BEARING

The MS21150-1 is a genuine Textron Aviation bearing — a low-friction pivot or rotational support in an assembly. It fits the 1900 Airliner, 1900C Airliner, 1900D Airliner, Bonanza 36, Bonanza F33, G33, F33A or F33C, King Air 100, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, and King Air 350i, among other compatible variants. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21150-1 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Parts like this are shared across the Beechcraft 1900, Bonanza, and King Air aircraft, reflecting how much structure and hardware these models have in common. Fit and load rating define a bearing's job, so matching the specified part protects both function and service life. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. 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. Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. The Beechcraft 1900, a 19-passenger regional airliner derived from the King Air, was produced from 1982 to 2002 and still serves commuter and cargo operators worldwide.
