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.

For applications with diesel, gasoline or natural gas engines which drive one or more flange-mounted hydraulic pumps.
Low weight, high torsional stiffness and long service life.
» Maintenance-free.
» Series for SAE flywheels.
» Multiple or single units available.


» Solve torsional vibration problems within Diesel engine applications.
» Torsionally flexible or rigid dependant on application.
» Low weight, low moment of inertia.
» Small overall length aids equipment design.
» Enables disassembly without moving driver/driven equipment.
» Flanged versions suit SAE standard and non-standard arrangements.
» LM series design protects driver/driven equipment under stall conditions.
