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.

Abstract: In a motor assembly, a rotor and a trigger wheel are each secured to a first race of a four-point contact ball bearing. The circumferential position of the rotor and trigger wheel are each fixed with respect to the first bearing, and therefore with respect to one another. A resolver sensor is bolted to a housing. A second race is mounted at a fixed axial position relative to the housing, thereby locating the trigger wheel with respect to the resolver sensor. In some embodiments, the first race may be an inner race and the second race an outer race. In other embodiments, the first race may be an outer race and the second race an inner race.

Abstract: An outer ring for a deep groove ball bearing assembly is disclosed. The outer ring includes a radially inner surface defining a raceway, and a radially outer surface defining a single groove extending between axial ends of the outer ring. The single groove contacts at least one axial end face of the outer ring.
