Toyota 9009910227 — Alternator Bearing
Overview
Alternator bearing Toyota 9009910227 supports the alternator rotor shaft, allowing smooth rotation inside the housing without axial play or friction. This genuine single-row deep groove ball bearing is manufactured from hardened high-carbon bearing steel to withstand high thermal loads and mechanical stress under high engine speeds. The assembly features double-lip synthetic rubber contact seals on both sides to retain factory-filled high-temperature lithium grease while excluding road dust, dirt, and water from internal raceways. Technical specifications include an outer diameter of 35 mm, an inner diameter of 15 mm, and a total width of 13 mm. This component corresponds to OEM reference number 90099-10227, as well as cross-references Koyo 6202DG8, NSK B15-69, Denso 021580-4510, and WAI 6-202-4W.
Fitment covers Toyota passenger cars and commercial vehicles including Corolla, Camry, RAV4, Hilux, Land Cruiser Prado, Avensis, Yaris, and Auris fitted with original 12 V Denso alternators. Replacement is required when experiencing high-pitched whining, grinding noises, pulley play, elevated operating temperatures, or shaft binding during alternator operation. Installing this original factory specification bearing eliminates unwanted mechanical noise and restores correct internal rotor clearance across all operating speed ranges.
