Hirobo HI2500045 6 x 15 x 5 mm 696ZZ Shielded Ball Bearings 2pcs  [HI2500045]

Shielded 696ZZ Bearings for Model Helicopter Use

This Hirobo replacement set provides two 696ZZ shielded ball bearings sized 6 x 15 x 5 mm for use in RC helicopter repair and small drivetrain work. The double metal shields protect the race from debris while preserving low friction for rotating parts at scale.

Fitment guidance: these bearings match shafts and housings calling for 6 x 15 x 5 mm bearings, commonly employed in rotor heads, compact gearboxes, and motor shaft supports on electric RC helicopters. Use them where the original bearing dimensions and shield type align.

Fitting and tuning advice: press the bearing into place using a tube or bearing driver that bears on the outer race only; do not hammer the inner race. Ensure a smooth free-spin after installation. Replacing worn bearings can reduce play and vibration, aiding smoother rotor operation and improved control response.

Care and upkeep: keep spares clean and, if required, apply light model oil. Avoid heavy greases which attract dust, and check bearings periodically for roughness or lateral play as indicators for replacement.
