Backlash-free Metal Bellows Coupling Series PKB with locking ring Series PKB with locking ring Metal bellows made of stainless steel, hubs made of aluminum Backlash-free and torsional stiffness High-tensile pluggable hub High power performance Wear- and maintenance-free Axial pluggable Axial mountable from in- and outside Technical Data T KN = Nominal torque M A = Tightening torque of retaining screws C y dyn = Dynamic torsional stiffness Cr = Radial spring stiffness Ca = Axial spring stiffness n max = Max. rotational speed V = Preload distance △Ka = Max. approved misalignment axial △Kw = Max. approved misalignment angular △Kr = Max. approved misalignment radial J = Moment of inertia

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. Backlash-free transmission of torque High torsional stiffness, precision of transmission of rotational angle Different torsional stiffness Compact design, low moment of inertia Metal bellows made of stainless steel Simple and safe assembly Compensation of radial, axial and angular misalignment Free of wear, maintenance-free, no downtimes Not sensitive to temperatures between -30°C and +100°C Nominal torques between 0,1 – 5000 Nm Advantages 100% inspection and traceability through individual marking Higher torques at same dimensions Compact design Extended bore ranges Customer-specific solutions Higher safety in application, e.g. no wrong screw tightening torques Backlash-free Metal Bellows...

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.

Examples of applications include pressure switches or thermostats: Deep-drawing techniques to manufacture seamless tubing up to 50mm ID and 450mm length - in wall-thicknesses as low as 0,064mm. Based on this, our smalles precision bellows start with only 6X4,2mm. Mainly requested with individual bottom shape, they are performing as reliable force transmitters. Besides bronze and brass, stainless steel and other alloys are available.

Stainless steel bellows, formed from seam-welded thin wall tubing Stainless steel bellows, formed from deep-drawn seamless tubing Bronze and Brass bellows for measuring and controlling applications Hydroformed bellows from exotic alloys as Beryllium copper or Monel400 Customized designs and end forms, also off-the-shelf standard solutions Special coatings on demand

Requirements to stainless steel bellows used in energy distribution (vacuum circuit breaker) systems: - Shiny, immaculate surface - Hermetic sealing for ultra-high vacuum - Exact spring rate characteristics - Long lifecycle - Consistent weld-line and possibility to weld/assembly in vacuum Sophisticated washing technologies and seamless designs allows Mera Bellows to meet these requirements for competitive pricing. Test us.

Due to change in weather (wind, sun, snow...), pipe systems of solar thermal systems are subject to thermal expansion, to vibration, to make in short; various movements that have to be compensated in order to keep the system stable. Mera Bellows manufactures stainless steel expansion joints, formed from thin-walled seam-welded tubes, that are widely used for this scope of application.
