Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling enabling 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 can be found in aluminum and stainless steel.
For position accuracy and vibration decrease in a servo system, these couplings solve misalignment issues in response-mandatory servo systems designed for the
semiconductor manufacturing equipment sector, 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 numerous kinds of load conditions. No-one type of coupling can provide the universal option to all coupling problems; hence many designs can be found, each possessing structure features to accommodate a number of types of application requirements. Ever-power offers many styles of flexible couplings, such as 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 used for applications which need 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 quickness torque transmission. A multitude of bore sizes and combinations can 
be found to accommodate specific needs.
