Positioning means for camshaft roller bearing

1. A roller bearing assembly comprising:

a plurality of rollers;

a cage including a plurality of slots for positioning the plurality of rollers;

an outer race positioned radially outside the plurality of rollers and the cage, the outer race being cylindrical; and

wherein the cage further includes two rim portions axially outward of the plurality of slots, and at least one rim portion includes an axially elastically deformable spring portion extending axially outwardly therefrom.

2. The roller bearing assembly of claim 1 , wherein at least one of the rim portions includes a radial projection configured to engage an axial end of the outer race to axially align the cage and the outer race.

3. The roller bearing assembly of claim 1 , wherein the cage further includes axial ends, at least one axial end formed with at least one wear bump.

4. The roller bearing assembly of claim 1 , wherein the roller bearing assembly is configured to support a camshaft between a first cam lobe and a second adjacent cam lobe, the cage being configured to extend an axial length that substantially fills a space between the first cam lobe and the second cam lobe.

5. A roller bearing assembly comprising:

a plurality of rollers;

a cage including a plurality of slots for positioning the plurality of rollers; and

an outer race positioned radially outside the plurality of rollers and the cage,

wherein the cage includes axial ends formed with integral positioning features, at least one axial end including at least one of axially elastically deformable spring portions extending axially outwardly therefrom and wear bumps adapted to wear away by frictional engagement with an adjacent structure extending axially outwardly therefrom.

6. The roller bearing assembly of claim 5 , further comprising means for retaining axial alignment between the cage and the outer race provided integrally with at least one of the cage and the outer race.

7. The roller bearing assembly of claim 5 , wherein the cage includes a radially extending projection that engages an end face of the outer race to retain axial alignment between the cage and the outer race.

8. The roller bearing assembly of claim 7 , wherein the cage includes a second radially extending projection engaging an opposite end face of the outer race.

9. The roller bearing assembly of claim 5 , wherein the outer race is cylindrical and not split at any point along its circumference.

10. The roller bearing assembly of claim 5 , wherein the cage includes at least one axial end formed with wear bumps.
