Combining polymer resin bellows and zero backlash aluminum hubs, BELLOWFLEX Couplings allow angular misalignment up to 10° and handle shaft speeds from 5,500–9,000 rpm, depending on model. Electrically insulating bellows prevents electrical current from passing between system shafts through coupling. Available in 3 sizes, with bore range of 3–18 mm, couplings are suited for stepper motor and encoder applications providing radial flexibility.
