Flanged Ball Bearing 2 x 5 x 2.3 mm (2 pcs) - Hirobo HI2500093  [HI2500093]

Compact 2 x 5 x 2.3 mm Flanged Bearing

These two flanged ball bearings are sized 2 x 5 x 2.3 mm and are suitable for small RC use. They are intended for Hirobo helicopter components and similar compact linkages where a flange helps maintain axial location without extra retainers.

Installation guidance: extract the worn bearing, clean the housing bore thoroughly, and press the replacement in straight until the flange sits flush. Confirm the rotation runs freely before putting assemblies back together, and avoid bending loads during fitment to protect the bearing.

Durability and upkeep: inspect bearings regularly and apply light lubrication suitable for model bearings to prolong service life. These parts are useful where tight axial control is needed, for example in rotor linkages and small gear supports.
