Ever-power Helical Couplings, or beam couplings, are a different 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 pattern. Ever-power Helical Couplings are available in aluminum and stainless.
For position accuracy and vibration decrease in a servo system, these couplings solve misalignment challenges in response-mandatory servo systems designed for the
semiconductor manufacturing equipment market, scanning equipment and several automation applications. Standard sizes available in bores 3 mm thru 16 mm
Commercial and Precision Helical Couplings
Flexible Couplings have the ability to compensate for shaft misalignment and so are designed to accommodate numerous kinds of load conditions. No-one type of coupling can offer the universal solution to all or any coupling problems; hence many designs are available, each possessing construction features to accommodate one or more types of software requirements. Ever-power offers many styles of versatile couplings, such as bellows couplings, helical couplings, Oldham couplings, universal joints, and flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
Ever-power Bellows Couplings are flexible couplings designed to accommodate numerous kinds of load circumstances. 
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 provide high torsional rigidity for high swiftness torque transmission. A wide variety of bore sizes and combinations are offered to support specific needs.
