Improve Drive Smoothness with 3RACING 3RB-MR84-ZZ/2

If you want consistent rolling performance, the 3RACING Double Metal Shield Bearing in 4x8x3mm format is a no-nonsense choice. Sized to fit a range of common shafts and hubs, this 2 piece set helps reduce friction and extends component life when fitted correctly.

Shielded Construction for Longer Service

The double metal shields help keep grit and dust out while retaining lubricant, which supports steady operation over many runs. This protective layout is useful whether you run on tarmac, carpet or light off-road surfaces.

Fits Many RC Applications

These bearings are a practical option for hobbyists swapping worn parts or upgrading stock components. Their 4x8x3mm size makes them compatible with numerous small-scale touring cars, buggies and RTR projects.

How do these bearings behave at high rpm

When installed and lubricated properly these double metal shield bearings run smoothly at higher speeds while the shields help keep contaminants out.

Do these come ready to fit or need prep

Check the seller listing for factory lubrication details. Many hobbyists clean and add a light bearing oil or grease before use to match their setup.

What maintenance keeps them lasting longer

Periodically remove debris, avoid blasting with pressurised water, and relubricate as needed. Replace bearings if you feel roughness or play.
