Reliable Bearing Choice for Hobby Runners

The 3RACING Double Metal Shield Bearing in 4x8x3mm is a practical spare for club runs and weekend builds. This compact pair is aimed at improving axle spin and reducing unwanted drag in small-scale RC models.

Shield Features That Matter

With metal shields on both sides these bearings resist coarse dirt and help keep lubricant in place, which extends usable life between services. That makes them suitable for general on-road and light off-road use.

Easy Upgrade and Service Use

These bearings are compatible with many touring cars, buggies and ready-to-run vehicles that use 4x8x3mm bearings. They are straightforward to replace during routine maintenance or when refreshing running gear.

Can I use these in a brushless setup

Yes, these bearings are suitable for both brushed and brushless applications as long as the dimensions match your hubs and shafts.

Should I relubricate before first run

If you notice factory grease is light or absent, add a small amount of bearing oil to suit your track conditions; this can improve rolling feel.

How do I spot a worn bearing

Look for roughness, excess play or noise under spin. Replace bearings if you detect grinding or uneven rotation.
