Pair of Hirobo HI2500093 Flanged Ball Bearings 2 x 5 x 2.3 mm  [HI2500093]

Flanged Ball Bearing for Compact RC Gear

These two flanged ball bearings measure 2 x 5 x 2.3 mm and are supplied for RC-scale use. They are intended for Hirobo helicopter components and other small assemblies where the flange maintains axial position without additional retaining parts.

Fitting procedure: remove the worn bearing, confirm the housing bore is clean, and press the new bearing squarely until the flange is flush with the mounting surface. Check for free, smooth rotation before completing reassembly and avoid side loading while seating the bearing.

Compatibility notes: use these bearings where accurate shaft location and minimal axial play are important, such as rotor linkages, tail units, or compact gearbox supports on small RC models. Inspect periodically and apply light lubrication suitable for model bearings to maintain performance.
