A bearing assembly support and adjustment system includes an annular support device and an annular adjustment sleeve. The annular support device has a support device outer circumferential surface located about a first axis and a support device inner circumferential surface located about a second axis spaced apart from the first axis. The annular adjustment sleeve has an adjustment sleeve outer circumferential surface located about a third axis and an adjustment sleeve inner circumferential surface located about a fourth axis spaced apart from the third axis. The annular adjustment sleeve is coupled to the annular support device with the adjustment sleeve outer circumferential surface located immediately adjacent the support device inner circumferential surface.

1. A bearing assembly support and adjustment system, comprising: an annular support device having a support device outer circumferential surface located about a first axis, and a support device inner circumferential surface located about a second axis spaced apart from the first axis;an annular adjustment sleeve having an adjustment sleeve outer circumferential surface located about a third axis and an adjustment sleeve inner circumferential surface located about a fourth axis spaced apart from the third axis, wherein the annular adjustment sleeve is coupled to the annular support device with the adjustment sleeve outer circumferential surface located immediately adjacent the support device inner circumferential surface; anda clamp member located in a clamp channel defined by the annular support device, the clamp member being coupled to the annular support device and being operable to provide a radial force to the annular support device directed towards the first axis. 2. The system of claim 1, wherein the annular support device further comprises a plurality of spring portions extending between the support device inner circumferential surface and the support device outer circumferential surface, the plurality of spring portions being adapted to deflect a load force from a shaft disposed within the annular support device. 3. The system of claim 1, further comprising a plurality of support device index slots defined by the annular support device. 4. The system of claim 3, further comprising a plurality of adjustment sleeve index slots defined by the annular adjustment sleeve, wherein with the annular adjustment sleeve coupled to the annular support device, at least one of the plurality of adjustment sleeve index slots is located adjacent at least one of the plurality of support device index slots. 5. The system of claim 1, wherein the annular support device is operable to be rotated relative to the annular adjustment sleeve in order to move the fourth axis along a line relative to the first axis. 6. A shaft support and adjustment system, comprising: a bearing coupled to a housing and defining a bore having a shaft located therein; anda support and adjustment device located between the housing and the bearing, wherein the support and adjustment device comprises: an annular support device having a support device outer circumferential surface located about a first axis and engages the housing and a support device inner circumferential surface located about a second axis spaced apart from the first axis, wherein a plurality of spring portions extend between the support device inner circumferential surface and the support device outer circumferential surface;an annular adjustment sleeve having an adjustment sleeve outer circumferential surface located about a third axis and engages the support device inner circumferential surface, and an adjustment sleeve inner circumferential surface that engages the bearing and is located about a fourth axis spaced apart from the third axis, wherein the annular support device is operable to be rotated relative to the annular adjustment sleeve in order to move the fourth axis along a line relative to a perimeter of the annular support device; anda clamp member disposed in a clamp channel defined by the annular support device, the clamp member being coupled to the annular support device and being operable to provide a radial force to the annular support device directed towards the first axis. 7. The system of claim 6, wherein the plurality of spring portions comprise a plurality of first spring portions having a first stiffness and a plurality of second spring portions having a second stiffness, and wherein the second stiffness is greater than the first stiffness. 8. The system of claim 6, further comprising a plurality of support device index slots defined by the annular support device. 9. The system of claim 8, further comprising a plurality of adjustment sleeve index slots defined by the annular adjustment sleeve, wherein a securing member is located in at least one of the plurality of support device index slots and at least one of the plurality of adjustment sleeve index slots in order to prevent rotation of the annular adjustment sleeve relative to the annular support device. 10. The system of claim 6, wherein the clamp channel extends into the annular support device from a substantially central location on the support device outer circumferential surface, and wherein the clamp member is disposed in the clamp channel such that a clamp member outer circumferential surface is located adjacent the support device outer circumferential surface. 11. The system of claim 6, wherein the line along which the fourth axis moves in response to rotation of the annular support device relative to the annular adjustment sleeve comprises a vertical line that extends radially from the fourth axis prior to rotation of the annular support device relative to the annular adjustment sleeve, and wherein the rotation of the annular support device relative to the annular adjustment sleeve prevents the fourth axis from moving along a horizontal line in a direction perpendicular to the vertical line. 12. A method for supporting and adjusting a shaft, comprising: providing an annular support device coupled to an annular adjustment sleeve, wherein the annular adjustment sleeve defines an adjustment sleeve bore operable to receive the shaft;deflecting the annular support device with a load of the shaft to determine an offset of a shaft axis relative to a desired axis when the shaft is positioned in the adjustment sleeve bore;rotating the annular support device relative to the annular adjustment sleeve in order to move an axis of the adjustment sleeve bore such that the offset of the shaft axis relative to the desired axis is reduced when the shaft is positioned in the adjustment sleeve bore; andpositioning a clamp member in a clamp channel defined by the annular support device. 13. The method of claim 12, further comprising tightening the clamp member to secure the position of the annular support device and the annular adjustment sleeve. 14. The method of claim 12, further comprising positioning a securing member in at least one support device index slot and in at least one adjustment sleeve index slot in order to prevent rotation of the annular adjustment sleeve relative to the annular support device. 15. The method of claim 12, wherein rotating the annular support device relative to the annular adjustment sleeve in order to move an axis of the adjustment sleeve bore such that the offset of the shaft axis relative to the desired axis is reduced comprises moving the axis of the adjustment sleeve bore along a line relative to a perimeter of the annular support device. 16. The method of claim 12, further comprising: positioning a bearing that defines a bearing bore in the adjustment sleeve bore;positioning the annular support device, the annular adjustment sleeve, and the bearing in a housing;positioning the shaft in the bearing bore; andsupporting the shaft, wherein the moving of the axis of the adjustment sleeve bore positions the shaft axis along the desired axis.
