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

SX 17S bearing holder for common Hirobo platforms

The Hirobo HI0404548 bearing holder is a compact replacement part designed for SX 17S assemblies used in Hirobo Eagle, Freya, EX and SX model lines. As a common spare, it secures a 19mm-diameter bearing location in the rotor/tail geometry and helps maintain alignment under normal flight loads.

In practical use the part acts as a locating and support point for the shaft or bearing it houses. Correct seating and secure fixation reduce play in the transmission path and make subsequent pitch, yaw and collective adjustments more repeatable during setup and tuning.

Installation is straightforward for technicians familiar with Hirobo airframes: remove the affected cover or subframe, inspect mating surfaces for wear, replace the holder and verify bearing seating and shaft runout before reassembly. After installation, perform a basic preflight check to confirm there is no binding and that control linkages move smoothly through the full range.

Compatibility

• Eagle
• Freya
• EX
• SX

Use this HI0404548 bearing holder when renewing worn bearing seats or restoring tight transmission alignment on compatible Hirobo helicopter frames; verify fit and bearing orientation during service to maintain predictable flight control response.
