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

Component Purpose and Material

Designed as a scale RC replacement, this tail PC bearing collar positions and supports the tail ball bearing inside the tail assembly, corresponding to the AS9 AS5T2 260Z identifiers shown in the product name. The part is produced from polycarbonate (PC) to combine dimensional consistency with convenient serviceability.

The collar serves as a bearing seat and guide, limiting radial and axial movement where the bearing meets the tail shaft or housing. Proper seating keeps tail linkage geometry stable, which supports reliable trimming and tuning of the tail section.

Installation depends on the tail housing tolerance and is typically a press-fit or slip-fit; because the part acts purely as a locator, confirm bearing clearances before final assembly. Check the collar during normal maintenance and replace it if wear starts to compromise alignment or increases play.
