Couplings, Collars and Universal Joints

Ever seen a flexible coupling fail in a way that tells a story?

Take this example: a coupling element where the central hole has deformed into a square shape. At first glance, it looks unusual, almost like a manufacturing defect. But in reality, it’s a clear signature of overload in action.

Here’s what’s happening beneath the surface:

This range of torsional couplings solve torsional vibration problems typical of those found in diesel engine applications. The torsional coupling dampens torsional vibrations and tunes the system to have critical speeds outside the operating range.
jbj Techniques Ltd can analyse the application and determine the exact torsional coupling needed for almost any application.

RUPEX^® pin and bush couplings link machine shafts and compensate for shaft misalignment with weak restorative forces.
The torque is conducted through elastomer elements, so the coupling has typically flexible rubber properties.
Thanks to their robust design, RUPEX couplings are also suitable for harsh operating conditions.
