3. Characteristics of Rotex CFN Flexible Coupling:
– Rotex CFN Flexible Jaw Couplings are manufactured by KTR/Germany.
– Can be mounted without displacing the drive components.
– Especially short installation length.
– Flange material made of GGG40 (nodular cast iron).
– Customizable flange mounting upon request.
– Flange and drive hub are pre-assembled.
– Effective vibration damping.
– Axial, radial, angular misalignment compensation.
– ATEX compliant (according to EU Directive 2014/34/EU).
– No maintenance required.
– Function of Rotex Shaft Couplings: Rotex CFN reduces torsional vibrations and absorbs shocks, making it particularly suitable for heavy industrial applications.
– Damping Ring (spider): Reduces torsional vibrations; the T-PUR damping ring is high-temperature resistant and comes in various hardness levels.
– Double Flange Design: Allows for easy assembly and disassembly without moving the equipment.
– All sizes of Rotex flexible couplings have a maximum torsion angle of 5°. They can be mounted both horizontally and vertically.
– The elastic damping materials deform under high loads and speeds, requiring adequate expansion space.
– Material of KTR Rotex CFN Coupling: T-PUR material withstands higher temperatures and has significantly longer lifespan compared to conventional polyurethane. T-Pur material comes in visually distinctive colors: orange (92 Sh A), purple (98 Sh A), and light green (64 Sh D).
– Previously used polyurethane damping rings with yellow, red, and natural white colors with green tooth markings are still available upon request.
