Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial movement, 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.

For position precision and vibration reduction in a servo system, these couplings solve misalignment challenges in response-mandatory servo systems created 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 are designed to accommodate numerous kinds of load conditions. No one type of coupling can provide the universal answer to all coupling problems; hence many designs can be found, each possessing construction features to accommodate a number of types of program requirements. Ever-power gives many styles of flexible couplings, such as bellows couplings, helical couplings, Oldham couplings, common joints, and flexible shafts

Ever-power Bellows Couplings are flexible couplings made to accommodate numerous kinds of load conditions. Ever-power Hi-Flex Bellows Couplings are used 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 speed torque transmission. A wide variety of bore sizes and combinations can be found to support specific needs.

Flexible Shafts are also offered by Ever-power and may be substituted instead of more costly gear trains and general joints in applications where in fact the load must be moved in many directions. Flexible Shafts are stiff in torsion and very compliant in bending and lateral misalignments. They are really useful where in fact the load is located in a remote placement requiring many equipment and shafting combinations. The basic design considerations are torque capacity, acceleration, path of rotation, bend radii and assistance conditions.
