Barden was founded by Theodore Barth and Carl Norden (hence the name "Bar-den") in 1942 to make precision ball bearings for the Norden bombsight. The bearings they manufactured were of exceptional quality, featuring tolerances beyond the scope of the technology then available.
In 1991, Barden became affiliated with FAG, and formed the nucleus of its Aircraft and Super Precision (ACSP)...

Repair of CFM56 #4R Bearings with Replacement of Components – Bearing Reconditioning
The CFM56 #4R main-shaft bearing is highly stressed during operation. To increase the reliability of this bearing, major design changes have been made.
Repair of Bearings with Roller Retention Cages – Bearing Reconditioning
There are many methods of cage roller retention. One of them is called staked roller retention. This type of roller retention uses tangs, formed by a special cutting tool, to retain the roller in the cage pocket.
Due to the increased risk of premature operational bearing failure, FAG strongly recommends that the practice of bending tangs is not used. FAG Repair Service will always replace this type of cage.
