Ever-power Helical Couplings, or beam couplings, are a different type of flexible coupling allowing for axial motion, angular misalignment and parallel offset. This coupling design features one-piece construction resulting in zero backlash. The coupling is manufactured flexible by removing material from the piece in a spiral pattern. Ever-power Helical Couplings can be found in aluminum and stainless steel.
For position precision and vibration decrease in a servo program, these couplings resolve misalignment difficulties in response-mandatory servo systems created for the
semiconductor manufacturing equipment 
market, scanning equipment and many automation applications. Standard sizes available in bores 3 mm thru 16 mm
Commercial and Accuracy Helical Couplings
Flexible Couplings have the ability to compensate for shaft misalignment and so are designed to accommodate various types of load conditions. Nobody type of coupling can offer the universal solution to all coupling problems; hence many designs are available, each possessing building features to accommodate one or more types of software requirements. Ever-power presents many styles of flexible couplings, such as for example bellows couplings, helical couplings, Oldham couplings, universal joints, and flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
Ever-power Bellows Couplings are flexible couplings designed to accommodate numerous kinds of load conditions. Ever-power Hi-Flex Bellows Couplings are used for applications which need large amounts of shaft misalignment coupled with low resultant radial loads on the bearings. Ever-power Modular Bellows Couplings are configurable and provide high torsional rigidity for high rate torque transmission. A multitude of bore sizes and combinations can be found to support specific needs.
