Replacement Roller Bearings 6 x 10 x 9 mm (Hirobo HI2500018) - 2 pcs  [HI2500018]

Precision 6 x 10 x 9 bearings for compact model assemblies

This Hirobo HI2500018 set includes two 6 x 10 x 9 mm roller bearings designed for compact applications in RC helicopters and other small model components. They provide a low-profile support where close dimensional control and smooth rotation are required on small shafts and gear interfaces.

In service these bearings reduce friction at rotational junctions, stabilise shaft movement, and assist in keeping gear mesh consistent under the light loads encountered in model applications. Avoid contaminating the raceway by handling with clean tools and storing in a dust-free location.

Installation and care pointers:

• Fit: Check that the bore and shaft match the 6 x 10 x 9 mm sizing before press-fitting to prevent bearing distortion.
• Lubrication: Use a small amount of light oil or bearing lubricant to maintain smooth operation without attracting debris.
• Alignment: Seat bearings squarely to prevent side loads that lead to early wear.

Contents: two identical bearings sold together for maintenance or replacement where this size is specified.
