Hirobo HI2500018 Bearing Set 6 x 10 x 9 mm, 2 pcs  [HI2500018]

Small-format roller bearings for model applications

The Hirobo HI2500018 set comprises two 6 x 10 x 9 mm roller bearings intended for use in compact model assemblies such as helicopters and related components. These bearings provide low-profile rotational support where accurate clearances and smooth operation are required on small shafts and gear interfaces.

When correctly installed the bearings reduce rotational friction, stabilise shaft behaviour, and support consistent gear meshing under the light loads typical of model use. Prevent contamination of the races by keeping parts clean and handling with care.

Key installation and maintenance notes:

• Fit: Ensure the shaft and housing tolerances correspond to the 6 x 10 x 9 mm dimension before pressing to avoid damaging the bearing.
• Lubrication: A small amount of light bearing oil will maintain smooth rotation without attracting excessive debris.
• Alignment: Seat the bearings correctly to avoid side loading and premature wear.

The pack includes two identical bearings sold together for replacement or maintenance where this size is required.
