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

Flanged Bearing for Small Rotor Linkages 2 x 5 x 2.3 mm

This listing contains two flanged ball bearings sized 2 x 5 x 2.3 mm for RC use. They are suitable for Hirobo helicopter components and other small linkages where the flange keeps the shaft location without added retaining hardware.

Fitting tips: remove the old bearing, make sure the bore is clean and true, and press the replacement in evenly until the flange seats. Test rotation before final assembly and take care not to apply side loads during installation to avoid damage.

Impact on handling and tuning: these bearings reduce axial play and help maintain precise shaft location, benefitting rotor linkage responsiveness, tail assembly alignment, and compact gearbox performance. Regular checks and light lubrication will keep performance consistent.
