Abstract: A stator assembly, in accordance with various embodiments, is disclosed herein. The stator assembly comprises either a first bumper or a first tab. The first bumper or the first tab extends circumferentially outward from a mating portion of the vane towards a slot in a ring. The ring may be an outer diameter (OD) ring or an inner diameter (ID) ring. The mating portion of the vane may be coupled to the ring by a potting component. The potting component may prevent direct contact between the vane and the ring.
