Precision Bearings for Tuned RC Setups

The 3RACING 5x11x3mm double metal shield bearings are intended for fine-tuned racing components where low drag and repeatable behaviour matter. They provide consistent rolling resistance suitable for gearbox and wheel hub applications in competitive builds.

Shield Design and Serviceability

Double metal shielding reduces ingress of abrasive particles while keeping internal lubrication more stable than open bearings. This balance aids longevity under race weekend conditions and simplifies inspection intervals.

Applications in Racing Builds

These bearings are appropriate for use in hubs, driveshafts and small gearbox assemblies in tuned models. Supplied in pairs, they are convenient for front or rear replacements during setup changes or when optimising spin-down performance.

What is the best maintenance approach for racing use?

Inspect regularly for roughness and remove embedded debris using solvent spray; relubricate lightly with a low-viscosity bearing oil to maintain low drag.

Are these suitable for high-RPM gearbox testing?

Yes, their metal shields help at higher rpm by limiting contamination entry, but monitor temperature and endplay under sustained high-load runs.

How should I choose between shielded and sealed bearings for a race car?

Choose shielded bearings like these when you prioritise minimal drag and predictable spin; opt for rubber-sealed units if you expect heavy water or mud exposure.
