A type of shaft coupling basically comprised of two hubs or flanges with a flexible metal bellows joined between them. As with all flexible shaft couplings their intent is to transmit rotary power while absorbing misalignment loads between the coupled shafts. Often referred to as “servo couplings” they are specifically used for their high level of torisional stiffness and low moment of intertia, facilitating rapid and precise transmission of angle and torque.\r\r\nApplication\r\nStepper Motor\r\nServo Motor
