Tamiya 42380 950 Sealed Ball Bearings Set 2-Pack  [42380]

Smooth Rotation Upgrade for RC Models

The Tamiya 42380 sealed ball bearings improve rotational efficiency and reduce friction in drivetrain and wheel assemblies. These precision sealed bearings are a practical swap for hobbyists moving away from standard plastic or unsealed metal bearings.

Performance Benefits and Care

Each bearing features blue rubber seals that help keep grit and dust out of the race, making cleaning and service easier than with metal-sealed types. A low-viscosity oil inside the unit lowers friction and wear, supporting consistent running with less resistance.

Where to Use These Bearings

While commonly installed around the motor mount on TB-05 chassis layouts, the Tamiya 42380 bearings are versatile and can be fitted in many other RC positions where the size matches. They provide a straightforward upgrade path for several model types.

Keeping Bearings Running Smooth

Regular checks after heavy use or impacts will keep performance steady. Add a small amount of light bearing oil periodically and confirm free rotation to maintain long service life.
