Method for producing a track element of a bearing assembly
Abstract:
A method for manufacturing a raceway element of a bearing assembly includes hardening a raceway element having a raceway surface by at least partially heating the raceway element, deep rolling the raceway surface using a first rolling element, and then deep rolling the raceway surface using a second rolling element. The first rolling element has at least one different dimension than the second rolling element. In the resulting raceway element, compressive residual stresses of at least 400 MPa are present at a depth from the raceway surface of 200 μm or less, and between the raceway surface and a depth of 100 μm from the raceway surface, the amount of the compressive residual stresses changes by 500 MPa or less.
