Upgrade Bearings for Smoother Runs

If you want consistent rolling and lower friction, the 3RACING Double Metal Shield Bearings 3 x 8 x 4 mm in this 10 piece pack are a practical choice. These bearings help restore smooth rotation to axles and rotating parts during routine service or light upgrades.

Shielded Construction for Longer Service

The double metal shield gives extra protection from grit and grime, helping bearings resist contamination under normal use. Sized at 3 x 8 x 4 mm, they suit many common RC mounting points and help maintain predictable drivetrain feel.

Where to Use Them

These bearings work well for on-road and general off-road models, from gearboxes to wheel hubs. Their simple, robust build makes them a good first replacement when tracking down vibration or drag.

Can these bearings replace worn hub bearings?

They can replace many standard hub or shaft bearings that use the 3 x 8 x 4 mm size, but confirm the spacer and snap ring fits for your particular hub before installing.

Should I grease or oil these bearings?

Light oil is common for speed and responsiveness, while a small amount of grease helps protection in dusty conditions. Use a purpose RC bearing oil or light mineral oil for best results.

How do I check if a bearing is failing?

Spin the bearing by hand to feel for roughness or grinding and check for play on the shaft. Noticeable noise or wobble means replacement is recommended.
