Hirobo HI2521106 Shaft Collar 3 x 6 x 10.4  [HI2521106]

Shaft collar for micro RC helicopters

This Hirobo collar is an RC-scale shaft collar measuring 3 x 6 x 10.4 as listed in the product name. It is intended for general helicopter components where a compact locating element is required, acting as a simple mechanical stop and an alignment aid to keep parts positioned on slim shafts during routine adjustments.

Installation is straightforward: slide the collar onto the target shaft, set it to the required location and secure using your model's fastening method. Tighten set screws gradually to avoid crushing or scoring the shaft and confirm fit and clearance before final assembly. As a generic collar, always verify shaft diameter and available clearance in your model before use.

During setup and tuning the collar can serve as a precise spacer for small positional changes, handy when adjusting rotor linkages or mounting accessories. It is supplied as a single unit intended for RC model-scale maintenance and alignment tasks.
