Hirobo HI2500056 Precision 5 x 8 x 2.5 mm Ball Bearings Pack of 2  [HI2500056]

Durable 5 x 8 x 2.5 mm bearing pair

The Hirobo HI2500056 bearings are supplied as two precision 5 x 8 x 2.5 mm units designed to withstand the demands of small RC helicopter rotating points, including rotor heads and gear carriers.

Compatibility is confirmed by matching inner and outer diameters and the width to the original item. When fitting, ensure the bearing is pressed straight and evenly into place to avoid race or ball damage. Only use these bearings where the 5 x 8 x 2.5 mm size is required.

These bearings help lower friction and preserve shaft alignment. Regularly inspect for roughness or axial play and replace worn bearings as a set; apply a light, appropriate lubricant during reassembly to extend service life.
