Shaft seal ring with anti-rotation features

Abstract

A shaft seal includes an elastomeric component that includes a plurality of anti-rotation features spaced intermittently about a circumference of the elastomeric component, and a seal contact component that is bonded to the elastomeric component. Each of the plurality of anti-rotation features is a rib structure. The rib structure of each of the plurality of anti-rotation features may extend from adjacent the outer diameter face and widen toward the inner diameter face, or may extend from adjacent the inner diameter face and widen toward the outer inner diameter face, to form substantially a tear drop shape. A shaft seal assembly includes the described shaft seal, and an application housing structure including a bore that receives at least a portion of the shaft seal. The seal contact component is received within the bore, and the application housing structure is configured to rotate relative to the shaft seal.
