Abstract
An angular type ball bearing according to the present invention secures good property of lubricating a shaft to be supported by the ball bearing while reducing the manufacturing cost thereof, thereby being able not only to reduce the temperature rise of the bearing as well as the required rotation torque of the shaft to be supported but also to enhance the running accuracy of the shaft to be supported. The anti-load-side end portions of the outer rings of the bearings are respectively situated nearer to balls arranged along the axial direction of a shaft to be supported by the bearings than the load-side end portions of the inner rings of the bearings . The width-direction dimensions of the outer rings are formed smaller than the width-direction dimensions of the inner rings
