CMG 1

In 2002: CMG 1 “Hard” Spin Bearing failure. This bearing suffered a failure after 1.3 years in service. The raceways, sleeve, and balls were examined after teardown.

The following improvements were suggested for CMG 1:

• Changed the sleeve material to a harder dissimilar metal other than the bearing outer race to prevent fretting and galling.

• Changed the preload nut material from A286 to a

harder 52100 to prevent wear.

CMG 3

CMG 3 failure was found as a “soft” failure. This stayed in service from Feb. 2001- Sept. 2006. The teardown analysis revealed fretting and galling.

The following improvements were suggested for CMG 3:
