Hirobo helicopter bearing kit details

This RC accessory consists of two ball bearings listed as HI2500078, delivered as 2 pcs with dimensions 8 x 12 x 3.5 mm. They fit into Hirobo helicopter general parts and a range of small RC models that accept compact bearings for rotating components.

To fit these bearings correctly, ensure mating surfaces are free of debris and shafts are straight to reduce the chance of premature wear. Confirm the bearing seats and shaft diameters match before final installation, and replace bearings as matched pairs when overhauling rotor heads or small gearbox assemblies.

The component is supplied as an RC-scale replacement part for upkeep and tuning of models.

Which models and locations typically accept these bearings?

These 8 x 12 x 3.5 mm bearings are used in Hirobo helicopter general parts and other small RC models at compact rotor supports, small driveline points, and pivot locations sized for this bearing dimension.

Are these bearings suitable for rotor hub and linkage pivots?

Yes. Their compact 8 x 12 x 3.5 mm form factor makes them a common choice for small rotor hubs, linkage pivots, and tight drivetrain spaces where standard bearings would not fit.

How can I confirm fitment before committing to final assembly?

Measure the shaft and bore to ensure they match the 8 x 12 x 3.5 mm specification, dry-fit the bearing to check alignment, and inspect seating to avoid interference during final press-in.
