Eagle/Freya/EX/SX Pipe Drive Bearing Guide for RC Helicopters - HIROBO HI0404563  [HI0404563]

Drive pipe bearing guide summary

This RC-scale pipe drive bearing guide is designed for use in helicopter driveline assemblies. It provides a guided seat for the drive pipe and the walk-through bearing that supports the tail or main drivetrain. The unit is supplied as a single guide element to fit where the drive pipe passes through frames or bulkheads on Eagle, Freya, EX and SX series models.

Compatibility is limited to the series listed above; always verify physical fit against your airframe prior to installation. Typical replacement locates the bearing so the shaft runs concentric to the transmission, aiming to keep axial play minimal without imposing preload on the bearing.

During setup and tuning, check guide alignment with the drive shaft, confirm the bearing spins freely, and recheck set screws or retaining clips after initial flights. Inspect routinely for wear or scoring to determine when the guide or bearing should be serviced or replaced to preserve smooth driveline operation.
