Abstract: A cylindrical roller bearing includes an outer bearing ring, an inner bearing ring and cylindrical rollers located between the outer and inner bearing rings. One of the rings has side rims forming an axial stop for the cylindrical rollers. The bearing ring on which the side rims are not provided is formed with at least one groove outside the axial extension of the cylindrical rollers. A ring of spring-elastic material is positioned in the groove to form an axial stop for the cylindrical rollers. The periphery of the ring has no interruptions. To improve the running behavior of the cylindrical roller bearing, the ring possesses a V-shaped cross-section with two legs.

Abstract: A method for producing ring members, such as rings for rolling bearings, through use of a rolling operation involves warming a ring blank, positioning the warmed ring blank over a mandrel which is rotatable about a first axis, and positioning a forming roll rotatable about a second axis aligned with the first axis so as to form a rolling gap with the mandrel, with a portion of the ring blank being positioned in the rolling gap. The forming roll is driven to rotate in one rotary direction while the mandrel is driven to rotate in a rotary direction opposed to the rotary direction of the forming roll. During rotation of the forming roll and the mandrel, the mandrel is urged towards the forming roll to reduce the size of the rolling gap and thereby reduce the thickness of the ring blank while also increasing its diameter.
