Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial motion, angular misalignment and parallel offset. This coupling design features one-piece construction leading to zero backlash. The coupling is manufactured 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 precision and vibration reduction in a servo system, these couplings solve misalignment problems 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 Accuracy Helical Couplings
Flexible Couplings be capable of compensate for shaft misalignment and so are designed to accommodate various types of load conditions. Nobody type of coupling can provide the universal solution to all or any coupling problems; therefore many designs are available, each possessing structure features to accommodate a number of types of application requirements. Ever-power offers many styles of versatile 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 numerous kinds 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 accommodate specific needs.
