WHAT IS CLAIMED IS:

1. A bearing, comprising:

a body having a first axial end and a second axial end; and at least one flange projecting radially from the second axial end of the body, wherein the at least one flange comprises a first region, second region, and a stepped transition region between the first and second regions, wherein the second region is elevated axially above the first region so as to protrude axially outwardly, wherein 1) the second region extends partially circumferentially around the flange to form at least one segment, and/or 2) the first region extends from the body to the stepped transition region and defines a maximum first axial height, htiraxi, defined as the distance from the first axial end to the maximum height of the first region, and the second region extending from the stepped transition region defines a second maximum axial height, hrnaxi, defined as the distance from the first axial end to the maximum height of the second region, and wherein hmmi < hma 2.

2. An assembly comprising:

a shaft; and

a bearing surrounding the shaft, wherein the bearing comprises:

a body having a first axial end and a second axial end; and at least one flange projecting radially from the second axial end of the body, wherein the at least one flange comprises a first region, second region, and a stepped transition region between the first and second regions, wherein the second region is elevated axially above the first region so as to protrude axially outwardly, wherein I) the second region extends partially circumferentially around the flange to form at least one segment, and/or 2) the first region extends from the body to the stepped transition region and defines a maximum first axial height, hnmxi, defined as the distance from the first axial end to the maximum height of the first region, and the second region extending from the stepped transition region defines a second maximum axial height, hnmxi, defined as the distance from the first axial end to the maximum height of the second region and wherein, hmaxi < hmax2.

3. A method for forming a bearing, comprising:

providing a blank;

forming a bearing from the blank, the bearing comprising a body having a first axial end and a second axial end; and

forming at least one flange on the second axial end of the bearing, wherein at least one flange projects radially from the second axial end of the body, wherein the at least one flange comprises a first region, second region, and a stepped transition region between the first and second regions, wherein the second region is elevated axially above the first region so as to protrude axially outwardly, wherein 1) the second region extends partially circumferentially around the flange to form at least one segment, and/or 2) the first region extends from the body to the stepped transition region and defines a maximum first axial height, hmaxi defined as the distance from the first axial end to the maximum height of the first region, and the second region extending from the stepped transition region defines a second maximum axial height, hrnaxi, defined as the distance from the first axial end to the maximum height of the second region, and wherein I i < t i.

4. The bearing, assembly, or method of any of claims 1-3, wherein the at least one segment of the second region comprises a plurality of segments.

5. The bearing, assembly, or method of any of claims 1-3 wherein the stepped transition region extends circumferentially such that the second region forms a segment adjacent the first region.

6. The bearing, assembly, or method of claim 4, wherein the plurality of

segments includes at least 3 segments.

7. The bearing, assembly, or method of any of claims 1-3, -wherein the flange comprises at least 3 stepped transition regions.

8. The bearing, assembly, or method of claim 4, wherein the plurality of

segments spans less than 270° of a circumference of the flange.

9. The bearing, assembly, or method of any of claims 1 -3, wherein hmaxi < .99 hmax2- 10. The bearing, assembly, or method of any of claims 1-3, wherein the stepped transition region has a height, hstep, of 0.05 mm to 5 mm.

1 1. The bearing, assembly, or method of any of claims 1-3, wherein the flange has a surface area, SAF, and the second region extends less than 80% of the surface area, SAF, of the flange

12. The bearing, assembly, or method of any of claims 1-3, wherein the stepped transition region is annular.

13. The bearing, assembly, or method of any of claims 1-3, wherein, as viewed in radial cross-section, the first region has a radial length, LFR, and second region has radial length, LSR, where, LFK> LSR

14. The bearing, assembly, or method of any of claims 1-3, wherein the stepped transition region forms an inclined angle Q relative to a line parallel to the central axis, wherein the inclined angle Q is in a range from at least 30 degrees to 90 degrees.

15. The bearing, assembly, or method of any of the preceding claims, wherein the bearing comprises a laminate comprising a substrate and a low friction layer.
