Hirobo HI0412254 SCEADU SD EX 19MM Bearing Mount  [HI0412254]

Hirobo bearing mount engineered for Sceadu SD EX

This bearing holder is an RC-scale replacement part labelled HI0412254 designed for Sceadu SD EX platforms, providing a dedicated mount for a 19mm bearing spacing. The description focuses on fitment role and mechanical placement within rotor-related linkages rather than performance claims.

When fitted the holder locates the bearing to control rotational alignment and reduce shaft play within normal model tolerances. Its mounting geometry is intended to replicate the original Sceadu SD EX interfaces so that alignment and component spacing are maintained during replacement.

Installation advice: make sure the holder is oriented correctly relative to nearby links, trial-fit the bearing to confirm clearance before final assembly, and tighten fasteners to recommended torque to prevent distortion or slop. This component is intended for maintenance and tuning work on RC helicopter assemblies.

Select this bearing holder when you need to restore original bearing placement on Sceadu SD EX rotor assemblies and verify what is included with the seller prior to purchase.
