SX Bearing Holder Set HI0404511 - Hirobo Fitment for Eagle, Freya, EX, SX  [HI0404511]

About SX Bearing Holders

This replacement set contains SX series bearing holders intended as common service parts for Hirobo Eagle, Freya, EX and SX model helicopters. It is sold as an accessory pack for RC-scale helicopter maintenance and should not be used on full-scale aircraft.

The holder set locates and retains ball bearings in the rotor and drive assemblies, helping to maintain correct alignment after disassembly or during rebuilds. Renewing worn holders preserves shaft concentricity and reduces play that can affect rotor tracking and handling characteristics.

Fitment notes: confirm the SX designation and match the HI0404511 part number with your parts list before fitting, verify bearing dimensions and shaft interfaces, and use appropriate fasteners and thread-locking practice for model assemblies. After assembly inspect clearances and carry out a low-throttle ground spin to ensure smooth operation prior to flight.
