Flanged Ball Bearing Set 8 x 16 x 5 mm Hirobo HI2500088, 2 pcs  [HI2500088]

Small Flanged Bearing — Installation and Use

This flanged ball bearing serves as a compact RC component for helicopter parts and other small-scale model assemblies. It comes as a pair (2 pcs), and the inner and outer dimensions are indicated in the product title to match common shafts and hubs used in model rotorcraft and similar mechanisms.

The flange gives an axial locating face to secure the bearing without additional retaining spacers. Stainless steel races are specified for improved wear resistance under typical model loads, and the flange simplifies fitting into motor mounts, gear carriers, and hub assemblies.

Installation tip: use a press or a carefully aligned driver to push the bearing into its bore until the flange sits flush with the mating surface, confirm the shaft spins freely with minimal endplay, and ensure gear alignment to prevent premature wear. Periodic checks will detect debris or wear that can hinder rotation.

In tuning contexts, replacing tired bearings with these flanged units can cut down lateral loads on shafts and stabilise gear engagement in small drivetrains, resulting in steadier operation of rotor and transmission elements.
