Abstract

A bearing including a substrate layer including an aluminum alloy including a thickness, T S , where T S ≤0.6 mm; an adhesive layer; and a low friction material layer overlying the adhesive layer, where the bearing includes an elongation at break, A 50 , of ≥23%.

Claims (24)

1. A bearing comprising:

a substrate layer;

an adhesive layer; and

a low friction material layer overlying the adhesive layer, wherein the bearing comprises an elongation at break of≥23%, wherein the substrate layer comprises an aluminum alloy comprising:

96.8-99 wt % aluminum,

0.05 to 0.20 wt % copper,

0-0.70 wt % iron,

1 to 1.5 wt % manganese,

0-0.6 wt % silicon, and

0-0.1 wt % zinc, wherein the bearing has a thickness of greater than or equal to 0.1 mm and less than 0.5 mm, wherein the bearing comprises an axial bearing portion and radial flange.

2. The bearing off claim 1 , wherein the bearing comprises a tensile strength having a value of between about 90 N/mm 2 to about 140 N/mm 2 .

3. The bearing of claim 1 , wherein the bearing comprises a yield point having a value of≥35 N/mm 2 .

4. The bearing of claim 1 , wherein the adhesive layer is disposed between the substrate and the low friction material layer.

5. The bearing of claim 4 , wherein the adhesive layer has a thickness of between 0.02 mm and 0.1 mm.

6. The bearing of claim 4 , wherein the adhesive layer comprises a fluoropolymer.

7. The bearing of claim 1 , wherein the low friction layer has a thickness of between 0.05 mm and 0.25 mm.

8. The bearing of claim 1 , wherein the substrate layer has a thickness between about 350 microns and 450 microns.

9. The bearing of claim 1 , wherein the low friction material layer comprises a fluoropolymer.

10. The bearing of claim 1 , wherein the low friction material layer comprises polytetrafluoroethylene.

11. The bearing of claim 1 , wherein the radial flange comprising an axial split.

12. The bearing of claim 1 , wherein bearing comprises an axial gap in the axial bearing portion.

13. The bearing of claim 1 , wherein bearing has an inner radius of 2.5-20 mm.

14. The bearing of claim 1 , wherein bearing has an outer diameter of 5-25 mm.

15. The bearing of claim 1 , wherein bearing has a length of 5-50 mm.
