Hirobo 694ZZ Shielded Ball Bearings 4x11x4 mm HI2500095, Pack of 2  [HI2500095]

Precision sealed bearings 4x11x4 mm - 2-pack

The Hirobo HI2500095 comprises two sealed ball bearings at 4 x 11 x 4 mm, identified with code #694ZZ for shielded protection. Intended as an aftermarket replacement for small-scale RC drivetrains and rotor hubs, this pair offers a compact, low-profile option where space and sealing matter.

These bearings help lower friction and restore smooth rotation when a factory bearing becomes rough or loose. Fit each bearing squarely into its housing and inspect the mating shaft for nicks; after pressing in, check for unwanted axial or radial movement to confirm a snug fit.

Care guidance: shielded bearings like these resist light contamination but still benefit from periodic checks and replacement when wear shows. Match the original part by ordering HI2500095 or #694ZZ to ensure correct size and shield style.
