3. Characteristics of KTR Rotex DFN Flexible Couplings:
– Rotex DFN Flexible Jaw Couplings are manufactured by KTR/Germany.
– The coupling is a vibration-resistant, torsionally flexible flange coupling (flange coupling) with flange connections on both sides.
– Double-flange type for heavy-duty applications.
– Designed for driving and driven machine screw connections.
– Can be mounted axially without replacing other components.
– The spider can be replaced quickly.
– Flange material: part 3b made of GGG40 (nodular cast iron).
– Compact outer dimensions.
– Flange and drive center are available from stock.
– Coaxial, axial, angular compensation.
– Complies with ATEX regulations (according to EU Directive 2014/34/EU).
– No regular maintenance required.
– The jaw couplings ensure transmission of torque, vibration resistance, and absorption of vibrations caused by uneven machine operation.
– Rotex DFN coupling is a compactly designed flexible coupling. Despite the low weight and inertia of the flexible couplings, they can transmit high torsional moments. The compact shaft couplings are characterized by long service life and the sound operational characteristics generated by the entire machining process.
– All sizes of KTR Rotex DFN couplings have a maximum torsional angle of 5°. They can be mounted horizontally and vertically.

4. Applications of KTR Rotex DFN Flexible Couplings:
The combination of the KTR Rotex DFN flexible couplings and this brake disc is used wherever braking or maintenance braking is required, such as on conveyor belts, power generators, turbine drive systems, industrial fans, shafts, and winches. Drive systems related to safety are better combined with Rotex centers made of steel/GJS. Applications with moderate demands can be combined with GJL centers.
