Hirobo HI2500098 2x5x2.3 mm Shielded Bearings 682ZZ Pack of 2  [HI2500098]

Precision shielded bearings for tiny shafts

These parts are identified as Hirobo HI2500098 with the 682ZZ shielded configuration, supplying two precision bearings in the compact 2 x 5 x 2.3 mm format. They are commonly used where limited space and reliable rotation are priorities.

Suitable for small helicopter components and other micro RC mechanisms that take 2 x 5 x 2.3 mm bearings, they provide a simple replacement option for bearings that have become noisy or stiff. The metal shields help keep contaminants out without a full seal.

Confirm the bearing's inner diameter suits a 2 mm shaft and that the housing will accept a 5 mm outer diameter before pressing them in. Clean the seating area, ensure the bearing is perpendicular to the bore, and check free spin by hand during trial fitment. These checks help avoid premature wear.
