Pipe Drive Bearing Guide Compatible with Eagle, Freya, EX, SX - HIROBO HI0404563  [HI0404563]

Overview of the pipe bearing guide

This item is an RC-scale pipe drive bearing guide built for helicopter driveline applications. It acts as a seating and guiding point for the drive pipe and the walk-through bearing that supports the tail or main drive train. The part is supplied as one guide element for use where the drive pipe passes through frames or bulkheads on Eagle, Freya, EX and SX series machines.

Compatibility is limited to the series listed; measure and verify fit before attempting installation. The guide normally replaces an existing unit, positioning the bearing so the shaft remains concentric with the transmission while minimising axial play and avoiding bearing preload.

After installation, rotate the drive by hand to check runout and centring, secure fasteners and recheck after the first few flights. Periodic checks for wear or scoring will show when the guide or bearing needs replacing to keep the driveline running smoothly.
