Performance Bearings for Consistent Drive

These 4x10x4mm 3Racing double metal shield bearings come in a 10 piece pack and give reliable support to rotating parts in RC models. They help cut friction and slow wear so drivetrain components run smoother for longer service intervals.

Performance Highlights

Durability: Double metal shields keep dirt and grit out to extend bearing life under normal running conditions.
Precision Fit: Engineered to the 4x10x4mm standard for a close fit in common hubs and carriers for steady rotation.
Versatile Application: Well suited for both carpet and loose-surface use across a range of on-road and off-road models.

Can these bearings handle high RPM on track cars?

Yes. The metal shields help limit contamination so bearings maintain smoother rotation at higher speeds, though proper lubrication and mounting matter too.

What maintenance should I perform?

Inspect for play and roughness, clean around the seals, and replace if you notice noise or binding. Sealed shields reduce how often service is needed.

Are these bearings compatible with 3mm axles?

They are sized 4x10x4mm, so check the hub bore and shaft diameter on your model; adapters or housings are sometimes required for different axle setups.
