Zero-Max SC035R ServoClass double-flex servo coupling, size 35, with stainless steel flex elements. Designed for high-performance servo drive systems, this coupling accommodates parallel and angular misalignment while providing torsional stiffness. The double-flex design uses two disc packs for increased offset capacity.
