Hirobo HI2521096 Shaft Collar — Compatible Part for Hirobo Helicopter General Parts  [HI2521096]

Hirobo rotor shaft collar details

The Hirobo HI2521096 collar is an RC-scale shaft collar intended for Hirobo helicopter general parts. It functions as a small mechanical clamp to keep components located on a shaft and to maintain axial spacing within rotor-related assemblies. Below are compatibility pointers, fitment checks, and its role in setup operations.

Compatibility: because it is catalogued under Hirobo helicopter general parts, the collar is suitable where the specified dimensions match the shaft and adjacent components. Measure the shaft and confirm clearance with surrounding parts before installing to ensure correct fit and operation.

Installation and service role: install the collar at the required axial position and secure it so the retained component cannot move during rotation. Common uses include locking gear or spacer positions, stabilising rotor spacing, and helping with repeatable alignment when setting tracking or drive tolerances. Inspect for burrs or deformation during servicing and replace if the fit or clamping capability is impaired.
