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

Ball bearing 5 x 8 x 2.5 mm, two pieces

The Hirobo HI2500056 is provided as a pair of 5 x 8 x 2.5 mm ball bearings intended for small RC helicopter rotating points including rotor heads and gear carriers when that bearing size is required.

Compatibility is established by matching inner diameter, outer diameter and width to the original part. During installation, align and press the bearing straight into the shaft or housing and apply steady force; avoid angling the bearing to prevent damage to the race or the balls. Use this component only where 5 x 8 x 2.5 mm is specified.

Bearings reduce friction and help sustain shaft concentricity. Inspect for roughness or play and replace both bearings when wear is apparent; apply a light lubricant suited for small RC bearings as part of routine maintenance.
