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

Details of the W-type Bearing Holder

This Hirobo spare is a W-type bearing holder for RC model helicopters, intended for repair and tuning work. It accepts a 19mm diameter bearing and provides a compact, reliable mounting point for tail or main shaft assemblies, prioritising correct fit over cosmetic alteration.

Fitment normally occurs during bearing replacement or when addressing shaft endplay. The holder gives a consistent seating surface to keep a 19mm bearing aligned under rotation, which aids tail stability and overall rotor balance.

Practical tips: after fitting, recheck shaft alignment and bearing preload, ensure there is no contact with surrounding frames or linkages, and conduct a slow spin test to confirm smooth operation. Use recommended threadlock where specified and inspect bearings at regular service intervals.

The component is compatible with Hirobo Eagle series airframes and fits Freya, EX, and SX variants that require a W-type 19mm bearing holder according to parts listings.
