Ever-power Helical Couplings, or beam couplings, are another type of flexible coupling enabling axial movement, angular misalignment and parallel offset. This coupling design features one-piece construction leading to zero backlash. The coupling is made flexible by removing materials 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 difficulties in response-mandatory servo systems designed for the
semiconductor manufacturing equipment industry, scanning equipment and many automation applications. Regular sizes available in bores 3 mm thru 16 mm
Commercial and Precision Helical Couplings
Flexible Couplings be capable 
of compensate for shaft misalignment and are designed to accommodate numerous kinds of load conditions. No-one type of coupling can offer the universal answer to all or any coupling problems; hence many designs are available, each possessing structure features to accommodate one or more types of program requirements. Ever-power gives 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 require large amounts of shaft misalignment combined with low resultant radial loads on the bearings. Ever-power Modular Bellows Couplings are configurable and provide high torsional rigidity for high speed torque transmission. A wide variety of bore sizes and combinations can be found to accommodate specific needs.
