As you probably know, compact friction springs improve damping performance and give off high kinetic energy in a wide range of mechanical systems. Wabtec Corporation experienced this first-hand when they used our friction springs in their mechanical couplers for trains.

 Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be overengineered with regard to stiffness.

Ringfeder Power Transmission's new RfN 5571 series of flange couplings for heavy duty applications offer easy installation and have higher torque capacity than standard press fits.
