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 resulting in zero backlash. The coupling is made flexible by removing materials from the piece in a spiral design. Ever-power Helical Couplings can be found in aluminum and stainless steel.
For position precision and vibration decrease in a servo program, these couplings resolve misalignment difficulties in response-mandatory servo systems created 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 have the ability to compensate for shaft misalignment and are designed to accommodate various types of load conditions. No-one type of coupling can offer the universal solution to all coupling problems; 
therefore many designs are available, each possessing building features to accommodate a number of types of program requirements. Ever-power presents many styles of flexible 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 various types of load conditions. Ever-power Hi-Flex Bellows Couplings are used for applications which need large 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 multitude of bore sizes and combinations can be found to support specific needs.
