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.
Metal shields provide a barrier to particulate ingress while maintaining smooth rolling action, which reduces maintenance frequency for hobby use.
Perfect for tight-fitting hubs, shafts and other small locations, these bearings are a straightforward swap to improve drivetrain smoothness.
