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 material from the piece in a spiral design. Ever-power Helical Couplings can be found in aluminum and stainless.
For position accuracy and vibration reduction in a servo system, these couplings solve misalignment difficulties in response-mandatory servo systems made for the
semiconductor manufacturing equipment industry, scanning equipment and several automation applications. Regular 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 are designed to 
accommodate various types of load conditions. Nobody type of coupling can offer the universal option to all coupling problems; hence many designs are available, each possessing building features to accommodate a number of types of application requirements. Ever-power gives many styles of flexible couplings, such as for example 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 utilized 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 offer high torsional rigidity for high speed torque transmission. A wide variety of bore sizes and combinations can be found to support specific needs.
