Hirobo HI2521060 2 x 3 x 1.2 Shaft Locator Collar for RC Helicopters  [HI2521060]

Precision locator for Hirobo model assemblies

The HIROBO HI2521060 collar is a small-scale shaft collar intended for service and assembly on Hirobo helicopter models. The printed dimensions 2 x 3 x 1.2 describe the collar's nominal size for accurately placing and retaining shafts and linkages in tight subassemblies.

Functionally the collar prevents axial movement and maintains indexing for servos, bellcranks, and rotating shafts. As a maintenance-level part it helps reduce unwanted play and supports correct geometry when adjusting controls or performing minor repairs.

To install, position the collar on the shaft at the required point, align the related components, then secure using the model's set screw or fastening method. Avoid excessive torque on the fastener to protect the shaft surface, and recheck alignment and runout if precise balance is needed.

Intended for model repairs and tune-ups, the collar is supplied as an RC accessory for routine use.
