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

Tail Bearing Collar Overview

This tail PC bearing collar is an RC-scale replacement part intended to locate and support the tail ball bearing inside the tail assembly, as identified by the AS9 AS5T2 260Z designation in the product name. The main body material is polycarbonate (PC), which balances dimensional stability with serviceability for routine maintenance and occasional disassembly.

In practice the collar serves as a bearing seat and alignment guide, reducing axial and radial play where the bearing interfaces with the tail shaft or housing. Proper seating helps keep tail linkage geometry consistent, which in turn supports predictable trimming and tuning of the tail section during setup.

Installation is typically a press-fit or slip-fit operation depending on the tail housing tolerance; the part’s role is purely positional, so confirm bearing fit and clearances before reassembling the tail unit. Inspect the collar and bearing during regular maintenance intervals and replace if you notice wear that affects alignment or increases play.
