Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial motion, angular misalignment and parallel offset. This coupling design features one-piece construction leading to zero backlash. The coupling is made flexible by removing material from the piece in a spiral pattern. Ever-power Helical Couplings are available in aluminum and stainless steel.
For position precision and vibration reduction in a servo program, these couplings solve misalignment problems in response-mandatory servo systems designed for the
semiconductor manufacturing equipment market, scanning equipment and several automation applications. Regular 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; hence many designs are available, each possessing construction features to accommodate one or more types of application requirements. Ever-power presents many styles of versatile couplings, such as for example bellows couplings, helical couplings, Oldham couplings, common joints, and flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
Ever-power Bellows Couplings are flexible 
couplings designed to accommodate various types of load conditions. Ever-power Hi-Flex Bellows Couplings are utilized for applications which need huge amounts of shaft misalignment coupled with low resultant radial loads on the bearings. Ever-power Modular Bellows Couplings are configurable and offer high torsional rigidity for high acceleration torque transmission. A multitude of bore sizes and combinations can be found to accommodate specific needs.
