Details:

The '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.

Characteristics

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 Couplings are used in the sector of mechanical engineering, where a torque or a rotary motion has to be transmitted from shaft to shaft in highest accuracy of angle.
