Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial motion, angular misalignment and parallel offset. This coupling style features one-piece construction leading to zero backlash. The coupling is manufactured flexible by removing materials from the piece in a spiral design. Ever-power Helical Couplings can be found in aluminum and stainless.
For position 
accuracy and vibration decrease in a servo system, these couplings resolve misalignment challenges in response-mandatory servo systems created for the
semiconductor manufacturing equipment industry, scanning equipment and many automation applications. Regular sizes obtainable in bores 3 mm thru 16 mm
Commercial and Accuracy Helical Couplings
Flexible Couplings be capable of compensate for shaft misalignment and so are designed to accommodate various types of load conditions. No one type of coupling can provide the universal remedy to all coupling problems; hence many designs are available, each possessing construction features to accommodate a number of types of application requirements. Ever-power presents many styles of versatile couplings, such as bellows couplings, helical couplings, Oldham couplings, common joints, and flexible shafts

Ever-power Bellows Couplings are flexible couplings made to accommodate various types of load circumstances. Ever-power Hi-Flex Bellows Couplings are utilized for applications which require large 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 swiftness torque transmission. A wide variety of bore sizes and combinations can be found to accommodate specific needs.
Flexible Shafts are also offered by Ever-power and can be substituted in place of more expensive gear trains and common joints in applications where the load must be moved in lots of directions. Versatile Shafts are stiff in torsion and incredibly compliant in bending and lateral misalignments. They are extremely useful where the load is situated in a remote placement requiring many equipment and shafting combinations. The basic design considerations are torque capacity, acceleration, path of rotation, bend radii and support conditions.
