Hirobo HI2500100 10 x 22 x 6 mm Bearings, Shielded, 2 pcs  [HI2500100]

Precision 10 x 22 x 6 mm ball bearings for small RC gear

This Hirobo HI2500100 set provides two shielded 10 x 22 x 6 mm bearings intended for use in small helicopter rotor supports and compact RC drivetrains. They function as direct replacements where that bearing size is required, offering a compact, low-profile option.

Installation pointers: ensure the bore and housing are free of burrs, press each bearing straight and evenly, and check there is no axial restriction once fitted. For tuning and upkeep, feel for smooth rotation and minimal radial play; replacing the matched pair keeps assemblies balanced.

Service advice: keep the shields clean and avoid excess lubricant that traps grit, inspect after operating sessions, and replace bearings with signs of roughness, corrosion, or increased play. The pair format (2 pcs) allows simple one-to-one replacements in small gearboxes and rotor supports.
