19mm Bearing Holder for SCEADU SD EX - HI0412254 Hirobo  [HI0412254]

Replacement bearing mount 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.

In practice the holder secures a bearing where rotational load and alignment matter, helping to locate the bearing and keep shaft play within expected model tolerances. The shape and mounting points are intended to match the Sceadu SD EX component interfaces to maintain correct geometry when replacing worn parts.

For installation, verify orientation of the holder relative to adjacent links and fasteners, confirm bearing fit before final assembly, and use appropriate torque on fasteners to avoid deforming the holder or introducing play. The part is a structural accessory intended for model maintenance and tuning tasks on RC helicopter assemblies.

Use this bearing holder when matching replacement geometry is required on Sceadu SD EX RC helicopter assemblies, and confirm included components with the vendor before purchase.
