Performance bearings for tuned RC setups

For competitors refining driveline efficiency, the 3RACING Double Metal Shield Bearing 1.5 x 4 x 2 mm supplies consistent rotational behaviour with low drag. These bearings suit racers seeking predictable response from wheel hubs and transmission shafts.

Shielded construction for race environments

The double metal shields reduce contaminant ingress while maintaining acceptable rotational tolerances. This balance supports repeated runs and reduces the need for frequent rebuilds between heats.

Direct fit for typical race components

With standard dimensions, these bearings slot into many race-oriented assemblies without extra machining, enabling quick swaps during setup changes or maintenance sessions.

Will these bearings reduce drivetrain losses?

Yes, replacing worn bushings or rough bearings with well-sealed metal bearings typically reduces rolling resistance and improves throttle consistency.

Are these suitable for high-rev brushless motors?

They tolerate the RPMs common in small electric rigs, but monitor temperature and replace if you notice excessive heat under prolonged high-rev conditions.

What tuning benefits do sealed bearings offer?

Sealed bearings offer consistent friction levels and better repeatability, which helps when comparing setup changes or tyre compounds between runs.
