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

Tail Collar: Overview and Fit

This tail PC bearing collar is an RC replacement component intended to locate the tail ball bearing within the tail assembly, referenced by AS9 AS5T2 260Z in the product name. Constructed from polycarbonate (PC), the collar balances dimensional accuracy with easy handling for maintenance tasks.

As both a bearing seat and alignment ring, the collar reduces axial and radial play where the bearing interfaces with the tail shaft or housing. Accurate seating helps keep tail linkage geometry consistent, which supports stable trimming and tuning results.

Fitting is normally a press-fit or slip-fit depending on housing tolerance; because the element is positional, confirm bearing engagement and clearances before final assembly. Include the collar in routine inspections and replace it if you notice wear that affects alignment or increases play.
