2. Characteristics of the Rotex AFN-SB Special Flexible Coupling:
– The Rotex AFN-SB Special Flexible Jaw Couplings are manufactured by KTR/Germany.
– Flexible torsion coupling with brake disc (brake disc coupling / center-release design coupling).
– Dampens vibration and shock.
– Inline, offset, angular compensation.
– Maintenance-free.
– Insulating capability.
– ATEX Coupling compliant, explosion-proof equipment (according to EU Directive 2014/34/EU).
– The KTR Rotex AFN-SB Special shaft coupling ensures the transmission of torque, dampening torsional vibrations, and absorbing shocks caused by uneven machine operation. Flexible ROTEX torsion couplings are used in various types of machinery and plant engineering applications.
– The brake disc and elastic spider of the coupling can be replaced during installation without shifting the drive hub and driven hub. Different stiffness levels of the T-PUR spider allow for adjustment of the damping level and torsional stiffness of the elastic coupling.
– Elastic materials deform under load and high speed. Sufficient expansion space must be provided.
– All sizes of Rotex elastic couplings have a maximum torsional angle of 5 degrees. They can be mounted both horizontally and vertically.
– The material of KTR Rotex AFN-SB Special, T-PUR elastomer, withstands higher temperatures and has significantly longer lifespan compared to conventional polyurethane. T-PUR material is visually marked with orange (92 Sh A), purple (98 Sh A), and light green (64 Sh D).
– Formerly available polyurethane buffers with yellow, red, and natural white colors with green teeth marking are still provided upon request.
