_X_Specific characteristics of the material or service that limit the availability to a sole source or particular brand name (unique features, function of the item, etc.).

Describe in detail why only this suggested source can furnish the requirements to the exclusion of other sources.

There are no available aftermarket Gearboxes that are interchangeable with the Betts- Bridgeford Shaft Lathe without extensive re-engineering of machine carriage traverse motion control system. The gearboxes are available through authorized distributors only. Only a Direct OEM replacement gearbox will guarantee the return of this machine to its original functional capacity with the ability to hold required precision geometric tolerances, surface finishes on manufactured production parts, and proper operation of the traverse carriage motion control system. The replacement Gearboxes must be made by the original manufacture and built to the exact specification within engineered specifications/tolerances, horsepower, torque, and overhung load ratings, manufactured out of OEM material selection to the original overall dimensions to fit into existing machine castings to connect/operate with existing Fanuc drive motor input and gearbox output shaft connections and operate in tandem with existing gearbox master/slave configuration.

Deviation from OEM specifications will render the shaft lathes south carriage Z-Axis traverse control system capabilities of this machine inoperable and detrimentally effect the Navy ability to machine main drive shafts for naval vessel overhauls.
