These metal disc-spring couplings with
ultra-high torsional stiffness were developed for servo motor applications. The disc-spring method provides excellent properties: firmness in the torsional direction but flexibility in the
bending, step-difference, and axial directions. The disc spring that serves as the element has an unbeatable theoretically derived shape that is the result of rigorous analysis with the latest
finite element method. These couplings are available in a full line-up for many different applications. Compact and lightweight SFC models use high-strength aluminum alloy for the hub
material.
