Claim 16:
17. An air compressor comprising:
a shaft assembly comprising:
the shaft of claim 1, wherein the shaft is centered on and extends along an axis;
a compressor rotor attached at the first attachment portion, wherein the compressor rotor is configured to compress a flow of air;
a motor attached at the second attachment portion, wherein the motor is configured to cause the shaft and compressor rotor to rotate;
a tie rod extending through the inner shaft space along the axis, wherein:
a first end of the tie rod is attached to a first retention nut and disposed at a first axial end of the shaft assembly; and
a second end of the tie rod is attached to a second retention nut and disposed at a second axial end of the shaft assembly, such that the first component, the shaft, and the second component are held in a preloaded arrangement; and

wherein the tie rod support is annular and surrounds at least a portion of the tie rod and the tie rod support is configured to reduce bending of the tie rod;
and

a housing surrounding the compressor rotor, wherein the housing defines an inlet configured to intake the flow of air and an outlet configured to output a compressed flow of air.
