The 204-040-131-1/204-040-130-5 is a bearing nut and shouldered shaft assembly for Bell 204-series helicopters. The nut threads onto the shaft using AS8879 UNJ form threads to lock the bearing in place and establish proper preload on rotating shafts. The machined shoulder on the shaft prevents axial movement while the threaded nut secures the bearing assembly.

Installation requires torque application per aircraft maintenance manual specifications and verification against the Illustrated Parts Catalog for compatibility. NSN 5310-00-624-5251 cross-reference.
