Abstract (en)
[origin: WO2013139514A1] The invention relates to a method for producing a rolling bearing which has an inner ring (1) with an inner ring raceway (2), an outer ring (3) with an outer ring raceway (4), and rolling bodies (5) which roll on the inner ring raceway (2) and on the outer ring raceway (4). The inner ring (1) is produced from steel and is subjected to a heat treatment which serves for hardening and which is completed with the execution of a final heat treatment step at a predefined temperature. Compressive internal stresses are formed in the inner ring (1) in a surface layer by cold working in the region of the inner ring raceway (2). The inner ring (1) is burnished after the cold working.
