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

Compact Flanged Bearing for Small 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.

In service, the flange provides an axial locating surface so the bearing can be seated without extra spacers. The stainless steel race material described in the listing is chosen to resist wear under normal model loads, while the flange aids seating into motor mounts, gear carriers, and hub assemblies.

For installation, press the bearing squarely into the bore until the flange seats against the mating surface, verify free rotation on the shaft with minimal axial play, and check alignment with mating gears or collars. Regular inspections will reveal wear or contamination that can affect smooth rotation.

Replacing worn bearings with this flanged unit can reduce side loads on shafts and help stabilise gear mesh in small drivetrains, aiding smoother operation in rotor and transmission parts.
