Abstract
A turbomachine roller bearing that supports a shaft constituted by a trunnion of a shaft line of a high-pressure spool of a turbomachine to rotate relative to a stationary support that is connected to a casing of the turbomachine, said bearing comprising rollers inserted between an outer ring disposed adjacent to the stationary support and an inner ring disposed adjacent to the high-pressure trunnion, the inner ring extending along the axis beyond a downstream end of the high-pressure trunnion to which it is secured by clamping means, and being provided with anti-rotation means for preventing said inner ring from rotating relative to the high-pressure trunnion.
