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 resulting in zero backlash. The coupling is made flexible by removing materials from the piece in a spiral design. Ever-power Helical Couplings are available in aluminum and stainless steel.
For position accuracy and vibration reduction in a 
servo system, these couplings solve misalignment challenges in response-mandatory servo systems designed for the
semiconductor manufacturing equipment sector, scanning equipment and many automation applications. Standard sizes available 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 application requirements. Ever-power offers many styles of versatile couplings, such as for example bellows couplings, helical couplings, Oldham couplings, general joints, and flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
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 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 swiftness torque transmission. A wide variety of bore sizes and combinations are offered to support specific needs.
