Hirobo HI2500088 flanged ball bearing 8 x 16 x 5 mm, 2 pcs  [HI2500088]

Flanged Ball Bearing for RC Models

This flanged ball bearing is a small-scale RC accessory intended for general helicopter parts and other compact model assemblies. The part is supplied as a pair, 2 pcs, and the nominal inner and outer dimensions are specified in the product title to match common shaft and hub fits used in model helicopters and miscellaneous RC mechanisms.

Use in models focuses on providing a supported bearing surface where a flange helps locate the bearing axially without additional spacers. The stainless-steel race material listed in the product information targets wear resistance under typical model loads, while the flange simplifies seating into motor mounts, gear carriers, and hub assemblies.

Installation notes: press the bearing squarely into its bore until the flange seats against the mating surface, confirm free rotation on the shaft with minimal axial play, and inspect for correct alignment with mating gears or collars. Routine checks during maintenance help detect wear or contamination that can affect smooth rotation.

Tuning role: replacing worn bearings with this flanged unit can reduce side loads on shafts and improve gear mesh stability in small RC drivetrains, contributing to smoother operation and more consistent control feel in rotor and transmission components.
