Durability and service notes

This RC-scale spare is supplied as two ball bearings with model number HI2500078 and dimensions 8 x 12 x 3.5 mm. They are intended for use in Hirobo helicopter general parts and other compact RC models where compact rotational bearings are required.

For longer service life, ensure bearings are pressed in squarely, shafts are true, and mating surfaces are clean. Replace bearings in matched pairs when renewing components like rotor heads or small gear trains to reduce vibration and uneven wear.

This item is provided as an RC replacement component for model upkeep and tuning only.
