Hirobo SX 17S Bearing Holder HI0404548 19MM  [HI0404548]

Bearing holder for Hirobo SX 17S applications

The Hirobo HI0404548 bearing holder is supplied as a compact spare for SX 17S assemblies used across Eagle, Freya, EX and SX airframes. It locates and supports a 19mm bearing to help maintain correct alignment in the rotor and tail sections.

Used as the bearing seat, the holder reduces play in the transmission train when correctly installed. Ensuring the bearing is fully seated and the holder is securely fixed will reduce variability in pitch, yaw and collective settings during setup and flying.

Installation follows standard service practice for Hirobo frames: remove the necessary cover or subframe, check mating faces for wear, fit the replacement holder and confirm bearing seating and shaft runout before reassembly. Complete a ground check to ensure smooth control movement and absence of binding prior to flight.

Compatibility

• Eagle
• Freya
• EX
• SX

Choose the HI0404548 bearing holder to replace worn seating or to restore crisp transmission alignment on compatible Hirobo helicopters; always verify fit, orientation and bearing condition during service to ensure reliable control response.
