Compact Bearing Upgrade for RC Cars

If you want to tighten up wheel spin and reduce drivetrain drag, the 3RACING 3RB-681X-ZZ/2 double metal shield bearings are a straightforward upgrade. At 1.5 x 4 x 2 mm these bearings are built to deliver smooth rotation and reliable service for both track sessions and weekend runs.

Shielded Design for Tough Conditions

The double metal shields help keep dust and grit out while retaining lubricant inside the race. That protection supports consistent performance when running on mixed surfaces or in dusty environments.

Where to Fit These Bearings

The small footprint of these bearings makes them compatible with a variety of hubs, idlers and gearbox locations. Use them in high-speed builds or compact off-road rigs to help extend service life and maintain efficient operation.

Will 1.5 x 4 x 2 mm bearings fit standard 1/10 wheel hubs?

Measure the bore and shaft you intend to use them on; the 3RB-681X-ZZ/2 is a standard small bearing that fits many compact hubs and gearbox shafts used in smaller scale RC cars.

How do metal shields compare to rubber seals?

Metal shields block larger debris and allow lower friction than many rubber sealed bearings, but they are not fully sealed against liquid ingress. They are a good balance for dry or dusty running.

Any maintenance tips for these bearings?

Keep wheels and hubs clean, avoid soaking bearings in water, and use a light bearing oil or grease sparingly to extend life while keeping friction low.
