Race-Oriented Shielded Bearings

The 3Racing 3RB-R166-ZZ/10 double metal shield bearings are intended for competitive and tuned hobby use, offering predictable rolling performance in a compact 3/16 x 3/8 x 1/8 form factor. They are suitable for applications where controlled bearing drag and contamination control are priorities.

Consistent Performance Under Load

The dual metal shields reduce ingress of track debris while maintaining stable rotation characteristics, which helps sustain predictable tyre and drivetrain response in race environments.

Fitment and Setup Notes

These bearings are compatible with common hub bores and motor mounts that accept the 3/16 x 3/8 x 1/8 sizing. For optimal results, ensure housings are clean, press bearings squarely, and verify endplay where applicable to your suspension or gearbox layout.

What clearance should I expect when swapping bearings?

Confirm the hub and shaft tolerances for your specific model; these bearings follow standard 3/16 inner and 3/8 outer dimensions, so clearance depends on your chassis tolerances and press fit method.

Are these bearings suitable for pinion and spur alignment?

They can be used in gearbox idlers and wheel hubs where the size matches; ensure axial play is controlled in your drivetrain to prevent misalignment under load.

Maintenance best practices for race use?

Inspect bearings between heats, keep housings clear of grit, and perform light cleaning and relubrication if lap times drop or bearing noise appears. Replace bearings that show roughness to preserve performance consistency.
