applications include encoder drives and closed loop servo systems.
This completely stress-free electrodeposited nickel bellows has a precisely controlled thickness which gives it an excellent combination of radial and angular flexibility and high torsional stiffness. It is often used in instrumentation, medical equipment, sensitive high precision drives and similar high precision positioning systems because of its exceptional integrity of angular position between input and output shafts.
