Ringfeder Torsional Highflex Couplings TNR 2428.2
TNR 2428.2 shaft coupling delivers high torque and vibration control.
Ringfeder TNR 2428.2 is a double-row torsional highflex coupling designed for shaft-to-shaft connections. Its service-friendly design allows elastic buffers to be replaced without axial movement or disassembly of the connected machinery, helping minimise maintenance time and downtime.
Developed primarily for internal combustion engine applications, the TNR 2428.2 effectively manages torsional vibrations caused by fluctuating loads and wide operating speed ranges. The double-row elastomer design provides increased torque capacity and enhanced torsional flexibility, allowing the coupling stiffness to be precisely tuned to the requirements of each drivetrain.
The compact plug-in construction enables installation in restricted spaces, while the modular design supports a wide range of industrial applications. The coupling can also be configured as a puncture-proof solution through simple modifications, providing additional operational security where required.
