Highly flexible D couplings are especially well-suited for engine test rigs for testing 1‑ to 3-cylinder internal combustion engines. D couplings feature a high torsional flexibility and high torque capacity. Development test rigs, continuous-running test rigs, and end-of-line test rigs operate safely and reliably with this coupling at speeds of up to 10 000 rpm.

D couplings shift a system's critical resonance frequencies below the operational speed range. In addition, the couplings dampen undesirable alternating torques. This increases the service life of all the test rig drive components. Your test rig operates with a high level of availability.

The D coupling's modular design enables very flexible integration into a wide variety of engine test rigs. We adapt the length of the coupling, connections, and torsional rigidity to your test rig. D couplings feature high torsional flexibility. This makes it possible to reproduce test cycles more precisely in supercritical operation and to achieve particularly precise test results.
A built-in spherical joint ensures balance between the engine and the power take-off. This test rig coupling is suited for engine speeds of up to 10 000 rpm. High-speed engines can be tested up to their maximum speed in most cases.
The coupling's modular design makes it easy to integrate into a wide variety of engine test rigs. The connections can be adapted to almost all types of engines and dynos. This saves on adaptation expenses and allows you to build a better design with a shorter lever arm.
