Description
The MS21233-8 is a genuine Textron Aviation bearing that supports rotational or pivoting motion within a mechanism. It is applicable to the Beechjet 400/400A. It carries an export classification of ECCN 9A991.
Because the MS21233-8 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 Beechcraft fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Fit and load rating define a bearing's job, so matching the specified part protects both function and service life. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. The Beechjet 400, which began life as the Mitsubishi Diamond and later became the Hawker 400, is a light business jet supported today through Textron Aviation.
