Helical X Series Flexible Servo Cross Slot Couplings offer a cost effective balance between couplings that are too stiff radially and those not stiff enough torsionally for servo-type applications. Helical X Series Flexible Servo Cross Slot Couplings feature high torsional stiffness, low radial loads, one piece integrity, good flexibility, and zero backlash.
Created for high performance motion control systems, Helical X Series Flexible Servo Cross Slot Couplings incorporate two flexible element sets combining greater end-to-end rotational accuracy with radial flexibility in one design. Helical X Series Flexible Servo Cross Slot Couplings are ideal for motion control applications (servo motors) and have up to 10 times greater torsional stiffness than beam types. Helical X Series Flexible Servo Cross Slot Couplings are a low cost alternative to bellows types.
