Abstract

PURPOSE:To relax an edge load acting on each part of a bearing by forming a part, which smoothly continues from a contact oval generated in a raceway groove of a bearing ring by a thrust load extending to the outside in the axial direction from a surface extending the raceway groove, in the end part of the raceway groove. CONSTITUTION:Forming a chamfered part 14 in the end part in a side of a shoulder part 13 in a raceway groove 12 of a bearing ring 11, a point A on a side surface of the raceway groove 12 is smoothly connected to a point B on the chamfered part 14 by a curved part 15 extending toward the outside in the axial direction from a surface AC extending the point A. The curved part 15 is located so as to be in a contact oval generated in the raceway groove 12 when a thrust load is applied, and a ball is prevented from derailing from the raceway groove 12. When a large thrust load is applied, the ball increases its contact angle with the outer ring 11, starting a shoulder ride moving the contact oval to the side surface of the raceway groove 12, but an edge load for the ball is moderated because of continuation by the smooth curved part AB. Accordingly, a bearing life is extended.
