Hirobo HI2500094 4x7x2.5mm Flanged Bearing - 2 pcs  [HI2500094]

Bearing features and typical applications

The Hirobo HI2500094 flanged ball bearing comes as a two pcs pack and measures 4 x 7 x 2.5 mm, suitable for compact RC linkages and rotating points. The flange gives a positive face for axial location which helps simplify assembly in tight frames and bulkheads.

Functionally, this bearing reduces rotational friction while the flange prevents lateral play. Always confirm shaft and bore measurements when fitting replacements and align the flange as per the original installation to avoid misalignment.

Care advice: clean bearings with an appropriate low-residue cleaner, then apply a light oil or a small quantity of thin grease suited for model components. Do not over-grease as excess lubricant can cause drag; replace bearings that exhibit rough rotation or excessive play.
