Hirobo HI0404619 - 19mm W-Type Bearing Holder for Eagle Series  [HI0404619]

W-Type Bearing Holder Details

This Hirobo spare component is an RC W-type bearing holder designed for maintenance and setup of model helicopters. It accepts a 19mm bearing and is positioned where a small, rigid mounting face is needed for tail or main shaft parts. The emphasis is on correct fit and replacement rather than appearance changes.

Use this holder during scheduled bearing replacement or to remedy excessive shaft endplay. It ensures a repeatable seating surface so the 19mm bearing runs true under rotation, helping to keep tail behaviour predictable and rotor balance stable.

Setup advice: check shaft alignment and bearing preload after fitting, ensure adequate clearance from frames and linkages, and perform a slow spin verification before flying. Use threadlocker on threaded fasteners if that was part of the original assembly guidance, and follow service intervals for bearing inspection.

The part is intended for use with Hirobo Eagle series airframes and is compatible with associated Freya, EX, and SX models that list a W-type 19mm bearing holder in their parts breakdown.
