AS9 AS5T2 260Z Tail PC Bearing Collar JR70529 JR Propo  [JR70529]

Tail Collar Function and Fit

This tail PC bearing collar is a scale RC replacement that positions and supports the tail ball bearing within the tail assembly, matching the AS9 AS5T2 260Z reference in the product name. It is moulded from polycarbonate (PC) to provide stable dimensions while remaining serviceable for routine maintenance and occasional disassembly.

The collar functions as a seating surface and alignment guide, reducing axial and radial play where the bearing interfaces with the tail shaft or housing. Correct seating helps maintain tail linkage geometry so trimming and tuning remain predictable during setup.

Depending on tail housing tolerances, installation is typically a press-fit or slip-fit; because the part is purely positional, verify bearing fit and clearances before final assembly. Inspect the collar and bearing at scheduled maintenance intervals and replace if wear begins to affect alignment or introduce excess play.
