Shuttle ZX Bearing Locator 9 x 13 x 6 - HI0402503 by Hirobo  [HI0402503]

Component Function and Use

This bearing collar is intended for Shuttle ZX assemblies requiring a 9 x 13 x 6 mm sleeve to locate a ball bearing. It performs as a compact locator sleeve that secures the bearing's radial position inside hubs or gearbox housings on RC helicopters.

Fitting normally involves pressing the collar into the bore until flush with the mating surface and then seating the bearing against it to achieve correct axial and radial alignment. Avoid excessive force when installing the sleeve and verify that the bearing rotates freely after assembly to ensure no binding has been introduced.

As part of maintenance and setup, the collar helps reduce play at the bearing interface, contributing to consistent rotor motion and predictable drivetrain performance. Regularly inspect the collar and bearing faces for wear and replace the collar if any signs of deformation are present.
