SCEADU SD EX Bearing Holder HI0412254 - 19MM by Hirobo  [HI0412254]

Service replacement: bearing holder 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.

Functionally the holder locates the bearing to control axial and radial alignment, reducing excessive shaft play when correctly installed. Its contours and bolt locations are configured to match Sceadu SD EX component interfaces so geometry is preserved when substituting worn parts.

Installation guidance: confirm the correct orientation with adjacent links, trial the bearing for a secure fit before final assembly, and apply correct torque to fasteners to avoid deforming the holder. The component serves as a maintenance and tuning accessory for RC helicopter builds.

Choose this bearing holder when restoring original bearing positioning on Sceadu SD EX rotor units, and verify the seller's included items before ordering.
