Bearing Collar for Shuttle ZX 9 x 13 x 6 HI0402503 by Hirobo  [HI0402503]

Shuttle ZX Collar Specifications

This collar is made to fit Shuttle ZX installations where a 9 x 13 x 6 mm sleeve is needed to position a ball bearing. It acts as a small retention element to keep the bearing in the correct radial position inside hubs or gearbox casings on radio control helicopters.

To fit the part, seat the collar into its bore until it is flush with the mating surface, then install the bearing against it so the assembly achieves proper axial and radial alignment. Take care not to overload the part when pressing it in and confirm the bearing rotates freely after fitting to rule out any binding.

During routine maintenance the collar helps maintain consistent bearing alignment, which supports smooth rotor operation and predictable drivetrain response. Inspect for wear or distortion at the collar and bearing interface and replace if any issues are found.
