Description
The MS21432-4TEE8 is a genuine Textron Aviation roller brg supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Citation III, VI or VII. It carries an export classification of ECCN 9A991.
Because the MS21432-4TEE8 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Across the Cessna Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
A bearing or bushing sets how a shaft or pivot moves and wears; the right part keeps that motion as designed. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. Cessna's Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
