Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial movement, angular misalignment and parallel offset. This coupling style features one-piece construction leading to zero backlash. The coupling is made flexible by removing material from the piece in a spiral design. Ever-power Helical Couplings are available in aluminum and stainless.
For position accuracy and vibration decrease in a servo system, these couplings resolve misalignment problems in response-mandatory servo systems designed for the
semiconductor manufacturing equipment sector, scanning equipment and several 
automation applications. Standard sizes obtainable in bores 3 mm thru 16 mm

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 provide the universal option to all coupling problems; therefore many designs are available, each possessing building features to accommodate a number of types of program requirements. Ever-power presents many styles of flexible couplings, such as for example bellows couplings, helical couplings, Oldham couplings, general joints, and flexible shafts

Ever-power Bellows Couplings are flexible couplings made to accommodate various types of load conditions. Ever-power Hi-Flex Bellows Couplings are utilized for applications which require huge 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 acceleration torque transmission. A multitude of bore sizes and combinations are offered to support specific needs.
Versatile Shafts are also provided by Ever-power and can be substituted instead of more costly gear trains and common joints in applications where the load must be moved in lots of directions. Flexible Shafts are stiff in torsion and very compliant in bending and lateral misalignments. They are extremely useful where in fact the load is located in a remote position requiring many equipment and shafting combinations. The basic design considerations are torque capacity, velocity, path of rotation, bend radii and services conditions.
