Ever-power Helical Couplings, or beam couplings, are a different type of flexible coupling 
allowing for axial motion, angular misalignment and parallel offset. This coupling style features one-piece construction resulting in zero backlash. The coupling is manufactured 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 resolve misalignment difficulties in response-mandatory servo systems created for the
semiconductor manufacturing equipment industry, scanning equipment and several automation applications. Standard sizes available in bores 3 mm thru 16 mm
Commercial and Accuracy Helical Couplings
Flexible Couplings have the ability to compensate for shaft misalignment and so are designed to accommodate various types of load conditions. No one type of coupling can provide the universal remedy to all coupling problems; therefore many designs are available, each possessing structure features to accommodate a number of types of program requirements. Ever-power offers many styles of flexible couplings, such as bellows couplings, helical couplings, Oldham couplings, general joints, and flexible shafts
Precision Flexible Antivibration Couplings
Commercial & Precision Flexible Couplings
Ever-power Bellows Couplings are flexible couplings made to accommodate various types of load conditions. Ever-power Hi-Flex Bellows Couplings are utilized for applications which require 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 swiftness torque transmission. A wide variety of bore sizes and combinations are offered to support specific needs.
