Hirobo HI2521059 7 x 8 x 10 Shaft Collar for RC Helicopter Parts  [HI2521059]

Compact Collar for Shaft Location

This item is identified as HI2521059 and carries the 7 x 8 x 10 designation referenced in the product title. It is a compact locating collar intended for use in helicopter component assemblies where correct axial positioning of rotating parts supports reliable drivetrain performance.

The collar limits axial movement of shafts and helps keep linkages and gear interfaces at their intended positions during setup and flight. Before fitting, confirm the 7 x 8 x 10 marking against your helicopter's parts diagram or service manual to ensure correct fit.

Installation note: slide the collar onto the shaft, position it as required, and secure using the fastening method specified by your model; avoid over-tightening to prevent shaft damage and re-check alignment after a short trial run.
