Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling enabling axial movement, angular misalignment and parallel offset. This coupling style features one-piece construction resulting in zero backlash. The coupling is made flexible by removing materials from the piece in a spiral pattern. Ever-power Helical Couplings can be found in aluminum and stainless.
For position accuracy and vibration decrease in a servo system, these couplings solve misalignment difficulties in response-mandatory servo systems created for the
semiconductor manufacturing equipment market, scanning equipment and many automation applications. Standard sizes obtainable in bores 3 mm thru 16 mm
Commercial and Accuracy Helical Couplings
Flexible Couplings have the ability to compensate for shaft misalignment and are designed to accommodate various types of load conditions. No-one type of coupling can offer the universal option to all or any coupling problems; therefore many designs can be found, each possessing structure features to accommodate a number of types of application requirements. Ever-power gives many styles of versatile couplings, such as for example bellows couplings, helical couplings, Oldham couplings, general joints, and 
flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
Ever-power Bellows Couplings are flexible couplings made to accommodate numerous kinds of load circumstances. Ever-power Hi-Flex Bellows Couplings are utilized for applications which require large amounts of shaft misalignment combined with low resultant radial loads on the bearings. Ever-power Modular Bellows Couplings are configurable and provide high torsional rigidity for high velocity torque transmission. A wide variety of bore sizes and combinations can be found to support specific needs.
