Keep Bearings Cleaner with 3RACING Sealed Units

The 3RACING Double Rubber Sealed Bearings 8x12x3.5mm (2 pcs) - 3RB-MR128-2RS/2 are built to limit contaminant ingress and extend service intervals. The double rubber barriers help maintain smooth rotation and reduce the need for frequent cleaning.

How Seals Improve Performance

Rubber-sealed bearings stop particles and moisture from reaching the races and balls, so friction and wear are reduced. This is especially useful when running on loose surfaces or after light water exposure.

Common Uses on RC Models

These bearings are compatible with a broad range of 1/10 scale vehicles and are ideal for wheel hubs, diff outdrives and other stressed pivot points where steady rotation reduces drivetrain noise and heat.
