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

Tail Collar Technical Notes

A scale RC replacement, the JR Propo JR70529 tail PC bearing collar locates and supports the tail ball bearing within the tail assembly, matching the AS9 AS5T2 260Z designation. Polycarbonate (PC) provides dimensional stability while allowing straightforward servicing during routine maintenance.

The collar operates as a seating surface and alignment guide to minimise axial and radial play where the bearing meets the tail shaft or housing. Correct seating preserves tail linkage geometry so trim adjustments behave predictably.

Installation is determined by housing tolerance and is normally a press-fit or slip-fit; because the component is positional, ensure the bearing is seated correctly and clearances are acceptable before final assembly. Replace the collar if wear impairs alignment or increases play.
