3RACING 3RB-MR106-2RS/2 6x10x3mm Race-Grade Double Rubber Seal Bearings (2)  [3RB-MR106-2RS/2]

Race-Focused Bearing Choice for Tuned Drivetrains

The 3RACING 3RB-MR106-2RS/2 is a 6 x 10 x 3 mm double rubber sealed bearing engineered for low friction and reliable seal performance in competitive RC applications. Its compact size and sealed design suit precision wheel hubs, idlers, and gearbox outputs where consistent performance matters.

Performance and Tuning Considerations

These sealed bearings balance reduced drag with robust contamination protection, making them ideal for setups that require dependable spin without frequent rebuilds. Their sealed construction helps preserve lubrication under extended runs and varied track conditions.

Workshop Best Practices

For optimal results, verify shaft tolerances and press the bearing into a clean, correctly sized bore to prevent misalignment. Use a bearing driver to protect the seal and inspect for axial play during setup; replace bearings that show noise or roughness to maintain drivetrain efficiency.
