Small Shielded Bearings for Reliable Rotation

The 3RACING 1.5 x 4 x 2 mm double metal shield bearings are built for steady, low-drag performance in compact RC components. Their shielded construction helps fend off dust and grit for longer service life.

Built to resist contamination

Metal shields provide a barrier to particulate ingress while maintaining smooth rolling action, which reduces maintenance frequency for hobby use.

Typical uses

Perfect for tight-fitting hubs, shafts and other small locations, these bearings are a straightforward swap to improve drivetrain smoothness.

Are these bearings serviceable once installed?

They can be cleaned and lightly relubricated, but care is needed due to the small size; removal from the assembly is often required for full service.

Do these bearings come as single units or a pair?

This listing is for two pieces, matching the standard small bearing pairs used in many RC assemblies.
