Claim 9:
10. A method of manufacturing a bearing support, the method comprising:
positioning a shaft such that a first end of the shaft is at least partially housed by an enclosure, wherein the shaft is configured to rotate in response to rotation of a mass mechanically coupled to a second end of the shaft opposite the first end;
on the first end of the shaft, disposing:
a first bearing,
a second bearing, and
a bearing spacer disposed between and separating the first bearing and the second bearing and comprising a first lip on a first side of the bearing spacer creating a first gap separating the first side of the bearing spacer from the first bearing and a second lip on a second side of the bearing spacer creating a second gap separating the second side of the bearing spacer from the second bearing,
wherein each of the first bearing and the second bearing comprise:
an inner ring having a first keyway and configured to rotate with the shaft,
an outer ring having a second keyway and configured to rotate with the enclosure, and
a rolling cage configured to enable the inner ring to rotate relative to the outer ring;

inserting a first key into the first keyway and a third keyway in the shaft such that the first key locks the inner rings of the first bearing and the second bearing to the shaft and causes the inner rings to rotate with the shaft; and
cooling, via airflow into and through the first gap and the second gap facilitating cooling of the first and second bearings as the shaft rotates relative to the outer rings of the first and second bearings,
wherein the enclosure houses the first and second bearings, the bearing spacer, and at least the first end of the shaft.
