6 x 10 x 9 mm Bearing Pair for Hirobo HI2500018, 2 pieces  [HI2500018]

Small-format roller bearings for model and helicopter use

The Hirobo HI2500018 bearing set is supplied as two compact 6 x 10 x 9 mm rollers intended for model-scale applications, especially where compact, low-profile supports are needed on small shafts and gear mounts. These bearings ensure precise rotation where space is limited.

When fitted correctly, the bearings reduce friction at rotating joints, stabilise shaft rotation, and help keep gear mesh consistent under the light operational loads typical of model helicopters and related kits. Protect the raceway from contamination by handling carefully and storing cleanly.

Practical fit and setup tips:

• Fit: Confirm both housing and shaft tolerances meet the 6 x 10 x 9 mm specification before pressing to avoid distortion.
• Lubrication: Apply a small amount of light bearing oil to maintain smooth rotation without collecting debris.
• Alignment: Fit the bearings squarely to prevent side loading and uneven wear.

The package contains two identical bearings sold as a set for replacement or maintenance where this size is specified.
