Description

The PF Series (PowerFlex) power transmission coupling uses the proven HELI-CAL Flexure to provide reliable torque transmission between shafts, while allowing for substantial angular and parallel misalignment compensation. The PF Series also incorporates the convenience of interchangeable bushings, providing for quick and easy changes in bore sizes, while using the same HELI-CAL FLEXIBLE COUPLING center section. This means both fast initial delivery (separate bushings and center section are assembled for shipment from inventory), and the ability to change the coupling's bore sizes without remachining when the coupling is already in use (just order new bushings precision bored to your needs).

To make things even simpler, the need for keyways has been eliminated. By designing the tapered bushings to hold more torque than the maximum torque capacity of the coupling, sizing and placement of keyways is no longer an issue. The PF Series is available in both aluminum and corrosion resistant steel (CRES).
