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 pattern. Ever-power Helical Couplings are available in aluminum and stainless steel.
For position accuracy and vibration reduction in a servo program, these couplings resolve misalignment difficulties in response-mandatory servo systems created for the
semiconductor manufacturing equipment industry, scanning equipment and several 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 are designed to accommodate various types 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 one or more 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

Bellows Couplings are flexible couplings designed to accommodate numerous kinds of load circumstances. Ever-power Hi-Flex Bellows Couplings are used for applications which require 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 wide variety of bore sizes and combinations are offered to support specific needs.
