Ever-power Helical Couplings, or beam couplings, are a different type of flexible coupling enabling axial movement, angular misalignment and parallel offset. This coupling style features one-piece construction leading to zero backlash. The coupling is made flexible by removing material from the piece in a spiral design. Ever-power Helical Couplings are available in aluminum and stainless steel.
For position precision and vibration decrease in a servo system, these couplings solve misalignment difficulties in response-mandatory servo systems created for the
semiconductor manufacturing equipment sector, 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 various types of load conditions. Nobody type of coupling can provide the universal answer to all or any coupling problems; hence many designs can be found, each possessing building features to accommodate one or more types of application requirements. Ever-power gives many styles of flexible 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 huge amounts of shaft misalignment combined with low resultant radial loads on the bearings. Ever-power Modular Bellows Couplings are configurable and offer high torsional rigidity for high velocity torque transmission. A wide variety of bore sizes and combinations can be found to accommodate specific needs.
