Hirobo HI2500100 10 x 22 x 6 mm Shielded Ball Bearing Pair  [HI2500100]

Shielded 10 x 22 x 6 mm bearings for model rotor and gearbox support

The Hirobo HI2500100 bearing pack contains two shielded ball bearings sized 10 x 22 x 6 mm, intended for small helicopter rotor mounts and other compact RC assemblies. These bearings act as direct replacements where that dimension is specified, providing a compact bearing choice for rotating parts.

Fitting guidance: confirm the housing is clean and true, press the bearing in without skewing to prevent seal damage, and check the assembly turns freely and without axial bind. For service, inspect rotation smoothness and play; replace both bearings at once if wear is present to retain even operation.

Maintenance tips: keep shields free from grit and avoid over-application of grease that can attract debris, perform routine checks after running, and replace bearings that show roughness or corrosion. The two-piece supply makes straightforward swaps in tight spaces.
