Hirobo HI2500056 Replacement Ball Bearing 5 x 8 x 2.5 mm, 2 pcs  [HI2500056]

Replacement bearing 5 x 8 x 2.5 mm — pair

The Hirobo HI2500056 is supplied as a matched pair of 5 x 8 x 2.5 mm ball bearings intended for small RC helicopter rotating assemblies such as rotor heads and gear carriers.

Fitment relies on matching the bearing inner diameter, outer diameter and width to the original part. For installation, press the bearing squarely onto the shaft or into its housing using even pressure; do not tilt or lever at an angle to avoid damaging the race or balls. Use this component only where a 5 x 8 x 2.5 mm bearing is specified.

During routine service these bearings reduce friction and help maintain shaft concentricity. Check for play or roughness and replace bearings in matched pairs when wear is present, applying a light lubricant made for small RC bearings to keep operation smooth.
