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

10 x 22 x 6 mm shielded bearing for RC use

This Hirobo HI2500100 bearing set is supplied as 2 matched pieces, sized 10 x 22 x 6 mm for common seats in small helicopter rotors and compact RC drivetrains. These shielded ZZ bearings serve as direct replacements where that size is required, offering a low-profile solution for rotating assemblies.

Installation notes: ensure correct seating and alignment in the housing, press the bearing evenly to avoid introducing axial or radial preload, and check there is no binding after fitment. For routine maintenance, verify smooth rotation and minimal play; if one shows wear or roughness, replace both to preserve balance.

Care tips: keep debris away from the shields, avoid excess lubricant that attracts grit, and inspect after operating sessions for signs of corrosion or increased radial play. The matched pair format (2 pcs) simplifies swaps in small gearboxes and rotor supports.
