HIROBO HI0404563 Pipe Drive Bearing Guide for Eagle / Freya / EX / SX Series  [HI0404563]

What this pipe bearing guide does

This is an RC-scale pipe drive bearing guide intended for helicopter driveline assemblies. It serves as a guide and seating point for the drive pipe and the walk-through bearing that supports the tail or main drive train. The part is supplied as a single guide element to be used where the drive pipe passes through frames or bulkheads in Eagle, Freya, EX and SX series models.

Use is limited to the listed series; always confirm the guide matches your frame before fitting. Installation typically replaces an existing guide in the drive line, locating the bearing so the shaft runs concentric to the transmission and keeping axial play to a minimum without inducing preload.

During setup and tuning, verify guide alignment with the drive shaft, ensure the bearing rotates freely, and retighten or inspect retaining hardware after initial flights. Regular inspections for wear or scoring will indicate when replacement is needed to maintain smooth driveline performance.
