Abstract
An improved arrangement and method for preventing bearing ring creep is disclosed herein. The method includes providing a bearing ring including a radial surface having at least one spiral groove. The at least one groove has edge breaks connecting lateral sides to the radial surface of the bearing ring. The method includes arranging the bearing ring inside of a housing or around a shaft such that the radial surface of the bearing ring is arranged adjacent to an inner surface of the housing or an outer surface of the shaft. The edge breaks of the bearing ring frictionally engage with the shaft or the housing to prevent creep of the bearing ring.
