Abstract
A bearing component has a raceway face and a non-functional face different from the raceway face, and at least one first portion of the non-functional face is laser-hardened. Also a method that includes providing a bearing component having a raceway face and a non-functional face different from the raceway face and laser hardening at least one first portion of the non-functional face.
Claims19
A bearing component comprising:
- a raceway face, and
- a non-functional face different from the raceway face,
- wherein at least one first annular portion of the non-functional face is laser-hardened,
- wherein at least one second annular portion of the non-functional face is not hardened,
- wherein the at least one first annular portion of the non-functional face is adjacent to the at least one second annular portion of the non-functional face, and
- wherein the at least one first annular portion of the non-functional face is raised relative to the at least one second annular portion of the non-functional face.

A bearing component comprising:
- a raceway face, and
- a non-functional face different from the raceway face,
- wherein at least one first portion of the non-functional face is laser-hardened,
- wherein at least one second portion of the non-functional face is not hardened,
- wherein the at least one first portion of the non-functional face has a first coefficient of friction and the at least one second portion of the non-functional face has a second coefficient of friction less than the first coefficient of friction,
- wherein the at least one first portion of the non-functional face comprises a first first portion and a second first portion and the at least one second portion of the non-functional face is located between the first first portion and the second first portion, and
- wherein the at least one first portion is raised relative to the at least one second portion to form a channel.

A method comprising:
- providing a bearing component having a raceway face and a non-functional face different from the raceway face, and
- laser hardening at least one first annular portion of the non-functional face while leaving at least one second annular portion of the non-functional face unhardened,
- wherein the at least one first annular portion of the non-functional face is adjacent to the at least one second annular portion of the non-functional face, and
- wherein the at least one first annular portion of the non-functional face is raised relative to the at least one second annular portion of the non-functional face.
